ASTM D5489-18(2023)(Guide)
Standard Guide for Care Symbols for Care Instructions on Textile Products

SIGNIFICANCE AND USE
4.1 This guide provides symbols and a system for their use by which care instructions for textile products can be conveyed in a simple, space-saving, and easily understood pictorial format that is not language dependent. See also ADJD5489-E-PDF. Currently, the FTC Care Labeling Rule recognizes Guide D5489-96c.  
4.2 Care symbols are an important means for identifying the appropriate care procedure for home laundering, commercial laundering, professional textile care, and coin-operated drycleaning, of textile products.  
4.3 Care labeling using symbols can be used by the purchaser to select textiles on the basis of the care method required without knowledge of the language. The FTC Care Labeling Rule specifies Guide D5489-96c symbols. Additional changes in words and symbols have been added to this guide which are not covered by 16 CFR 423. In the United States, when care symbols only are to be included in a care label, the FTC requires that the Guide D5489-96c version of symbols must be used. However, the symbols, as included in this standard version (Guide D5489-18), may be used if symbols are used in addition to full care instructions written in English wording.  
4.4 In countries in which a word-based care labeling system is required, the care symbol system may be used as a supplemental system.  
4.5 The word-based instructions for each symbol in this guide are harmonious with Terminology D123, and Terminology D3136, the United States Federal Trade Commission Care Labeling Rule, 16 CFR 423, and industry practice (see Figs. 1 and 2).
FIG. 1 Commercial and Home Laundering and Professional Textile Care Symbols
Note 1: This figure illustrates the symbols to use for laundering and drycleaning instructions. As a minimum, laundering instructions shall include, in order, four symbols: washing, bleaching, drying, and ironing; and, professional textile care instructions shall include one symbol. Additional symbols or words may be used to clarify the instructions.  
...
SCOPE
1.1 This guide provides a uniform system of symbols for the disclosure of care instructions on textile products such as apparel, piece goods, and household and institutional articles, hereinafter referred to as “textile,” or “textile product.”  
1.2 This guide provides a comprehensive system of symbols to represent care instructions reducing language-dependent care instructions.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

The fabrics shall meet the following performance requirements: breaking strength which shall be determined using a constant rate of extension tensile testing machine; resistance to yarn slippage; tearing strength; dimensional change during pressing and finishing, after laundering, or after dry cleaning; colorfastness to laundering and dry cleaning; shade change due to sodium hypochlorite bleaching or non-chlorine bleaching, burnt gas fumes, dry and wet crocking, perspiration, and xenon-arc light; fabric smoothness after pressing, laundering, and dry cleaning; and flammability.
SIGNIFICANCE AND USE
4.1 Fabrics intended for this end-use should meet all of the requirements listed in Table 1.  (A) There is more than one method that can be used to measure breaking strength, tearing strength and colorfastness. These methods cannot be used interchangeably since there may be no overall correlation between them (see Note 2 and Note 3).(B) See Note 5.  
4.2 It should be recognized that fabrics can be produced utilizing an almost infinite number of combinations of construction variables (e.g., type of fibers, percentage of fibers, yarn twist, yarn number, warp and pick count, chemical and mechanical finishes). Additionally, fashion or aesthetics dictate that the ultimate consumer may find acceptable articles made from fabrics that do not conform to all of the requirements in Table 1.  
4.2.1 Hence, no single performance specification can possibly apply to all the various fabrics that could be utilized for this end-use.  
4.3 The uses and significance of particular properties and test methods are discussed in the appropriate sections of the specified test methods.
SCOPE
1.1 This performance specification covers fabrics for woven blouses, dresses, dress shirts, and sport shirts.  
1.2 This performance specification is not applicable to woven fabrics used for interlinings.  
1.3 These requirements apply to the length and width directions for those properties where fabric direction is pertinent.  
1.4 When a fabric requires special treatment, specific methods will be described as they are developed for that material, and such special tests will have precedence over these general requirements.  
1.5 The following precautionary caveat pertains only to the test methods described in this performance specification. 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.
