5.1 The XRF instrument is used to measure the lead content in paint films in buildings and related structures in order to determine the potential lead hazard and the possible need for in-place control or abatement, or both.5.2 This practice also is to be used for the laboratory evaluation of the performance of portable X-ray fluorescence instrumentation.5.3 This practice is to be used as a guide for determining that the manufacturer of portable X-ray instrumentation has met certain requirements, most of which deal with instrument construction.5.4 The evaluation may be performed by the manufacturer, or an independent party. The results may be presented to various government agencies and, upon request, potential purchasers and users of the instrumentation. All or parts of this practice also may be performed by an X-ray instrument owner/user to determine the acceptability of an instrument or whether the performance of an instrument continues to be acceptable, or both.5.5 This practice may be used by field testers for quality control by performing selected activities described in the document on a regular and recurring basis in a manner similar to those protocols followed by users of laboratory instruments.5.6 Limitation—Bias and precision, as determined in the laboratory by this practice, together provide only an estimate of the accuracy that may be achieved in the field. Accuracy in the field will depend upon the instrument calibration, the form and composition of the substrate, the structure of the paint film being analyzed, as well as other factors.1.1 This practice covers portable X-ray fluorescence (XRF) instruments intended for the measurement of lead in paint. It is intended that manufacturers apply this practice to one unit of a particular model of an instrument when that model is initially available. Replicate tests on additional units of the same model of an instrument are to be performed at the discretion of the manufacturer. This practice also is intended for use by third parties performing independent evaluation of portable X-ray fluorescence instruments.1.2 All performance evaluation data are to be in SI units.1.3 Tests of performance are based on replicate measurements of certified reference paint films on a variety of substrate materials. Tests are performed to determine: bias, precision, linearity, limit of detection, interferences, substrate affects, and stability.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 and health practices and determine the applicability of regulatory limitations prior to use.

5.1 Evaluation of the impact toughness of film is important in predicting the performance of a material in applications such as packaging, construction, and other uses. The test simulates the action encountered in applications where moderate-velocity blunt impacts occur in relatively small areas of film.5.2 The values obtained by this test method are highly dependent on the method and conditions of film fabrication as well as the type and grade of resin.5.3 Test methods employing different missile velocities, impinging surface diameters, or effective specimen diameters will most likely produce different results. Data obtained by this test method cannot necessarily be compared directly with those obtained by other test methods.5.4 The impact resistance of a film, while partly dependent on thickness, does not have a simple correlation with sample thickness. Hence, impact values expressed in joules [ft·lbf] normalized over a range of thickness will not necessarily be linear with thickness. Data from this test method are comparable only for specimens that vary by no more than ±15 % from the nominal or average thickness of the specimens tested.5.5 The test results obtained by this test method are greatly influenced by the quality of film under test. The influence of variability of data obtained by this procedure will, therefore, depend strongly on the sample quality, uniformity of film thickness, the presence of die marks, contaminants, etc.5.6 Several impact test methods are used for film. It is sometimes desirable to know the relationships among test results derived by different test methods. A study was conducted in which four films made from two resins (polypropylene and linear low-density polyethylene), with two film thicknesses for each resin, were impacted using Test Methods D1709 (Test Method A), Test Method D3420 (Procedures A and B), and Test Method D4272. The test results are shown in Appendix X2. Differences in results between Test Methods D1709 and D3420 are expected since Test Methods D1709 represents failure-initiated energy, while Test Method D4272 is initiation plus completion energy. It is possible some films show consistency when the initiation energy is the same as the total energy. This statement and the test data also appear in the significance and appendixes sections of Test Methods D1709 and D3420.1.1 This test method describes the determination of the total energy impact of plastic films by measuring the kinetic energy lost by a free-falling dart that passes through the film.1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard1.3 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: Film has been arbitrarily defined as sheeting having nominal thickness not greater than 0.25 mm [0.010 in.].NOTE 2: This test method and ISO 7765–2 address the same subject matter, but differ in technical content (and results cannot be directly compared between the two test methods). The ISO test method calls for a direct readout of energy by using a load cell as part of the impactor head, while Test Method D4272 calls for a constant weight impactor, then measuring the time of travel through a given distance to get energy values.FIG. 1 Elements of an Instrumented Dart Drop System1.4 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.

The test method shall measure the deposit formation tendencies of liquids on steel surfaces in air at 101.3 KPa (1-atm) pressure. Other surfaces and other atmospheric media may be substituted for steel and air at 1 atm provided that the substitution is noted in the test report.1.1 This test method covers the determination of the tendency of liquids in thin films and of vapors to form deposits on metal surfaces. The test method applies to both petroleum-based and synthetic lubricants, hydraulic fluids, heat-transfer fluids, and related materials.1.2 The values stated in SI units are to be regarded as the standard. In cases where materials, products, or equipment are available in inch-pound units only, SI units are omitted.1.3 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.

4.1 This test method is designed to provide load versus deformation response of plastic films under essentially multi-axial deformation conditions at impact velocities. This test method further provides a measure of the rate sensitivity of the plastic films to impact.4.2 Multi-axial impact response, while partly dependent on thickness, does not necessarily have a linear correlation with specimen thickness. Therefore, results should be compared only for specimens of essentially the same thickness, unless specific responses versus thickness formulae have been established for the plastic films being tested.4.3 For many plastic films, it is possible that a specification exists that requires the use of this test method, but with some procedural modifications that take precedence when adhering to the specification. Therefore, it is advisable to refer to that material specification before using this test method. Table 1 of Classification System D4000 lists the ASTM materials standards that currently exist.4.4 The values obtained by this test method are highly dependent on the method and conditions of film fabrication as well as the type and grade of resin. Results can vary significantly, depending upon sample quality, uniformity of film gage, die marks, contaminants, and so forth.1.1 This test method covers the determination of puncture properties of plastic films, over a range of test velocities.1.1.1 ASTM Terminology Standard D883 has defined film as having a thickness not greater than 0.25 mm. Plastic materials having a thickness above this limit are not to be excluded from use unless shown to be rigid (see 3.2.1). Test Method D3763 is the recommended method for instrumented puncture testing of rigid plastics.1.2 Test data obtained by this test method is relevant and appropriate for use in engineering design.1.3 The values stated in SI units are to be regarded as 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.NOTE 1: This test method does not closely conform to ISO 7765-2. The only similarity between the two tests is that they are both instrumented impact tests. The differences in striker, fixture, specimen geometries and in test velocity can produce significantly different test results.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.

5.1 Materials such as engineered thermoplastic films are often used for flexible barrier packaging. However, handling and transportation can cause abrasion to the packaging film and possibly compromise the integrity of the contents (for example, sterility of a medical device). This test method provides a comparative ranking of material performance that can be used as an indication of relative end-use performance.5.2 The resistance of material surfaces to abrasion, as measured on a testing machine under laboratory conditions, is only one of several factors contributing to wear performance or durability as experienced in the actual use of the material. While abrasion resistance and durability are frequently related, the relationship varies with different end uses and different factors may be necessary in any calculation of predicted durability from specific abrasion data.5.3 The resistance of material surfaces to abrasion may be affected by factors including test conditions of temperature and humidity, type of abradant, pressure between the specimen and abradant, mounting or tension of the specimen, and type, kind, or amount of finishing materials such as coatings or additives. Other causes of variation include local material movement during testing, material direction alignment, material characteristics, and mandrel and stylus wear. For consistency, samples to be evaluated under special environmental conditions shall be conditioned under those same conditions. It is important that the test instrument be shown to operate properly under special environmental conditions.5.4 This test method may not be suitable for all films, including the following cases:5.4.1 Films that stretch and generate a ripple in the abraded region during testing,5.4.2 Films that have a thickness greater than 0.25 mm (0.010 in.), or are of such rigidity that forming over the mandrel would cause internal stresses that weaken the film, and5.4.3 Conductive films.1.1 This test method covers the determination of the abrasion resistance of flexible non-conductive films and packaging materials using a weighted stylus that wears completely through a film by oscillating or reciprocating back and forth along a linear path until an electrical circuit is completed shutting down the test.1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.3 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.1.4 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 guide is for testing the performance applied stretch wrapping film and stretch wrapping equipment during and after the film has been applied to a unit load or structure. These tests are not written with the intention for them to be applied to agricultural stretch wrapping films and its application.1.1 This guide covers testing of mechanical properties of stretch wrapping films as they have been applied by a stretch wrapper to a unit load or test structure. This guide may be applied to hand-wrapping or to machine-wrapping applications. These tests may be applied to real-world or “field” testing or may be applied to theoretical or “laboratory” testing. This testing does not cover the testing of mechanical properties independent of application by stretch wrapper.1.2 No statement is made about either precision or bias of any of these test methods since results merely state whether this is in conformation to the criteria for success specified by the user of the test method.1.2.1 The user is encouraged to establish the precision and bias for their own application.1.3 The units used in this standard are SI units (metric) with their English equivalents included following them in parentheses.1.4 These tests are not intended to be applied to agricultural stretch wrapping films and its application.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.

4.1 Defacement of paint and coating films by algal growth is a common phenomenon under certain conditions. It is generally known that differences in the environment, lighting, temperature, substrate, and other factors in addition to the coating composition affect the susceptibility of a given painted surface. This test method attempts to provide a means to comparatively evaluate different coating formulations for their relative performance under a given set of conditions. It does not imply that a coating that resists growth under these conditions will necessarily resist growth in the actual application.4.2 Familiarity with microbiological techniques is required. This test method should not be used by persons without at least basic microbiological training.1.1 This test method covers an accelerated method for determining the relative resistance of a paint or coating film to algal growth.NOTE 1: It is hoped that a ranking of relative performance would be similar to that ranked from outdoor exposures. However, this test method should not be used as a replacement for exterior exposure since many other factors, only a few of which are listed will affect those results.NOTE 2: ASTM weathering standards are no longer referenced in this document, but Practices D822, D4141, D4587, D5031, and D6695 are commonly used.1.2 The values stated in SI units are to be regarded as the standard.

4.1 Defacement of paint and coating films by fungal growth (mold, mildew) is a common phenomenon, and defacement by algal growth can also occur under certain conditions. It is generally known that differences in the environment, lighting, temperature, humidity, substrate pH, and other factors in addition to the coating composition affect the susceptibility of a given painted surface. This test method attempts to provide a means to comparatively evaluate different coating formulations for their relative performance under a given set of conditions. It does not imply that a coating that resists growth under these conditions will necessarily resist growth in the actual application. The method is not intended to simulate or replace indoor or outdoor exposure of paint films or related coatings.NOTE 1: It is hoped that a ranking of relative performance would be similar to that ranked from outdoor exposures. Paint designated for service in exterior conditions should be pre-conditioned by laboratory accelerated weathering prior to exposure to fungi. All pre-conditioning must be detailed in the final report. This test method however, should not be used as a replacement for exterior exposure (that is, Practice D3456) since many other factors, only a few of which are listed will affect those results.4.2 Familiarity with microbiological techniques is required. This test method should not be used by persons without at least basic microbiological training.1.1 This test method covers an accelerated method for determining the relative resistance of two or more paints or coating films to fungal growth.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

4.1 This test method is intended for use primarily as a means of comparing the performance of unitizing films. It can also be used to compare the effectiveness of different wrap cycles with the same wrapping materials. No direct correlation between these test results and actual field performance has been established.4.2 This test method simulates mechanical handling anticipated during all distribution phases.4.3 This test method leaves open to the discretion of the user the establishment of test levels and numbers of cycles constituting the test, so that the user might tailor the test to simulate a particular distribution environment. The section on mechanical handling over 100 pounds (45 kg) in Practice D4169 may provide some guidance in this regard.1.1 This test method covers evaluation and comparison of the ability of unitizing films to survive various methods of mechanical handling.1.2 The test method described is applicable to common means of material handling, including the following: forklift, push/pull, clamp truck, crane, and spade lift-type handling systems.1.3 The test levels may be varied to reflect known levels of intensity accurately for the specific unit load under testing.1.4 The methodology of performing the mechanical handling tests is described in detail in Test Methods D6055 and Test Methods D6179. This test method will describe only sample preparation and evaluation in the special case of evaluating the performance of stretch film for load unitizing.1.5 The values stated in inch-pound units are to be regarded as standard.

This specification covers unpigmented, unsupported, sheet or tubular, medium-density polyethylene films intended for general uses and packaging applications. The film shall be made from homopolymer polyethylene, copolymer polyethylene commonly referred to as low-pressure polyethylene, or blends of homopolymers and copolymers that include ethylene/vinyl-acetate copolymers. The specimens shall be conditioned before testing in the standard laboratory temperature. Tests shall be conducted to determine the physical properties of the specimens which shall conform to the following physical requirements: secant modulus or stiffness; kinetic coefficient of friction; optical properties such as clarity, gloss, and haze; surface treatment level or wetting tension; impact resistance; tensile strength and elongation at break; heat sealability; and odor level.1.1 This specification covers unpigmented, unsupported, sheet or tubular, medium-density polyethylene films (hereafter referred to as film or films) from resins having densities in the range from 926.0 to 938.0 kg/m3 (0.926 to 0.938 g/cm3), inclusive, as measured on molded plaques.1.2 This specification is applicable to homopolymer polyethylene but is not restricted to it.1.3 This specification is also applicable to films made from copolymer polyethylene commonly referred to in industry as low-pressure polyethylene.1.4 This specification is also applicable to films made from blends of homopolymers and copolymers, including ethylene/vinyl-acetate copolymers.1.5 This specification allows for the use of recycled polyethylene film or resin as feedstock, in whole or in part, as long as all the requirements of this specification are met and as long as any specific requirements as governed by the producer and end user are also met (see Note 1).NOTE 1: Guide D7209 contains terminology and definitions relating to recycled plastics.1.6 Special care must be exercised if this specification is applied to colored or pigmented films. This specification does not address specific problems associated with coloring, such as, quantity and quality of pigment dispersion, optical properties, and increase in density. These and other areas must be taken into account by mutual agreement between the supplier and the purchaser.1.7 The thickness of the films covered by this specification range from 25 to 100 μm (0.001 to 0.004 in.), inclusive. The maximum width of the sheet or lay-flat is 3.05 m (120 in.).1.8 This specification does not cover oriented heat-shrinkable films.1.9 This specification defines the levels of various physical properties from which specifications for specific films are to be described. The levels of physical properties required by a film for a given application are selected from Section 6 and the corresponding tables. However, Sections 7.2 – 7.5 relating to tolerances shall apply without change to all film falling within the scope indicated by the title and 1.1 – 1.4.1.10 This specification covers dimensional tolerances, classification, intrinsic quality requirements, and test methods. The dimensional tolerances include thickness, width, and length or yield. Classification defines types, classes, surfaces, and finishes. The intrinsic quality requirements include density, workmanship, impact strength, tensile strength, heat sealability, and odor, as well as the classification properties for stiffness, coefficient of friction, optical properties, and surface treatment. A sampling method is included.1.11 The values stated in SI units are to be regarded as standard. The values in parentheses are given for information only.1.12 The following precautionary caveat pertains only to the test methods portion, Section 10, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use.

This test method covers the measurement of the sheet resistance of metallic thin films with a collinear four-probe array. It is intended for use with rectangular metallic films formed by deposition of a material or by a thinning process and supported by an insulating substrate. This test method is suitable for referee measurement purposes as well as for routine acceptance measurements. A collinear four-probe array is used to determine the sheet resistance by passing a measured direct current through the specimen between the outer probes and measuring the resulting potential difference between the inner probes. The sheet resistance is calculated from the measured current and potential values using correction factors associated with the geometry of the specimen and the probe spacing. The accuracy of the electrical measuring equipment is tested by means of an analog circuit containing a known standard resistor together with other resistors which simulate the resistance at the contacts between the probe tips and the film surface.1.1 This test method covers the measurement of the sheet resistance of metallic thin films with a collinear four-probe array. It is intended for use with rectangular metallic films between 0.01 and 100 [mu]m thick, formed by deposition of a material or by a thinning process and supported by an insulating substrate, in the sheet resistance range from 10 to 10 [omega]/[open-box] (see 3.1.3). 1.2 This test method is suitable for referee measurement purposes as well as for routine acceptance measurements. 1.3 The values stated in Si units are to be regarded as the standard. The values given in parentheses are for information only. 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 and health practices and determine the applicability of regulatory limitations prior to use.

5.1 The levels of tensile properties obtained when testing high performance polyethylene films are dependent on the age and history of the specimen and on the specific conditions used during the test. Among these conditions are rate of stretching, type of clamps, gauge length of specimen, temperature and humidity of the atmosphere, rate of airflow across the specimen, and temperature and moisture content of the specimen. Testing conditions accordingly are specified precisely to obtain reproducible test results on a specific sample.5.2 Breaking force is used in engineering calculations when designing various types of products. When needed to compare intrinsic strength characteristics, films of different sizes or different types of film, breaking tenacity is very useful because, for a given type of film, breaking force is approximately proportional to linear density.5.3 Elongation of film is taken into consideration in the design and engineering of reinforced products because of its effect on uniformity of the finished product and its dimensional stability during service.5.4 The FASE is used to monitor changes in characteristics of the material during the various stages involved in the processing.5.5 Modulus is a measure of the resistance of film to extension as a force is applied. Although modulus may be determined at any specified force, initial modulus is the value most commonly used.5.6 Work-to-break is dependent on the relationship of force to elongation. It is a measure of the ability of a textile structure to absorb mechanical energy. Toughness at break is work-to-break per unit mass.5.7 Shape, size, and internal construction of the end-product can have appreciable effect on product performance. It is not possible, therefore, to evaluate the performance of end product in terms of the reinforcing material alone.5.8 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, test samples should be used that are as homogeneous as possible, that are drawn from the material from which the disparate test results were obtained, and that are randomly assigned in equal numbers to each laboratory for testing. Other materials with established test values may be used for this purpose. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias.1.1 These test methods cover the tensile testing of high performance polyethylene films. The methods include testing procedure only and include no specifications or tolerances.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.3 This standard includes the following test methods:  SectionBreaking Force 11Breaking Tenacity 12Toughness at Break 17Elongation at Break 13Force at Specified Elongation (FASE) 14Linear Density 10Modulus 15Work-to-Break 161.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.
