Conditioning, Chemical and Thermal Properties
General Information
SIGNIFICANCE AND USE
5.1 Test Methods D2654, Procedure 1, is used in the trade as a basis for rejecting abnormally wet material, but it is not recommended for routine acceptance testing of commercial shipment. Procedure 2 is used by the trade and is recommended for acceptance testing of commercial shipments except as stated in Note 1 . Procedure 3 is used to determine the moisture in a material in a given moisture-equilibrium situation and is not used for acceptance testing of commercial shipments. Procedure 4 is for research and development and is recommended for determining the standard moisture regain of a material although there will usually be a bias between buyer and producer data because the produce is usually able to obtain material without surface material, mostly finishes.
5.1.1 In case of a dispute arising from differences in reported test results when using Test Method D2654 for acceptance testing of commercial shipments, the purchaser and the supplier shall conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties shall take a group of test specimens that are as homogeneous as possible and that are from a lot of material of the type in question. The test specimens shall then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories shall be compared using student's l-test for unpaired data and an acceptable probability level chosen by the two parties before the testing is begun. If a bias is found, either its cause must be found and corrected or the purchaser and the supplier must agree to interpret future test results in the light of the known bias.
5.2 The measurement of moisture is important for several reasons, including the following:
5.2.1 Large quantities of fibers and manufactured textile products containing some water are bought and sold on the basis of...
SCOPE
1.1 These test methods cover measurement of moisture in textile materials as (1) moisture content or pick-up using ambient air for oven-drying, (2) moisture content or pick-up using standard atmosphere for testing textiles for oven-drying, (3) moisture content or pick-up at moisture equilibrium, and (4) moisture regain. These test methods are applicable to all fibers natural or man-made, and in all forms from fiber or filament to finished fabric, subject to the limitations set forth in 1.1.1 through 1.1.4. Blends of fibers shall also be tested by these methods.
1.1.1 Procedure 1—This oven-drying technique, using ambient air heated to 105 °C, shall be used in any situation in which a simple and convenient method for routine process control or when in-plant evaluation is needed to determine an approximation of the moisture content or pickup. It is not recommended for jute or grease wool, or for acceptance testing in commercial transactions.
1.1.2 Procedure 2—Oven-drying technique, using air from the standard atmosphere air for testing textiles that is heated to 105 °C and other refinements in technique, shall be used as a basis for commercial transactions for all materials for which it is known that no significant quantity of non-aqueous volatile matter is present on, or in, the material to be tested.
Note 1: The air supply for Procedure 2 has been changed from desiccated air to the air from the standard atmosphere for testing textiles because the latter is in common use and is prescribed in Test Method D494 for commercial mass of a shipment. By agreement, however, desiccated air may be used.
1.1.3 Procedure 3—This oven-drying technique uses specimens in moisture-equilibrium under specified conditions and an oven with an air supply of specified temperature and relative humidity heated to 105 °C, and other refinements in technique. The procedure is used to determine the moisture content or pickup of a material i...

SIGNIFICANCE AND USE
5.1 This test method measures the rate of thermal transport between a heating element and a fabric specimen. Some of the comfort properties of a garment relate to initial thermal sensations (that is, cold or warm feeling upon initial contact), where lower thermal effusivity values indicate sensations of warmth and higher values indicate sensations of coolness. The thermal effusivity of different fabrics and their initial perceived surface temperature are important to assist product developers with fabric selection.
5.2 The sensor and the test specimen being measured shall be at the same temperature for measurements at standard conditions. This test method may be applied to any fabric with a thermal effusivity in the range of 35 to 1700 Ws1/2/m2·K.
5.3 Air flow shall be kept at a minimum to ensure temperature fluctuations do not occur during the measurement.
SCOPE
1.1 This test method covers the quantitative measurement of thermal effusivity of woven, knitted, or non-woven fabrics using a guarded modified transient plane source (MTPS) instrument.4 This test method is applicable to a wide range of thicknesses; however, the thickness of the specimen must be greater than the penetration depth of the heat flux during the measurement time.
1.2 This test method is comparative since specimens of known thermal effusivity are used to calibrate the apparatus at the factory level. Thermal effusivity of the calibration specimens are confirmed through calculations that use established properties of thermal conductivity, density, and specific heat.
1.3 This test method is intended for measuring fabrics in a dry state at ambient conditions.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.

5.2 This test method is used for the determination of the amounts of naturally present oily or waxy impurities that have not been completely removed from textiles made from animal fibers, and for the determination of the amounts of oily or waxy finishing materials applied to raw materials or textiles during manufacture. See 3.1.1, extractable matter.
5.3 The test method may be used as a step in the determination of the commercial weight of fiber, yarn, and textile shipments.
5.4 The International Wool Textile Organization specifies the use of a halogenated hydrocarbon, dichloromethane, also called methylene chloride (CH2Cl2) instead of the solvent specified in this test method (IWTO-10-62(E)).
5.5 Extractables by mass loss is frequently used for textiles which have a relatively large amount of extractable material to effect a significant mass change.
SCOPE
1.1 This test method covers a procedure for determining the extractable material on most fibers, yarns, and fabrics. Three options are included. Option 1 uses heat and Soxhlet extraction apparatus. Option 2 uses room temperature and extraction funnels. Option 3 uses either Option 1 or Option 2 extraction but provides for calculation of extractable matter from the loss in mass of the material due to the extraction rather than the extractable matter residue.
Note 1: Other standards for the determination of extractable matter in textiles made of specific fibers include: Specification D541, Specification D681, and Test Method D1574.
1.1.1 The solvents for use in this method are any solvents that the party or parties concerned agreed on; such as, Halogenated Hydrocarbon (HH) chloroform, tetrachloroethane, alcohol (isopropyl or methyl).
1.1.2 This test method may not extract cross-linked finishes or resins which may be on the textile.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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. See Sections 6 and 7.

ABSTRACT
This practice covers the conditioning and testing of textiles in those instances where such conditioning is specified in a test method. Because prior exposure of textiles to high or low humidity may affect the equilibrium moisture pick-up, a procedure also is given for preconditioning the material when specified. The equipments to be used in the conditioning and testing of textiles shall include conditioning room or chamber, psychrometer ventilated by aspiration, preconditioning cabinet, room, or suitable container, balance, and multiple shelf conditioning rack. The conditioning room or chamber shall consist of equipment for maintaining the standard atmosphere for testing textiles throughout the room or chamber within the tolerances given and including facilities for circulating air over all surfaces of the exposed sample or specimen and equipment for recording the temperature and relative humidity of the air in the conditioning room or chamber. Samples or specimens requiring preconditioning shall be brought to a relatively low moisture content in a specified atmosphere. Samples or specimens requiring conditioning shall be brought to moisture equilibrium for testing in the standard atmosphere for testing textiles, or when required.

SIGNIFICANCE AND USE
5.1 Either of these two test methods is used to determine the temperature at which a synthetic fiber specimen changes from a solid to a liquid-like state.
5.1.1 Synthetic fibers may be either amorphous or semi-crystalline thermoplastics or thermosets. Synthetic fibers may change from the solid to a liquid-like state on heating because of the glass transition of amorphous polymers, the melting of crystalline regions of semi-crystalline polymers, or at the onset of degradation. Thermoplastic fibers consist of crystalline and amorphous regions and may be manufactured with a range of molecular weights. The amorphous and crystalline fiber structure and variable molecular weight can lead to a melting temperature range instead of a discreet melting point (see Table X1.1).
5.2 This test method is considered satisfactory for acceptance testing of commercial shipments.
5.2.1 If there are differences of practical significance between reported test results for two or more laboratories, perform comparative testing to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, use the samples for such a comparative test that are as homogeneous as possible, drawn from the same lot of material as the samples that resulted in disparate results during initial testing and randomly assigned in equal numbers to each laboratory. Compare the test results from the laboratories involved using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias.
5.3 This test method is suitable for quality control testing of synthetic fibers and product comparisons of different fibers by manufacturers, retailers, and users.
5.4 If the test method is used to identify fiber material type, it is important to test a known reference material at the s...
SCOPE
1.1 Either of two test methods are used to determine the melting temperature of thermoplastic fibers, yarns, or threads.
1.2 Method 1 can be used to determine melting temperatures for blends of multiple fiber material types. Method 2 can only be used to determine the melting temperature of a single fiber material type.
1.2.1 Method 1, Differential Scanning Calorimetry (DSC), measures changes in heat capacity and will detect the glass transition, the crystalline melting and endothermic thermal degradation.
1.2.2 Method 2, a visual determination of melting, determines any change that visually appears as a transition from a solid to a liquid state.
1.2.3 Due to the differences in what each test method measures, the results from Method 1 and Method 2 cannot be compared.
1.3 The values stated in either SI units or other units are to be regarded separately. The values stated in each system are not exact equivalents; therefore, each system shall be used independently without combining values.
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.

SIGNIFICANCE AND USE
The thermal resistance of a batting or batting/fabric system is of considerable importance in determining its suitability for use in fabricating cold weather protective clothing, sleeping bags, and bedding systems. The thermal interchange between man and his environment is, however, an extremely complicated subject which involves many factors in addition to the insulation values of fabrics and battings. Therefore, measured thermal insulation values can only indicate relative merit of a particular material.
SCOPE
1.1 This test method covers the measurement of the thermal resistance, under steady-state conditions, of battings and batting/fabric systems, and other materials within the limits specified in 1.2. It measures the heat transfer from a warm, dry, constant-temperature, horizontal flat-plate up through a layer of the test material to a cool atmosphere and calculates the resistance of the material. The measurements are made under still air conditions (Option #1) or with a horizontal air flow over the specimen (Option #2).
1.2 For practical purposes, this test method is limited to determinations on specimens of battings and layered batting/fabric assemblies having an intrinsic thermal resistance from 0.1 to 1.5 K·m2/W and thicknesses not in excess of 50 mm.
1.3 This test method also provides a method for determining the bulk density of the material, the insulation per unit thickness, and the insulation per unit weight.
1.4 The values stated in SI units are to be regarded as standard.
1.5 This standard does not purport to address the safety concerns associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
These test methods are a generally reliable means of identifying the generic types of fibers present in a sample of textile material of unknown composition. The methods are generally not useful for distinguishing fibers of the same generic class from different manufacturers or for distinguishing different fiber types of the same generic class from one producer.
Many fibers are chemically modified by their producers in various ways so as to alter their properties. It is possible for such modifications to interfere seriously with the analyses used in these test methods. Considerable experience and diligence of the analyst may be necessary to resolve satisfactorily these difficulties.
Dyes, lubricants, and delustrants are not present normally in amounts large enough to interfere with the analyses.
These test methods are not recommended for acceptance testing of commercial shipments because of the qualitative nature of the results and because of the limitations previously noted.
Note 2—For statements on precision and bias of the standard quantitative test methods for determining physical properties for confirmation of fiber identification refer to the cited test method. The precision and bias of the nonstandard quantitative test methods described are strongly influenced by the skill of the operator. The limited use of the test methods for qualitative identification cannot justify the effort that would be necessary to determine the precision and bias of the techniques.
SCOPE
1.1 These test methods cover the identification of the following textile fibers used commercially in the United States:

1.2 Man-made fibers are listed in 1.1 under the generic names approved by the Federal Trade Commission and listed in Terminology D 123, Annex A1 (except for fluorocarbon and polycarbonate). Many of the generic classes of man-made fibers are produced by several manufacturers and sold under various trademark names as follows (Note 1):

Additional information on fiber types and trademarks is given in References (1, 2, and 3).
1.3 Most manufacturers offer a variety of fiber types of a specific generic class. Differences in tenacity, linear density, bulkiness, or the presence of inert delustrants normally do not interfere with analytic tests, but chemical modifications (for such purposes as increased dyeability with certain dyestuffs) may affect the infrared spec...

SIGNIFICANCE AND USE
Test Methods D 629 for the determination of quantitative analysis of textiles may be used for acceptance testing of commercial shipments but caution is advised since information on between-laboratory precision is lacking. Comparative tests as directed in 5.1.1 or by Table D 1909 may be advisable.
In case of a dispute arising from differences in reported test results using Test Methods D 629 for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and which are from a lot of material of the type in question. The test specimen should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student's t-test and an acceptable probability level chosen by the two parties before the testing began. If a bias is found, either its cause must be found and corrected or the purchaser and supplier must agree to interpret future test results in the light of the known bias.
The effects of the various reagents used in the chemical methods on the residual fibers in a blend depend upon the history of the fibers and, unless otherwise stated, are generally too small or too uncertain to warrant the application of correction factors.
Fiber composition is generally expressed either on the oven-dry mass of the original sample or the oven-dry mass of the clean fiber after the removal of nonfibrous materials. If nonfibrous materials are not first removed from the textile before the fiber analysis is carried out, or if the treatments described in Section 8 are incapable of removing them, any such materials present will increase the percentage of the fiber constituent with which they are removed ...
SCOPE
1.1 These test methods cover procedures for the determination of the fiber blend composition of mixtures of the fibers listed in 1.2. Procedures for quantitative estimation of the amount of moisture and certain nonfibrous materials in textiles are also described, for use in the analysis of mixtures, but these are not the primary methods for the determination of moisture content for commercial weights.

Samples or specimens requiring preconditioning shall be brought to a relatively low moisture content in a specified atmosphere. Samples or specimens requiring conditioning shall be brought to moisture equilibrium for testing in the standard atmosphere for testing textiles, or when required.
SCOPE
1.1 This practice covers the conditioning and testing of textiles when conditioning is specified in a test method. Because prior exposure of textiles to high or low humidity may affect moisture pick-up equilibrium, a procedure also is given for preconditioning the material when required.
1.2 The values stated the text are in SI units. Inch-pound units are shown in parentheses. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance to a specification.

SIGNIFICANCE AND USE
Either of these two test methods is used to determine the temperature at which a synthetic fiber specimen changes from a solid to a liquid-like state.
Synthetic fibers may be either amorphous or semi-crystalline thermoplastics or thermosets. Synthetic fibers may change from the solid to a liquid-like state on heating because of the glass transition of amorphous polymers, the melting of crystalline regions of semi-crystalline polymers, or at the onset of degradation. Thermoplastic fibers consist of crystalline and amorphous regions and may be manufactured with a range of molecular weights. The amorphous and crystalline fiber structure and variable molecular weight can lead to a melting temperature range instead of a discreet melting point (see Table X1.1).
This test method is considered satisfactory for acceptance testing of commercial shipments.
If there are differences of practical significance between reported test results for two or more laboratories, perform comparative testing to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, use the samples for such a comparative test that are as homogeneous as possible, drawn from the same lot of material as the samples that resulted in disparate results during initial testing and randomly assigned in equal numbers to each laboratory. Compare the test results from the laboratories involved using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias.
This test method is suitable for quality control testing of synthetic fibers and product comparisons of different fibers by manufacturers, retailers, and users.
If the test method is used to identify fiber material type, it is important to test a known reference material at the same laboratory with the same ...
SCOPE
1.1 Either of two test methods are used to determine the melting temperature of thermoplastic fibers, yarns, or threads.
1.2 Method 1 can be used to determine melting temperatures for blends of multiple fiber material types. Method 2 can only be used to determine the melting temperature of a single fiber material type.
1.2.1 Method 1, Differential Scanning Calorimetry (DSC), measures changes in heat capacity and will detect the glass transition, the crystalline melting and endothermic thermal degradation.
1.2.2 Method 2, a visual determination of melting, determines any change that visually appears as a transition from a solid to a liquid state.
1.2.3 Due to the differences in what each test method measures, the results from Method 1 and Method 2 cannot be compared.
1.3 The values stated in either SI units or other units are to be regarded separately. The values stated in each system are not exact equivalents; therefore, each system shall be used independently without combining values.
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.

SIGNIFICANCE AND USE
This test method may be used for acceptance testing of commercial shipments.
5.1.1 In case of a dispute arising from differences in reported test results using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between the laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and which are from a lot of material of the type in question. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using appropriate statistical analysis and a probability level chosen by the two parties before the testing begins. If a bias is found, either its cause must be found and corrected, or the purchaser and supplier must agree to interpret future test results with consideration to the known bias.
This test method is used for the determination of the amounts of naturally present oily or waxy impurities that have not been completely removed from textiles made from animal fibers, and for the determination of the amounts of oily or waxy finishing materials applied to raw materials or textiles during manufacture. See 3.1.1, extractable matter.
The test method may be used as a step in the determination of the commercial weight of fiber, yarn, and textile shipments.
The International Wool Textile Organization specifies the use of a halogenated hydrocarbon, dichloromethane, also called methylene chloride (CH2Cl2) instead of the solvent specified in this test method (IWTO-10-62(E)).
Extractables by mass loss is frequently used for textiles which have a relatively large amount of extractable material to effect a significant mass change.
SCOPE
1.1 This test method covers a procedure for determining the extractable material on most fibers, yarns, and fabrics. Three options are included. Option 1 uses heat and Soxhlet extraction apparatus. Option 2 uses room temperature and extraction funnels. Option 3 uses either Option 1 or Option 2 extraction but provides for calculation of extractable matter from the loss in mass of the material due to the extraction rather than the extractable matter residue.
Note 1
Other standards for the determination of extractable matter in textiles made of specific fibers include: Specification D 541, Specification D 681, and Test Method D 1574.
1.1.1 The solvents for use in this method are any solvents that the party or parties concerned agreed on; such as, Halogenated Hydrocarbon (HH) chloroform, tetrachloroethane, alcohol.
1.1.2 This test method may not extract cross-linked finishes or resins which may be on the textile.
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.

ABSTRACT
This practice covers the conditioning and testing of textiles in those instances where such conditioning is specified in a test method. Because prior exposure of textiles to high or low humidity may affect the equilibrium moisture pick-up, a procedure also is given for preconditioning the material when specified.

The conditioning room or chamber shall consist of equipment for maintaining the standard atmosphere for testing textiles throughout the room or chamber within the tolerances given and including facilities for circulating air over all surfaces of the exposed sample or specimen and equipment for recording the temperature and relative humidity of the air in the conditioning room or chamber. Samples or specimens requiring preconditioning shall be brought to a relatively low moisture content in a specified atmosphere.

SIGNIFICANCE AND USE
These test methods are a generally reliable means of identifying the generic types of fibers present in a sample of textile material of unknown composition. The methods are generally not useful for distinguishing fibers of the same generic class from different manufacturers or for distinguishing different fiber types of the same generic class from one producer.
Many fibers are chemically modified by their producers in various ways so as to alter their properties. It is possible for such modifications to interfere seriously with the analyses used in these test methods. Considerable experience and diligence of the analyst may be necessary to resolve satisfactorily these difficulties.
Dyes, lubricants, and delustrants are not present normally in amounts large enough to interfere with the analyses.
These test methods are not recommended for acceptance testing of commercial shipments because of the qualitative nature of the results and because of the limitations previously noted.
Note 2—For statements on precision and bias of the standard quantitative test methods for determining physical properties for confirmation of fiber identification refer to the cited test method. The precision and bias of the nonstandard quantitative test methods described are strongly influenced by the skill of the operator. The limited use of the test methods for qualitative identification cannot justify the effort that would be necessary to determine the precision and bias of the techniques.

1.3 Most manufacturers offer a variety of fiber types of a specific generic class. Differences in tenacity, linear density, bulkiness, or the presence of inert delustrants normally do not interfere with analytic tests, but chemical modifications (for such purposes as increased dyeability with certain dyestuffs) may affect the infrared spectra and some of the physical properties, particularly the melting point. Many generic classes of fibers are sold with a variety of cross-se...

SIGNIFICANCE AND USE
4.1 The thermal resistance of a batting or batting/fabric system is of considerable importance in determining its suitability for use in fabricating cold weather protective clothing, sleeping bags, and bedding systems. The thermal interchange between man and his environment is, however, an extremely complicated subject which involves many factors in addition to the insulation values of fabrics and battings. Therefore, measured thermal insulation values can only indicate relative merit of a particular material.
SCOPE
1.1 This test method covers the measurement of the thermal resistance, under steady-state conditions, of battings and batting/fabric systems, and other materials within the limits specified in 1.2. It measures the heat transfer from a warm, dry, constant-temperature, horizontal flat-plate up through a layer of the test material to a cool atmosphere and calculates the resistance of the material. The measurements are made under still air conditions (Option #1) or with a horizontal air flow over the specimen (Option #2).
1.2 For practical purposes, this test method is limited to determinations on specimens of battings and layered batting/fabric assemblies having an intrinsic thermal resistance from 0.1 to 1.5 K·m2/W and thicknesses not in excess of 50 mm.
1.3 This test method also provides a method for determining the bulk density of the material, the insulation per unit thickness, and the insulation per unit weight.
1.4 The values stated in SI units are to be regarded as standard.
1.5 This standard does not purport to address the safety concerns associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
This method provides for the determination of the steady state thermal resistance of a fabric or layers of fabrics and for the determination of the temperature regulating factor (TRF) as defined below. This test method is considered satisfactory for acceptance testing of commercial shipments because the round robin testing shows high precision and no bias for testing of textile fabrics and foams.
5.1.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative test should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, use the samples for such a comparative test that are as homogeneous as possible, drawn from the same lot of material as the samples that resulted in disparate results during initial testing and randomly assigned in equal numbers to each laboratory. The test results from the laboratories involved should be compared using a statistical test for unpaired data, a probability level chosen prior to the testing series. If bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias.
This test method is useful in quality and cost control during manufacture. It can be used to establish criteria for establishing thermal and comfort parameters for textiles particularly used in the clothing industry.
SCOPE
1.1 This test method covers the determination of the overall thermal transmission coefficient due to conduction for dry specimens of textile fabrics, battings, and other materials and the determination of the temperature regulating factor (TRF) defined below.
1.2 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.
WITHDRAWN RATIONALE
This test method covers the determination of the overall thermal transmission coefficient due to conduction for dry specimens of textile fabrics, battings, and other materials and the determination of the temperature regulating factor (TRF) defined below.
Formerly under the jurisdiction of Committee D13 on Textiles, this test method was withdrawn in March 2013 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
