This practice utilizes symbols to depict security systems and equipment requirements for architectural or engineering drawings that are produced either manually or by computer aided design (CAD). The symbols depicted include some symbols that have already been somewhat universally accepted or that have already been adopted by a standards-writing body. Generic symbols of a class of security device may be sufficient in some instances. Moreover, the need to provide a measure of security in the actual drawing may also suggest a need to utilize a generic symbol rather than to depict the exact device being installed. In the event that a greater level of detail is required, it is possible to combine many of the symbols to create new symbols that achieve the desired level. While some combinations of symbols are shown, it would be impractical to attempt to depict every conceivable combination of symbols.1.1 This practice utilizes symbols to depict security systems and equipment requirements for architectural or engineering drawings that are produced either manually or by computer aided design (CAD). The symbols depicted include some symbols that have already been somewhat universally accepted or that have already been adopted by a standards-writing body, such as by the National Fire Protection Association.1.2 It is not proposed that all of the symbols need to be utilized since the level of detail required for drawings is likely to vary. Generic symbols of a class of security device may be sufficient in some instances. Moreover, the need to provide a measure of security in the actual drawing may also suggest a need to utilize a generic symbol rather than to depict the exact device being installed.1.3 In the event that a greater level of detail is required, it is possible to combine many of the symbols to create new symbols that achieve the desired level. While some combinations of symbols are shown, it would be impractical to attempt to depict every conceivable combination of symbols. It is also the intent of this practice that the symbols be capable of being continuously expanded and modified as the industry state of the art changes or as emphasis varies. For example, little attention is given to document security in the security symbols since such requirements are not generally fully met during construction periods but are rather developed and provided for subsequently. Since much of this equipment is not installed but is “placed,” such as furniture, there is only one symbol proposed (for example, for document shredders).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.

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 SymbolsNOTE 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.FIG. 2 Guide to Order of ASTM Care Symbols4.6 The care label symbol system is based on five basic care symbols representing five operations: washing, bleaching, drying, ironing, and professional textile care.4.7 One color is used for all care symbols in this care labeling system.NOTE 1: While this symbol system uses one color, it is harmonious with tri-color systems such as the Canadian system because the instructions are clear whether printed in one or three colors.4.8 This guide does not specify the type of label material or fabric to use. However, appropriateness for consumer comfort is recommended.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.
