5.1 This test method is intended for the determination of the arc rating of a material, or a combination of materials.5.1.1 Because of the variability of the arc exposure, different heat transmission values may be observed at individual sensors. Evaluate the results of each sensor in accordance with Section 12.5.2 This test method maintains the specimen in a static, vertical position and does not involve movement except that resulting from the exposure.5.3 This test method specifies a standard set of arc exposures performed under controlled laboratory conditions. Different exposure conditions have the potential to produce different results. In addition to the standard set of exposure conditions, other conditions representative of the expected hazard may be used and shall be documented in the reporting of the testing results.1.1 This test method is used to determine the arc rating of materials intended for use as flame resistant clothing for workers exposed to electric arcs that would generate heat flux rates of approximately 2100 kW/m2 [50 cal/cm2s] using an open air arc.1.2 This test method will determine the arc rating of materials which meet the following requirements: less than 150 mm [6 in.] char length and less than 2 s afterflame when tested in accordance with Test Method D6413.1.2.1 It is not the intent of this test method to evaluate non flame-resistant materials.1.3 The materials used in this test method are in the form of flat specimens.1.4 This test method shall be used to measure and describe the properties of materials, products, or assemblies in response to convective and radiant energy generated by an electric arc under controlled laboratory conditions.1.5 The values stated in SI units shall be regarded as standard except as noted. Within the text, alternate units are shown in brackets. The values stated in each system may not be exact equivalents therefore alternate systems must be used independently of the other. Combining values from the systems described in the text may result in nonconformance with the method.1.6 This test method does not apply to electrical contact or electrical shock hazards.1.7 This standard shall not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

5.1 This test method evaluates puncture resistance of protective clothing materials which may include plastics or elastomeric films, coated fabrics, flexible materials, laminates, or textile materials.5.2 This test method is not intended to measure puncture resistance of all types of punctures encountered using protective clothing material. This test method involves a procedure where a puncture probe of specified dimensions is used for puncturing specimens.5.3 This test method evaluates puncture resistance of protective clothing materials, specifically for puncture forced on specimens perpendicular to material surface. There is no supporting structure under the material specimen.5.4 Evaluation of puncture resistance for snag-type puncture should be performed in accordance with Test Method D2582.1.1 This test method determines the puncture resistance of a protective clothing material specimen by measuring the force required to cause a pointed puncture probe to penetrate through the specimen. This test method describes three protocols that may be used: Method A, Method B, and Method C.1.1.1 Method A requires the use of Probe A only. The probe used for testing shall be recorded in the test report.1.1.1.1 Probe A may be used to measure puncture resistance for the following types of materials:(1) Elastomeric materials,(2) Textiles, and(3) Coated materials.1.1.2 Method B requires the use of Probe B. The probe used for testing shall be recorded in the test report.1.1.2.1 Probe B may be used to measure puncture resistance for the following types of materials:(1) Textiles.(2) Coated materials.NOTE 1: Probe B is not suited for measuring the puncture resistance of unsupported elastomeric materials.1.2 The values stated in SI units are to be regarded as the standard.

5.1 Use this test method to measure the thermal protection provided by different materials, garments, clothing ensembles, and systems when exposed to a specified fire (see 3.2.2, 3.2.3, 4.1, and 10.4).5.1.1 This test method does not simulate high radiant exposures, for example, those found in electric arc flash exposures, some types of fire exposures where liquid or solid fuels are involved, nor exposure to nuclear explosions.5.2 This test method provides a measurement of garment and clothing ensemble performance on a stationary upright manikin of specified dimensions. This test method is used to provide predicted skin burn injury for a specific garment or protective clothing ensemble when exposed to a laboratory simulation of a fire. It does not establish a pass/fail for material performance.5.2.1 This test method is not intended to be a quality assurance test. The results do not constitute a material’s performance specification.5.2.2 The effects of body position and movement are not addressed in this test method.5.3 The measurement of the thermal protection provided by clothing is complex and dependent on the apparatus and techniques used. It is not practical in a test method of this scope to establish details sufficient to cover all contingencies. Departures from the instructions in this test method have the potential to lead to significantly different test results. Technical knowledge concerning the theory of heat transfer and testing practices is needed to evaluate if, and which departures from the instructions given in this test method are significant. Standardization of the test method reduces, but does not eliminate, the need for such technical knowledge. Report any departures along with the results.1.1 This test method is used to provide predicted human skin burn injury for single-layer garments or protective clothing ensembles mounted on a stationary upright instrumented manikin which are then exposed in a laboratory to a simulated fire environment having controlled heat flux, flame distribution, and duration. The average exposure heat flux is 84 kW/m2 (2 cal/s·cm2), with durations up to 20 s.1.2 The visual and physical changes to the single-layer garment or protective clothing ensemble are recorded to aid in understanding the overall performance of the garment or protective clothing ensemble and how the predicted human skin burn injury results can be interpreted.1.3 The skin burn injury prediction is based on a limited number of experiments where the forearms of human subjects were exposed to elevated thermal conditions. This forearm information for skin burn injury is applied uniformly to the entire body of the manikin, except the hands and feet. The hands and feet are not included in the skin burn injury prediction.1.4 The measurements obtained and observations noted can only apply to the particular garment(s) or ensemble(s) tested using the specified heat flux, flame distribution, and duration.1.5 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.1.6 This method is not a fire test response test method.1.7 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units or other units commonly used for thermal testing. If appropriate, round the non-SI units for convenience.1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.9 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.1.10 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method is intended for the determination of the radiant heat resistance value of a material, a combination of materials, or a comparison of different materials used in flame-resistant clothing for workers exposed to radiant thermal hazards.5.2 This test method evaluates a material's heat transfer properties when exposed to a continuous and constant radiant heat source. Air movement at the face of the specimen and around the calorimeter can affect the measured heat transferred due to forced convective heat losses. Minimizing the air movement around the specimen and test apparatus will aid in the repeatability of the results.5.3 This test method maintains the specimen in a static, vertical position and does not involve movement, except that resulting from the exposure.5.4 This test method specifies two standard sets of exposure conditions: 21 kW/m2 (0.5 cal/cm2s) and 84 kW/m2 (2.0 cal/cm2s). Either can be used.5.4.1 If a different set of exposure conditions is used, it is likely that different results will be obtained.5.4.2 The optional use of other conditions representative of the expected hazard, in addition to the standard set of exposure conditions, is permitted. However, the exposure conditions used must be reported with the results along with a determination of the exposure energy level stability.5.5 This test method does not predict skin burn injury from the standardized radiant heat exposure.NOTE 4: See Appendix X4 for additional information regarding this test method and predicted skin burn injury.1.1 This test method rates the non-steady state thermal resistance or insulating characteristics of flame resistant clothing materials subjected to a continuous, standardized radiant heat exposure.1.1.1 This test method is not applicable to clothing materials that are not flame resistant.NOTE 1: The determination of a clothing material's flame resistance shall be made prior to testing and done in accordance with the applicable performance standard, specification standard, or both, for the clothing material's end use.1.1.2 This test method does not predict skin burn injury from the standardized radiant heat exposure, as it does not account for the thermal energy contained in the test specimen after the exposure has ceased.NOTE 2: See Appendix X4 for additional information regarding this test method and predicted skin burn injury.1.2 This test method is used to measure and describe the response of materials, products, or assemblies to heat under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound or other units that are commonly used for thermal testing.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 This test method is intended to determine the ignition resistance and burning characteristics of materials used in protective clothing where flame resistance is not the primary form of protection designated.5.1.1 Flame resistance is a distinctive property of clothing items designated for isolating parts of the body from anticipated flame hazards. It is possible that protective clothing designated for isolation from other hazards, such as those for chemical or biological protection, neither have flame resistance nor isolate the wearer from flame hazards. This test method can be used to evaluate the effects of flame impingement on protective clothing where flame resistance is not the primary objective of protection.5.1.2 When flame resistance is the primary protection offered by the protective clothing, alternative test methods can be used. A test method that is useful for evaluating flame resistance of textiles is Test Method D6413/D6413M. Classification Index D4723 contains descriptions and guidance on other flammability test methods for textiles.5.1.3 This test method is useful to determine the ignition resistance and burning characteristics of materials used in protective clothing not designated for flame resistance when the outer material surface is exposed to the flame. As such, it is particularly suited to protective clothing materials that are composed of different layers such as coated fabrics, laminates, or multilayer clothing systems.5.2 Alternative procedures for conducting either a 3-s or 12-s exposure are provided where one or the other flame application exposure times are applied. The choice of either the shorter or longer single exposure time is provided to permit an assessment of the effects for flame impingement on materials under short-term and long-term flame exposure conditions.5.3 Correlation of data from this test method with the ignition resistance and burning characteristics of protective clothing (not designated for flame resistance) under actual use conditions is not implied.1.1 This test method establishes a small-scale laboratory screening procedure for comparing the ignition resistance and burning characteristics of materials used in protective clothing where flame resistance is not the primary form of protection provided by the clothing.1.1.1 This test method shall not be used in applications where flame resistance is the primary form of protection offered by the protective clothing. Other flammability test methods are more appropriate for those materials.1.1.2 This test method provides a means for comparing ease of ignition and burning behavior of materials which include plastic or elastomeric films, coated fabrics, flexible laminates, multilayer material systems, or other protective clothing materials that are not designated for offering flame resistance as their primary form of protection.1.2 This test method is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.1.3 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.1.4 The values stated in SI units or other units shall be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method evaluates the ability of the construction and configuration of protective clothing or protective ensembles to resist liquid penetration. In most cases, the conditions used in this test method will not represent actual end-use conditions.5.2 Two different spray configurations are used for exposing the protective clothing or protective ensemble on a manikin.5.2.1 Procedure A involves five shower nozzles, with one nozzle directly above the clothed manikin and two nozzles each to upper and lower sides of the manikin that are all positioned in the same vertical plane. This spray configuration is intended to provide a full exposure of the entire protective clothing or protective ensemble system.5.2.2 Procedure B involves three shower nozzles that are positioned at different heights on a vertical line that is parallel to the manikin with the locations and direction of each nozzle set with respect to targets on the manikin. This spray configuration is intended to provide a direct assessment of garment features such as the front closure.5.3 The selected duration of the test is not intended to simulate user exposure to splashes of liquid substances but rather to provide sufficient time for enough liquid to penetrate to make visual detection easier. The default liquid exposure time for Procedure A is 20 min. The default liquid exposure time for Procedure B is 10 min.5.3.1 It is permissible to specify shorter test durations. It is recommended that the duration of exposure be the same in each manikin orientation.5.3.2 The choice of different test duration is partly based on the number of layers in the specimen being tested, some of which serve to absorb the surfactant-treated test liquid and result in attenuating the severity of the liquid challenge to the specimen.5.4 A nontoxic, non-foaming surfactant is added to water for this test method to simulate liquids of lower surface tensions. Liquids of specific interest can be simulated by treating water to achieve an equivalent surface tension.5.5 For protective clothing with water-repellent surfaces, the lower surface tension liquid will aid in the evaluation of the construction and configuration of the garment because it is less likely to be repelled and more likely to wet the protective clothing. This is especially useful for reusable garments whose water-repellent surface interferes with the evaluation of their construction and configuration when new, but is diminished after wearing and washing.5.6 Fluorescent or colored dyes are permitted to be added to the water to enhance detection of liquid penetration into the protective clothing or protective ensemble.5.7 This test method can be used by both manufacturers and end users to assess liquid penetration resistance. Manufacturers can use this test method to evaluate quality of construction and effectiveness of clothing and ensemble configurations.5.8 The clothing or ensemble is sized to fit the manikin. It is important that the clothing be selected to fit the manikin well since detection of liquid penetration requires as much contact as possible between the clothing or ensemble and the inner liquid-absorptive garment.5.9 Results on a mismatched size of clothing or ensemble shall not be used to generalize about a particular construction or configuration. Manikin fit potentially affects liquid penetration resistance determinations.5.10 There are no known restrictions to the types of protective clothing or protective ensembles that can be evaluated with this test method.5.11 In some cases protective clothing or protective ensembles that show no liquid penetration during this test method will still fail to protect wearers against specific liquids due to the material degradation, penetration, or permeation or the effects associated with the vapors of liquid chemicals.5.12 In some cases protective clothing or protective ensembles that show no liquid penetration during this test method will fail to protect wearers in specific circumstances as, for example, deluge or immersion.1.1 This test method measures the ability of protective clothing or protective ensembles to resist liquid penetration in the form of a shower spray with surfactant-treated water.1.2 This test method measures the liquid penetration resistance of the construction and configuration of the overall protective clothing or protective ensemble, but especially of seams, closures, and interfaces with other components such as gloves, boots, hoods, and respiratory protective equipment. It is intended that this test method be used to assess the liquid penetration resistance of protective clothing and protective ensembles as received from the manufacturer and worn in accordance with their instructions.1.3 Resistance of materials used in protective clothing to permeation or penetration can be determined in accordance with Test Method F739 (or Test Method F1383 or F1407) and Test Method F903, respectively. Alternatively, resistance of materials used in protective clothing to penetration by synthetic blood or liquids containing virus can be determined in accordance with Test Methods F1670/F1670M and F1671/F1671M.1.4 The integrity of vapor protective ensembles is measured by its ability to maintain positive internal pressure with Test Method F1052.1.5 The values in SI units or in other units shall be regarded separately as standard. The values stated in each system must be used independently of the other, without combining values in any way.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method is used to evaluate the heat resistance of materials, clothing, and equipment when exposed to heat in a hot air circulating oven. The principal findings of this test method are observations of the specimen response to the heat exposure.5.1.1 The majority of procedures specified in this test method apply to the evaluation of flat material specimens.5.1.2 When evaluating non-flat materials, alternative procedures are required for mounting specimens and interpreting the effects of the heat exposure.5.2 If specified, this test method is used for the measurement of material dimensional change following a convective heat exposure in a hot air circulating oven.5.3 This test method is not intended to simulate the actual exposure of material, clothing, or equipment in high-heat conditions such as a fire environment.1.1 This test method covers quantitative measurements and subjective observations that characterize the performance for evaluating the heat resistance of materials, protective clothing, and equipment when exposed in a hot air circulating oven.1.2 This test method is intended to evaluate physical changes in materials, protective clothing, and equipment at a specified heat exposure.1.2.1 The specified heat exposure in the hot air circulating oven is a combination of convective heat and radiant heat.1.3 Materials, protective clothing, and equipment are evaluated for visible changes or subjected to a material property measurement following a specified heat exposure.1.3.1 This test method is not to be used for the evaluation of sticking. An acceptable method for evaluating sticking of fabrics is described in NFPA 1975, Sections 7.2.1 and 8.3. The NFPA 1975 test method evaluates the thermal stability of specimens by assessing the blocking of folded specimens placed between glass plates, under a specified weight, inside an oven meeting the same characteristics of the oven used in this test method.1.4 This test method enables the quantitative measurement of dimensional change that occurs as a result of a specified heat exposure in a hot air circulating oven.1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to other units that are commonly used for thermal testing.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.NOTE 1: Flame-resistant and heat-resistant materials are described in a range of different standards and meet a range of different requirements. For materials tested in accordance with this test method, the applicable standard shall be used to establish preconditioning, conditioning, and testing conditions and requirements.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method is used to measure chemical permeation through specimens of protective clothing under the condition of intermittent contact of a test chemical with the specimen. In many applications, protective clothing is contacted intermittently to chemicals, not continuously as is tested by Test Method F739.5.2 This test method is normally used to evaluate flat specimens and seams from finished items of protective clothing and of materials that are candidates for items of protective clothing.5.2.1 Finished items of protective clothing include gloves, sleeves, aprons, suits, coveralls, hoods, boots, respirators, and the like.5.2.2 The phrase “specimens from finished items” encompasses seams or other discontinuous regions as well as continuous regions of protective clothing items.5.2.3 Selected seams for testing are representative of seams used in the principal construction of the protective clothing item and typically include seams of both the base material and where the base material is joined with other types of materials.5.3 In some cases, it may be of interest to compare permeation behaviors that occur under conditions of intermittent contact with those that occur during continuous contact. Test Method F739 is recommended for measuring permeation under the conditions of continuous contact of the test chemical with the protective clothing specimen.5.4 The breakthrough detection time, standardized breakthrough time, and the cumulative permeation are key measures of the effectiveness of a clothing material to be a barrier to the test chemical. Such information is used in the comparison of clothing materials during the process of selecting clothing for protection from hazardous chemicals. Long breakthrough detection times and standardized breakthrough times and low amounts of cumulative permeation are characteristics of more effective barrier materials than materials with higher permeation characteristics.NOTE 1: At present, there is limited quantitative information about acceptable levels of dermal contact with most chemicals. Therefore, the data obtained using this test method cannot be used to infer safe exposure levels.5.4.1 The reporting of a standardized breakthrough time greater than a specific time period does not mean that no chemical permeated through the protective clothing material since the standard breakthrough time is determined based on the permeation rate reaching a level of 0.1 μg/cm2/min. Some chemical had already permeated the specimen prior to the reported standardized breakthrough time.5.4.2 The reporting of cumulative permeation over a specified test period is another means to report barrier performance of protective clothing for resistance to permeation. This measurement quantifies the total amount of chemical that passed through a known area of the material during the specified test period.NOTE 2: It is possible to relate cumulative permeation test results to the total amount of chemical to which an individual wearer may be exposed by accounting for the exposed surface area and the underlying air layer. This information has potential value when there are known maximum permitted skin exposure doses for specific chemicals.5.5 The sensitivity of the test method in detecting low permeation rates or amounts of the test chemical permeated is determined by the combination of: (1) the analytical technique and collection system selected, and (2) the ratio of material specimen area to collection medium volume or flow rate.5.5.1 The analytical technique employed shall be capable of measuring the concentration of the test chemical in the collection medium at or below 0.05 μg/cm2/min.5.5.2 Often, permeation tests will require measurement of the test chemical over several orders of magnitude in concentration, requiring adjustments in either the sample collection volume or concentration/dilution, or the analytical instrument settings over the course of the test.5.5.3 Higher ratios of material specimen area to collection medium volume or flow rate permit earlier detection of permeation because higher concentrations of the test chemical in the collection medium will develop in a given time period, relative to those that would occur at lower ratios.5.5.4 The sensitivity of an open-loop system is characterized by its minimum detectable permeation rate. A method for determining this value is presented in Appendix X1.5.5.5 The sensitivity of a closed-loop system is characterized by its minimum detectable mass permeated.5.6 Comparison of results of tests performed with different permeation test systems requires specific information on the test cell, procedures, contact and purge times, and analytical techniques. Results obtained from closed-loop and open-loop testing may not be directly comparable.5.7 While this method specifies standardized breakthrough time as the time at which the permeation rate reaches 0.1 μg/cm2/min, it is acceptable to continue the testing and also report a normalized breakthrough time at a permeation rate of 1.0 µg/cm2/min.5.7.1 It is permitted to terminate tests early if there is catastrophic permeation of the chemical through the protective clothing material and the rate of permeation could overwhelm the capability of the selected analytical technique.5.8 A group of chemicals that is commonly used in permeation testing is given in Guide F1001.5.9 Guide F1194 provides a recommended approach for reporting permeation test results.1.1 This test method measures the permeation of liquids and gases through protective clothing materials under the condition of intermittent contact.1.2 This test method is designed for use when the test chemical is a gas or a liquid, where the liquid is either volatile (that is, having a vapor pressure greater than 1 mm Hg at 25 °C) or soluble in water or another liquid that does not interact with the clothing material.1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 7.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Two levels of protective clothing barrier material and seam performance are established for complying with Part A labeling requirements specific to these seven liquid chemotherapy drugs.1.1.1.1 Broad chemotherapy drug protection is based on the protective clothing barrier material and seams demonstrating breakthrough detection times of 30 min or more for the seven specified chemotherapy drugs.1.1.1.2 Selective chemotherapy drug protection is based on the protective clothing barrier material and seams demonstrating breakthrough detection times of 30 min or more for at least five of the seven specified chemotherapy drugs.1.1.2 It is also possible to report permeation resistance test results for additional liquid chemotherapy and other liquid hazardous drugs of interest as determined by the manufacturer or end user organization using the same breakthrough detection criteria for individual drugs for complying with the Part B labeling requirements.1.1.3 Protective clothing meeting this specification is also required to meet minimum flammability requirements, and if used as a medical device, biocompatibility (if used for breached skin contact), and demonstrate sterility assurance, if sterilized prior to use.1.1.4 Physical properties that indicate the strength, durability, and breathability of the protective clothing are optionally reported.1.1.5 Additional requirements are established for the label and user information to be provided for protective clothing meeting this specification.1.1.6 This specification also requires products intended to be used as medical devices such as surgical gowns and isolation gowns to meet the respective requirements of AAMI PB70, Specification F2407/F2407M, and Specification F3352/F3352M, as applicable.1.2 This specification does not address all conditions of exposure for individuals who wear protective clothing in the manufacture, transport, compounding, preparation, and administration of liquid chemotherapy and other hazardous drugs in addition to patient care activities and spills where contaminated items with these drugs are encountered.1.3 This specification does not address chemotherapy drugs or hazardous drugs that may be encountered in the form of a vapor or aerosol and does not provide any criteria for respiratory protection.1.4 This specification does not address the selection, use, or care of protective clothing used for protection against liquid chemotherapy or other liquid hazardous drugs. While this specification does not specifically determine which barrier material to select, the results of the tests described in this specification are useful for selecting barrier materials by comparing the test results among different materials under consideration. See USP 800, Hazardous Drugs—Handling In Healthcare Settings, for specific guidelines on the selection, use, and care of personal protective equipment for protection of healthcare workers against chemotherapy or other hazardous drugs.1.5 This specification is intended to provide the basis for manufacturers or suppliers to make specific claims that protective clothing products provide protection against liquid chemotherapy and other liquid hazardous drugs.1.6 The values stated in SI units or in other units shall be regarded separately as standard. The values stated in each system must be used independently of the other, without combining values in any way.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method is intended for the determination of the heat transfer performance value of a material, a combination of materials, or a comparison of different materials used in flame-resistant clothing for workers exposed to combined convective and radiant thermal hazards.5.2 This test method evaluates a material’s unsteady-state heat transfer properties when exposed to a continuous and constant heat source. Air movement at the face of the specimen and around the calorimeter can affect the measured heat transferred due to forced convective heat losses. Minimizing air movement around the specimen and test apparatus will aid in the repeatability of the results.5.3 This test method maintains the specimen in a static, horizontal position and does not involve movement except that resulting from the exposure.5.4 This test method specifies a standardized 84 ± 2 kW/m2 (2 ± 0.05 cal/cm2s) exposure condition. Different exposure conditions have the potential to produce different results. Use of other exposure conditions that are representative of the expected hazard are allowed but shall be reported with the results along with a determination of the exposure energy level stability.5.5 This test method does not predict skin burn injury from the heat exposure.NOTE 4: See Appendix X4 for additional information regarding this test method and predicted skin burn injury.1.1 This test method measures the non-steady state heat transfer through flame-resistant materials for clothing subjected to a continuous, combined convective and radiant heat exposure.1.1.1 This test method is not applicable to materials that are not flame resistant.NOTE 1: The determination of a material’s flame resistance shall be made prior to testing and done according to the applicable performance or specification standard, or both, for the material’s end-use.1.1.2 This test method does not predict a material’s skin burn injury performance from the specified thermal energy exposure. It does not account for the thermal energy contained in the test specimen after the exposure has ceased.NOTE 2: See Appendix X4 for additional information regarding this test method and predicted skin burn injury.1.2 This test method is used to measure and describe the response of materials, products, or assemblies to heat under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound or other units that are commonly used for thermal testing.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.1 This test method is used to measure the heat energy transmission through materials used in protective clothing and gloves that are exposed to a Hot Liquid Splash. This test method is applicable to woven fabrics, knit fabrics, battings, and sheet structures with permeable or impermeable coatings or laminations intended for use as clothing or gloves for protection against brief exposures to hot liquid splash hazards.1.2 This test method is used to measure and describe the properties of materials or assemblies of materials in response to hot liquids under controlled laboratory conditions.1.3 This test method is applicable to materials from which finished protective apparel articles are made.1.4 This test method is limited to the hot liquid temperatures that are 40°C (72°F) below the flash point of the specific hot liquid used for testing.Note 1—Specific thermally stable silicone liquids are available with flash points in the range of 315°C (599°F). When these thermally stable silicone liquids are used, a maximum hot liquid temperature of 260°C (500°F) is achievable. The intent of specifying the maximum temperature at 40°C (72°F) below the liquid flash point is to reduce the hot liquid fire hazard which increases significantly at temperatures equal to or above the flash point of the liquid.1.5 This test method does not measure the flammability of materials, nor is it intended for use in evaluating materials exposed to any other thermal exposure other than hot liquid exposures.1.6 The values as stated in SI units are to be regarded as the standard. The values in parentheses are given for information only.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 8.

5.1 This test method is intended for the determination of the radiant heat performance value of a material, a combination of materials, or a comparison of different materials used in flame resistant clothing for workers exposed to radiant thermal hazards.5.2 This test method evaluates a material’s heat transfer properties when exposed to a heat exposure at a constant value and systematically varied durations. Air movement at the face of the specimen and around the calorimeter can affect the measured heat transferred due to forced convective heat losses. Minimizing air movement around the specimen and test apparatus will aid in the repeatability of the results.5.3 This test method accounts for the thermal energy contained in the exposed test specimen after the radiant heat exposure has ceased. Higher values of Radiant Heat Performance rating determined in this test associate to higher values of radiant energy protection against a predicted skin burn injury.5.4 This test method maintains the specimen in a static, vertical position and does not involve movement except that resulting from the exposure procedure.5.5 This test method specifies two standard sets of exposure conditions, 21 kW/m2 (0.5 cal/cm2s) and 84 kW/m2 (2.0 cal/cm2s). Either can be used.5.5.1 If a different set of exposure conditions is used, it is likely that different results will be obtained.5.5.2 The optional use of other conditions representative of the expected hazard, in addition to the standard set of exposure conditions, is permitted. However, the exposure conditions used must be reported with the results along with a determination of the exposure energy level stability.1.1 This test method measures thermal protective characteristics of flame resistant textile materials subjected to a standardized radiant heat exposure relative to a predicted second-degree skin burn injury.1.1.1 This test method is not applicable to textile materials that are not flame resistant.NOTE 1: The determination of a textile material’s flame resistance shall be made prior to testing and done according to the applicable performance or specification standard, or both, for the textile material’s end-use.1.1.2 This test method accounts for the thermal energy contained in an exposed test specimen after the standardized radiant heat exposure has ceased.1.2 This test method is used to measure and describe the response of materials, products, or assemblies to heat under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound or other units that are commonly used for thermal testing.1.4 This standard does not purport to address the safety concerns, if any, associated with its use.
