5.1 The expanded limits of the Adjunct for VCF are defined in a mixture of terms of customary and metric units. Table 1 shows the defining limits and their associated units in bold italics. Also shown in Table 1 are the limits converted to their equivalent units (and, in the case of the densities, other base temperatures).5.2 Note that only the precision levels of the defining values shown in Table 1 are correct. The other values showing converted units have been rounded to the significant digits shown; as rounded values, they may numerically fall just outside of the actual limits established by the defining values.5.3 Table 2 provides a cross-reference between the historical table designations and the corresponding section in the Adjunct for VCF. Note that procedure paragraphs 11.1.6.3 (U.S. customary units) and 11.1.7.3 (metric units) provide methods for correcting on-line density measurements from live conditions to base conditions and then to compute CTPL factors for continuous volume corrections to base conditions.5.4 When a glass hydrometer is used to measure the density of a liquid, special corrections must be made to account for the thermal expansion of the glass when the temperature is different from that at which the hydrometer was calibrated. The 1980 CTL Tables had generalized equations to correct glass hydrometer readings, and these corrections were part of the printed odd-numbered tables. However, detailed procedures to correct a glass hydrometer reading are beyond the scope of the Adjunct for VCF. The user should refer to the appropriate sections of API MPMS Chapter 9 or other appropriate density/hydrometer standards for guidance.5.5 The set of correlations given in the Adjunct for VCF is intended for use with petroleum fluids comprising either crude oils, refined products, or lubricating oils that are single-phase liquids under normal operating conditions. The liquid classifications listed here are typical terms used in the industry, but local nomenclature may vary. The list is illustrative and is not meant to be all-inclusive.5.6 Crude Oils—A crude oil is considered to conform to the commodity group Generalized Crude Oils if its density falls in the range between approximately –10°API to 100°API. Crude oils that have been stabilized for transportation or storage purposes and whose API gravities lie within that range are considered to be part of the Crude Oil group. Also, aviation Jet B (JP-4) is best represented by the Crude Oil correlation.5.7 Refined Products—A refined product is considered to conform to the commodity group of Generalized Refined Products if the fluid falls within one of the refined product groups. Note the product descriptors are generalizations. The commercial specification ranges of some products may place their densities partly within an adjacent class (for example, a low-density diesel may lie in the jet fuel class). In such cases, the product should be allocated to the class appropriate to its density, not its descriptor. The groups are defined as follows:5.7.1 Gasoline—Motor gasoline and unfinished gasoline blending stock with a base density range between approximately 50°API and 85°API. This group includes substances with the commercial identification of: premium gasoline, unleaded gasoline, motor spirit, clear gasoline, low-lead gas, motor gasoline, catalyst gas, alkylate, catalytic cracked gasoline, naphtha, reformulated gasoline, and aviation gasoline.5.7.2 Jet Fuels—Jet fuels, kerosene, and Stoddard solvents with a base density range between approximately 37°API and 50°API. This group includes substances with the commercial identification of: aviation kerosene K1 and K2, aviation Jet A and A-1, kerosene, Stoddard solvent, JP-5, and JP-8.5.7.3 Fuel Oils—Diesel oils, heating oils, and fuel oils with a base density range between approximately –10°API and 37°API. This group includes substances with the commercial identification of: No. 6 fuel oil, fuel oil PA, low-sulfur fuel oil, LT (low temperature) fuel oil, fuel oil, fuel oils LLS (light low sulfur), No. 2 furnace oil, furnace oil, auto diesel, gas oil, No. 2 burner fuel, diesel fuel, heating oil, and premium diesel.5.8 Lubricating Oils—A lubricating oil is considered to conform to the commodity group Generalized Lubricating Oils if it is a base stock derived from crude oil fractions by distillation or asphalt precipitation. For the purpose of the Adjunct for VCF, lubricating oils have initial boiling points greater than 700 °F (370 °C) and densities in the range between approximately –10°API to 45°API.5.9 Special Applications—Liquids that are assigned the special applications category are generally relatively pure products or homogeneous mixtures with stable (unchanging) chemical composition that are derived from petroleum (or are petroleum-based with minor proportions of other constituents) and have been tested to establish a specific thermal expansion factor for the particular fluid. These tables should be considered for use when:5.9.1 The generalized commodity groups' parameters are suspected of not adequately representing the thermal expansion properties of the liquid.5.9.2 A precise thermal expansion coefficient can be determined by experiment. A minimum of ten temperature/density data points is recommended to use this method. See 11.1.5.2 of the Adjunct for VCF for the procedure to calculate the thermal expansion coefficient from measured density data.5.9.3 Buyer and seller agree that, for their purpose, a greater degree of equity can be obtained using factors specifically measured for the liquid involved in the transaction.5.10 Refer to paragraphs 11.1.2.4 and 11.1.2.5 in the Adjunct for VCF for a complete description of the suitability of the implementation procedures for specific hydrocarbon liquids.1.1 This guide provides information related to the algorithm and implementation procedure but does not contain the full set of algorithms. The algorithms, instructions, procedures, and examples are located in the associated supplementary adjuncts. The Adjunct for Volume Correction Factors (VCF) for temperature and pressure volume correction factors for generalized crude oils, refined products, and lubricating oils provides the algorithm and implementation procedure for the correction of temperature and pressure effects on density and volume of liquid hydrocarbons. Natural gas liquids (NGLs) and liquefied petroleum gases (LPGs) are excluded from consideration in this standard but may be found in API MPMS Chapter 11.2.4/GPA 8217 Temperature Correction for NGL and LPG. As this Adjunct for VCF will be applied to a variety of applications, the output parameters of CTL, Fp, CPL, and CTPL may be used as specified in other standards.1.2 Including the pressure correction in the Adjunct for VCF represents an important change from the “temperature only” correction factors given in the 1980 Petroleum Measurement Tables. However, if the pressure is one atmosphere (the standard pressure), then there is no pressure correction and the standard/adjunct(s) will give CTL values consistent with the 1980 Petroleum Measurement Tables.1.3 The Adjunct for VCF covers general procedures for the conversion of input data to generate CTL, Fp, CPL, and CTPL values at the user-specified base temperature and pressure (Tb, Pb). Two sets of procedures are included for computing volume correction factor: one set for data expressed in customary units (temperature in °F, pressure in psig); the other for the metric system of units (temperature in °C, pressure in kPa or bar).NOTE 1: In contrast to the 1980 Petroleum Measurement Tables, the metric procedures require the procedure for customary units be used first to compute density at 60 °F. This value is then further corrected to give the metric output. The metric procedures now incorporate the base temperature of 20 °C in addition to 15 °C.1.4 The procedures in the Adjunct for VCF recognize three distinct commodity groups: crude oil, refined products, and lubricating oils. A procedure is also provided for determining volume correction for special applications where the generalized commodity groups’ parameters may not adequately represent the thermal expansion properties of the liquid and a precise thermal expansion coefficient has been determined by experiment. Procedures for determining Volume Correction Factors (VCF) for Denatured Ethanol can be found in API MPMS Chapter 11.3.3, Miscellaneous Hydrocarbon Properties—Denatured Ethanol Density and Volume Correction Factors, 3rd edition. Procedures for determining Volume Correction Factors (VCF) for Gasoline and Denatured Ethanol Blends can be found in API MPMS Chapter 11.3.4, Miscellaneous Hydrocarbon Properties—Denatured Ethanol and Gasoline Component Blend Densities and Volume Correction Factors, 1st edition.1.5 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.1.6 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.

4.1 This test method is useful for establishing any effects that a joint restraint product has on the performance of PVC pressure pipe. This test method is designed so that success in all three parts of the test provides reasonable assurance that a joint restraint product may be used on PVC pipe at the full pressure rating and capacity of the pipe.4.2 Restrained joint test specimens shall be subjected to internal pressures that are equal to the minimum burst pressure requirements for the pipe alone. The minimum burst pressure requirements for some common dimension ratios are shown in Table 1. The minimum burst pressures for other dimension ratios of pipe produced from 12454 PVC Compound (that is, pipe conforming to Specification D1785) may be determined based on a hoop stress of 6400 psi (44.13 MPa).(A) The pressures listed approximate a hoop stress of 6400 psi (44.13 MPa). Some minor adjustments have been made to keep the test pressures uniform in order to simplify testing.4.3 Testing of restrained joint test specimens for 1000 h at the sustained pressure requirements indicates any tendency of the restraint to fail in the long term. The minimum sustained pressure requirements for some common dimension ratios are shown in Table 2. The minimum sustained pressure for other dimension ratios of pipe produced from 12454 PVC Compound (for example, pipe conforming to Specification D1785) may be determined based on a hoop stress of 4200 psi (28.96 MPa).(A) The pressures listed approximate a hoop stress of 4200 psi (28.96 MPa). Some minor adjustments have been made to keep the test pressures uniform in order to simplify testing.4.4 A cyclic surge pressure test of restrained joint test specimens determines the effect of the joint restraint product on the cyclic fatigue life of PVC pipe. This test method provides a means for quickly identifying any reduction in performance that might result from the combination of the joint restraint product and the pipe. The peak hoop stress shall be determined for the pipe based on the Vinson equation for a period of 1 000 000 cycles. The base pressure shall be one half of the peak pressure. The peak pressure requirements for some common dimension ratios are shown in Table 3. The peak pressure for other dimension ratios for pipe produced from 12454 PVC Compound (for example, pipe conforming to Specification D1785) may be determined based on a hoop stress of 1587 psi (10.94 MPa).(A) The peak pressures listed approximate a peak hoop stress of 1587 psi (10.94 MPa).AbstractThis test method describes a procedure for qualifying the performance of joint restraint products for use on PVC pressure pipe systems by evaluating the effect of the joint restraint product on the performance characteristics of PVC pipe during cyclic pressure tests and static pressure tests. This test method is useful for establishing any effects that a joint restraint product has on the performance of PVC pressure pipe. This test method is designed so that success in all three parts of the test provides reasonable assurance that a joint restraint product may be used on PVC pipe at the full pressure rating and capacity of the pipe. Pipe specimen length, minimum burst pressure test, sustained pressure test, and cyclic surge pressure test shall be performed to conform with the specified requirements.1.1 This test method describes a procedure for qualifying the performance of joint restraint products for use on PVC pressure pipe systems by evaluating the effect of the joint restraint product on the performance characteristics of PVC pipe during cyclic pressure tests and static pressure tests. The PVC pipe property values referenced in this test method are for the 12454 compound as described in Specification D1784 and a 4,000 HDB shall be obtained by categorizing the LTHS in accordance with Table 1 in Test Method D2837. That includes, but is not limited to, pipe produced in accordance with the following standards: Specifications D1785 and D2241, and AWWA C900.1.2 This test method determines the short-term performance of a joint restraint product on PVC pipe, which involves the testing of restrained joint test sections to the minimum burst pressure requirements of the pipe to determine quick burst performance.1.3 This test method determines the long-term effect of a joint restraint product on PVC pipe, which involves the testing of restrained joint test sections to the sustained pressure requirements of the pipe for a period of 1000 h.1.4 This test method addresses restraint products that are rated at the full pressure capacity of the PVC pipe on which they are used. There are joint restraint devices available that are not rated at the full pressure capacity of the pipe. While those products have proven acceptable and useful in the marketplace, this test method does not apply to those products.1.5 This test method determines the performance of a joint restraint product on PVC pipe subjected to cyclic pressure surges. The performance is compared to the baseline performance of pipe without joint restraint products established by Herbert W. Vinson.21.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 This test method evaluates the following under the specified test conditions:5.1.1 The ability of a test specimen to undergo movement without reducing its fire resistance rating, and5.1.2 The duration for which a test specimen will contain a fire and retain its integrity during a predetermined fire resistive test exposure.5.2 This test method provides for the following measurements and evaluations where applicable:5.2.1 Ability of the test specimen to movement cycle.5.2.2 Ability of the test specimen to prohibit the passage of flames and hot gases.5.2.3 Transmission of heat through the test specimen.5.2.4 Ability of the test specimen to resist the passage of water during a hose stream test.5.3 This test method does not provide the following:5.3.1 Any information about the rated wall assembly because its performance has already been determined.5.3.2 Evaluation of the degree by which the test specimen contributes to the fire hazard by generation of smoke, toxic gases, or other products of combustion.5.3.3 Measurement of the degree of control or limitation of the passage of smoke or products of combustion through the test specimen.5.3.4 Measurement of flame spread over the surface of the test specimen.NOTE 3: The information in 5.3.1 – 5.3.4 may be determined by other suitable fire resistive test methods. For example, 5.3.4 may be determined by Test Method E84.5.4 In this procedure, the test specimens are subjected to one or more specific tests under laboratory conditions. When different test conditions are substituted or the end-use conditions are changed, it is not always possible by, or from, this test method to predict changes to the characteristics measured. Therefore, the results are valid only for the exposure conditions described in this test method.1.1 This fire-test-response test method measures the performance of a unique fire resistive joint system called a continuity head-of-wall joint system, which is designed to be used between a rated wall assembly and a nonrated horizontal assembly during a fire resistance test.1.2 This fire-test-response standard does not measure the performance of the rated wall assembly or the nonrated horizontal assembly.NOTE 1: Typically, rated wall assemblies obtain a fire resistance rating after being tested to Test Method E119, UL 263, CAN/ULC-S101, or other similar fire resistance test methods.1.3 This fire-test-response standard is not intended to evaluate the connections between rated wall assemblies and nonrated horizontal assemblies unless part of the continuity head-of-wall joint system.1.4 The fire resistive test end point is the period of time elapsing before the first performance criteria is reached when the continuity head-of-wall joint system is subjected to one of two time-temperature fire exposures.1.5 The fire exposure conditions used are either those specified by Test Method E119 for testing assemblies to standard time-temperature exposures or Test Method E1529 for testing assemblies to rapid-temperature rise fires.1.6 This test method specifies the heating conditions, methods of test, and criteria to establish a fire resistance rating only for a continuity head-of-wall joint system.1.7 Test results establish the performance of continuity head-of-wall joint systems to maintain continuity of fire resistance of the rated wall assembly where the continuity head-of-wall joint system interfaces with a nonrated horizontal assembly during the fire-exposure period.1.8 Test results shall not be construed as having determined the continuity head-of-wall joint system, nonrated horizontal assembly and the rated wall assembly’s suitability for use after that fire exposure.1.9 This test method does not provide quantitative information about the continuity head-of-wall joint system relative to the rate of leakage of smoke or gases or both. However, it requires that such phenomena be documented and reported when describing the general behavior of continuity head-of-wall joint systems during the fire resistive test but is not part of the conditions of compliance.1.10 Potentially important factors and fire characteristics not addressed by this test method include, but are not limited to:1.10.1 The performance of the continuity head-of-wall joint system constructed with components other than those tested.1.10.2 The cyclic movement capabilities of continuity head-of-wall joint systems other than the cycling conditions tested.1.11 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.12 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.1.13 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.1.14 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.1.15 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.1.16 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 practice is intended to measure air flow through materials used to fill joints found in building construction.5.2 This practice does not purport to establish all required criteria for the selection of an air barrier assembly. Therefore, the results should be used only for comparison purposes and should not be seen as the equivalent to field installed building systems.1.1 This practice is intended to determine the air leakage rate of aerosol foam sealants as measured in a standardized jig. This practice provides a procedure for preparing the test apparatus and further describes the application of aerosol foam sealant and other joint fillers to the apparatus prior to conducting Test Method E283.1.2 This practice allows testing laboratories to quantify the air leakage rate of aerosol foam sealants or joint filling products using Test Method E283 and reporting the data in L/(s · m2) according to Practice E29.1.3 This practice is used in conjunction with Test Method E283. Although Test Method E283 is a laboratory test method used with fenestration products, individuals interested in performing field air leakage tests on installed units should reference Test Method E783 and AAMA 502.1.4 Aerosol foam sealants are used for a variety of end use applications generally intended to reduce air leakage in the building envelope.1.5 Insulating type materials also will be found suitable for evaluation with this practice.1.6 There are no other known practices or test methods that specify the preparation of the assemblies used to determine the air leakage rate of gap filling sealants, dry preformed foams or insulations.1.7 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.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 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.
