ASTM D123-23(Terminology)
Standard Terminology Relating to Textiles

SCOPE
1.1 This standard is the compilation of all terminology developed by Committee D13 on Textiles.  
1.1.1 This terminology, consists mostly of definitions, which are specific to the textile industry. Meanings of the same terms used outside the textile industry can be found in other compilations or in dictionaries of general usage.  
1.1.2 The specific D13 subcommittee (SC) which has jurisdictional responsibility for every item is the first attribution noted after the definition. The SC terminology standard in which all the terms and definitions appear is listed by number after the jurisdiction for the term. The wording of an entry cannot be changed without the approval of the subcommittee which has jurisdiction. Users of this compilation should also review the SC terminology standard listed for more details or interpretations of these terms and their use by the SC having jurisdiction.  
1.2 In addition to being a specialized dictionary, Terminology D123 is also a tool for managing the committee's terminology. This includes finding, eliminating, and preventing redundancies, that is, where two or more terms relating the same concept are defined in different words. Redundancies can also occur when one definition is used for two or more terms.  
1.3 While the review for clarity and form are the responsibility of the terminology subcommittee, the concept of managing terminology is the broad responsibility of every writer of standards, specifically the task group leader and subcommittee chairman.  
1.4 Subsequent to a listing of specific subcommittee compilations, this standard is comprised of the following sections that are listed in the order in which they appear.  
1.4.1 Alphabetical listing of terms with definitions followed by SC attribution in brackets and SC terminology standard.  
1.4.2 Annex A1 Terms Relating to the Hand of Fabrics.  
1.4.3 Annex A2 Industry Accepted Synonyms.  
1.4.4 Annex A3 Terminology Taken From D13 Standards That Have Been Withdrawn.  
1.4.5 Annex A4 Terminology Relating to Leather.  
1.4.6 Annex A5 Terminology Revision Procedures.  
1.4.7 Appendix X1 Other Sources of Textile Terminology.  
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.

ASTM D5591-22(Test Method)
Standard Test Method for Thermal Shrinkage Force of Yarn and Cord With a Thermal Shrinkage Force Tester

SIGNIFICANCE AND USE
5.1 This test method may be used for the acceptance testing of commercial shipments of yarns and cords.  
5.1.1 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 for that material must be adjusted in consideration of the known bias.  
5.2 Experience shows that yarns or cords on would packages, usually being under tension, exhibit a contraction in length (and a resulting increase in linear density) when removed from the package and allowed to relax over a period of time at room temperature. Consequently, it they are tested without being allowed to relax, they will register higher thermal shrinkage force values as the relaxation shrinkage will be incorrectly included as the thermal shrinkage force.  
5.2.1 Retractive forces vary widely by polymer type, being almost nil within aramids and significant within most nylons. For example, the exposure of untensioned skeins of nylon yarn or cord to 95 to 100 % relative humidity at room temperature for two days and reconditioning under standard laboratory conditions will cause most of the length change that is possible at room temperature to occur within a sample. This reduction in length is accompanied by some lowering of thermal shrinkage force.  
5.3 The thermal...
SCOPE
1.1 This test method covers preparation and procedures to measure the thermal shrinkage force of yarns and cords in air.  
1.2 This test method is applicable to measurement of the thermal shrinkage force of yarns and cords whose shrinkage force at 180 ± 2 °C (355 ± 4 °F) in air does not exceed 20 N (4 lbf). This test method is applicable to nylon, polyester, and aramid yarns and cords within the applicable range of thermal shrinkage force, as well as to comparable yarns and cords from other polymers.  
1.2.1 Test specimens may be taken from yarn or cord packages, or retrieved from fabrics.  
1.3 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.  
1.4 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 hazards statements are given in Section 8.  
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.

ASTM D7785-21(Practice)
Standard Practice for Water in Lint Cotton by Oven Evaporation Combined with Volumetric Karl Fischer Titration

SIGNIFICANCE AND USE
5.1 The water content of raw or lint cotton determined by this practice, calculated from the required volume of reagent, may be greater, equal to or less than the moisture content measured by standard oven drying methods. These differences may be of significance in commercial transactions (1-3)4 (see also Appendix X2). Water content by this method is not to be considered the same attribute as moisture content.  
5.2 Standard test methods using volumetric and coulometric Karl Fischer reagent are two of the most widely used procedures for the determination of water.  
5.3 The volumetric method is typically used for the routine determination of water in the mass percent range of concentrations. If samples contain very low levels of water, the coulometric technique should be considered (see Test Methods D1533, E1064).  
5.4 This practice for testing the water content of cotton can be used for acceptance testing of commercial shipments of lint cotton, manufacturing control and calibration of fast, indirect sensors to measure water.  
5.5 Information on the water content of cotton is desirable since the physical properties of cotton are significantly affected by its water content. Variations in the amount of water present, or its regain, affect the mass and hence the market value of a lot of material.  
5.6 The observed volume of Karl Fischer reagent used in this practice to analyze a specimen represents the water in the absence of side reactions in an oven supplied with air (3).
Note 2: Side reactions in cotton that confound the actual weight loss due to water have been demonstrated in two laboratory ovens and a thermogravimetric analysis oven supplied with air (3). This results in an approximation regarding the actual amount of water in cotton based on mass loss by drying. If the moisture content by oven drying agrees with the water content measured by Karl Fischer titration, the one-to-one correspondence may be coincidental due to the presence of both negative a...
SCOPE
1.1 This practice covers the determination of the total amount of water (free and bound) in raw and lint cotton at moisture equilibrium from conditioning in the standard atmosphere for testing textiles.
Note 1: For other methods of determination of moisture in lint cotton that do not specify conditioning to moisture equilibrium, refer to Test Methods D2495 and D1348.  
1.2 This practice requires the use of oven evaporation to remove all of the water in the fiber matrix, volumetric Karl Fischer (KF) titration to determine water content and water regain, and control current potentiometry to detect the end point.  
1.3 This practice is not intended for use with potentiometric (zero current) and coulometric Karl Fischer titrators (see Test Methods D1533, D4377 and E1064), nor is this practice intended to be used with methanol extracts of cotton (See Test Methods D1348).  
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. For specific precautionary warnings see 9.1.  
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.

ASTM D1464-12(2019)(Practice)
Standard Practice for Differential Dyeing Behavior of Cotton

SIGNIFICANCE AND USE
5.1 This practice is not recommended for acceptance testing because the information obtained is qualitative rather than quantitative in nature.  
5.2 The response of fibers to the dye mixture is indicative of the uniformity of dyeing, the probability of dyeing defects due to neps, and the difficulties to be expected from heterogeneity of fibers that differ in dyeing characteristics. In general, the red dye is retained predominantly by the thick-walled fibers and the green by the thin-walled fibers.  
5.3 The color response of the specimens to the dyes in the binary mixture reflects the behavior to be expected with many other dyes. The colors from red to green may be influenced by factors such as weather during the growing period, exposure of open bolls in the field before harvest, natural color, fineness, and degree of wall development.
SCOPE
1.1 This practice covers a test for the characterization of certain dyeing behavior of cotton. This practice is especially applicable to raw cotton fibers, but may also be adapted to cotton yarns and fabrics.  
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.  
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.

Standard Practices for Visual Inspection and Grading of Fabrics Used for Inflatable Restraints

SIGNIFICANCE AND USE
5.1 These practices are suitable for incorporation in a specification. Any reference to material or cushion specification in these practices shall mean any similar agreement between the purchaser and supplier relating to the inspection and acceptance of fabric intended for inflatable restraint use.  
5.2 These practices constitute the terminology, conditions, equipment, and procedures by which rolls of inflatable restraint fabrics or cut parts are inspected and graded.  
5.3 A specification incorporating these practices may deviate from them to account for considerations of fabric property, material handling equipment, or inflatable restraint cushion design, or a combination thereof. Whenever such deviations from standard occur, they are recorded in the report.  
5.4 These practices acknowledge that, in the normal course of production, acceptable rolls of fabric will be produced containing imperfections; subsequently, pieces will be cut from the rolls and those pieces that contain imperfections restricted in Tables 1-5 will be culled at that time.  
5.5 The accuracy in the results from visually inspecting fabric using these practices is affected by the ability of the inspector to detect, identify, and evaluate the severity of an imperfection in a moving fabric or in a cut part. Such ability can be affected by visual acuity, viewing distance, fabric traverse speed, lighting conditions, inspector discipline and training, and the availability and accuracy of suitable visual aids.  
5.6 Systematic bias may result from using these practices whenever the precision or scale of the visual aids used to identify and quantify imperfections differs between the purchaser and supplier.
SCOPE
1.1 These practices cover procedures for the inspection and grading of coated and uncoated woven flat and one-piece woven (OPW) fabrics, and for the inspection and culling of cut parts made of such fabrics, all of which are used in the manufacture of inflatable restraint cushions.  
1.2 For ease of reference, the scope, summary of practice, significance and use, apparatus, sampling, procedure, and report sections are listed separately for each inspection practice.

ASTM D5822-13(2019)(Test Method)
Standard Test Method for Determining Seam Strength in Inflatable Restraint Cushions

SIGNIFICANCE AND USE
5.1 Seam strength testing is used for design validation and for lot acceptance.  
5.2 This test method constitutes the conditions, procedures, and equipment by which either seams taken from inflatable restraint cushions, or seam types that can potentially be used for inflatable restraint cushions are tested for seam strength, seam efficiency, and failure mode. It is intended to be used as a guideline in establishing a written part specification or print. The specification or agreement of purchaser and supplier may deviate from the procedures described herein when (based on experience) considerations of equipment, cushion design, or other factors dictate otherwise.  
5.3 In cases of dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should perform 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 from the same lot of fabric to be evaluated, which utilize a like seam assembly (or standard seam assembly) to achieve seam interaction. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. If a bias is found, either its cause must be determined and corrected, or the purchaser and supplier must agree to interpret future test results in light of the known bias.  
5.4 Test Method D5822 is a reliable test method but procedures which may require special attention are identified in the precision and bias section of this test method.
SCOPE
1.1 This test method covers the measurement of seam efficiency and the maximum seam strength in inflatable restraint cushions composed of woven fabrics when a force is applied perpendicular to the seam, using a grab test. For evaluating sewing thread, refer to Test Method D204.  
1.2 This test method is restricted to seams that are either obtained from an inflatable restraint cushion or prepared off-line, specifically for testing, using fabric blanks, not obtained from a previously sewn cushion assembly. Seams may include but are not limited to sewn, OPW, glued, sealed and sewn, or fused (chemically or thermally). This test method can be used for either lot testing of production cushions, or for research and development purposes.  
1.3 This test method is used when the measurement of a resistance to a specified force, a breaking force, a minimum elongation, or a combination thereof are required to determine the seam strength, or seam integrity of a particular fabric for inflatable restraint use.  
1.4 Procedures and apparatus other than those stated in this standard may be used by agreement between purchaser and supplier with the specific deviations from the standard acknowledged in the report.  
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 exact equivalents; therefore, each system must be used independently of the other.  
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.

Standard Terminology Relating to Floor Coverings and Textile Upholstered Furniture

SCOPE
1.1 This standard is a compilation of all terminology developed by Subcommittee D13.62 on Labeling and related to refurbishing or care of floor coverings and textile upholstered furniture, excluding leather. These items cannot be refurbished by the laundering and dry cleaning methods used for apparel and other domestic textile products.  
1.2 This document defines terms for the care of textile floor coverings and textile upholstered furniture. The exact care instructions and sequence of procedures are to be determined by the manufacturer.  
1.3 The recommended terminology covers common meanings used by both textile technologists and consumers.  
1.4 This terminology is not applicable to unattached fabrics, such as slipcovers, used for covering furniture.  
1.5 When care labels are provided, a standardized terminology in a logical sequence facilitates the maximum disclosure of essential information in small label space and assists understanding of recommended care practices by the consumer.  
1.6 The use of either a permanent or a nonattached care instruction should not preclude the use of the alternative as an additional source of information to the consumer.  
1.7 The term “only” in any label term limits the procedure to the stated instruction.  
1.8 This terminology is unique to the care of textile floor coverings and upholstered furniture. Meanings of the same terms outside the industry can be found in other compilations or dictionaries of general usage.  
1.9 In addition to being a specialized dictionary, Terminology D5253 is also useful for managing the subcommittee's terminology.  
1.10 Terms listed are under the jurisdiction of SC D13.62.

ASTM D629-15(Test Method)
Standard Test Methods for Quantitative Analysis of Textiles

SIGNIFICANCE AND USE
5.1 Qualitative and quantitative fiber identification is actively pursued by committee RA24 (Fiber Identification) of AATCC and presented in AATCC Test Methods 20 and 20A. Since precision and bias development is also part of the AATCC test methods, both AATCC and ASTM D13 have agreed that new development will take place in RA24. However, because there is valuable information still present in the ASTM standards, D13.51 has agreed Test MethodsD276 and D629 will be maintained as active standards by ASTM.  
5.2 Test Methods D629 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 5.2.1 or in Standard Tables D1909 may be advisable.  
5.2.1 In case of a dispute arising from differences in reported test results using Test Methods D629 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.  
5.3 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 o...
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.

ASTM D6419-00(2023)(Test Method)
Standard Test Method for Volatile Content of Sheet-Fed and Coldset Web Offset Printing Inks

SIGNIFICANCE AND USE
4.1 This test method is the procedure of choice for determining volatile content of sheet-fed and coldset web offset inks. This information is useful to the ink manufacturer and user and to environmental interests as part of the determination of the mass of volatile organic compounds emitted from the ink.
Note 3: Since these inks do not contain water or any materials currently classified by US EPA as negligibly photochemically reactive (exempt solvents), volatile organic compound content is the same as volatile content. The volatile organic compounds in these inks are high boiling hydrocarbon oils which are, according to US EPA guidelines, 95 % retained in the printed substrate or oxidized into the ink film. Therefore, the mass of volatile organic compound emitted from the ink would be calculated as only 5 % of the volatile organic compound content of the ink as derived from the results of this test method.
SCOPE
1.1 This test method describes a procedure for determination of the weight percent volatile content of sheet-fed and coldset web offset printing inks. Test specimens are heated at 110 °C ± 1 °C for 60 min.
Note 1: Coldset web offset printing is often (also) referred to as non-heatset web offset printing.  
1.2 This test method is also applicable to sheet-fed and coldset web offset printing ink vehicles.
Note 2: Vehicle is the liquid portion of the printing ink. Any substance that is dissolved in the liquid portion of the ink is a part of the vehicle.  
1.3 This test method is not applicable to ultra-violet (UV) or electron beam cured materials, which must be cured by exposure to UV light or an electron beam as part of the test for volatile content.  
1.4 This test method is based on Test Method D2369, in which the allowable ranges are ±0.1 g for specimen weight and ±5 °C for oven temperature. Interlaboratory studies have shown that specimen weight and oven temperature must both be more tightly controlled in order to improve the precision of test results for sheet-fed and coldset web-offset inks. Such inks typically contain a wide range of high-boiling hydrocarbons and often have a volatile content below 25 %.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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. For a specific hazard statement see 7.5.1  
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.
