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.

ASTM D4151-23(Test Method)
Standard Test Method for Flammability of Blankets

SIGNIFICANCE AND USE
5.1 This test method for the determination of the flammability of blankets is considered satisfactory for acceptance testing of commercial shipments of blankets since this test method has been used extensively in the trade for acceptance testing.  
5.2 This test method is intended to evaluate fabrics used in electric blankets without the resistance heating wires.  
5.3 Fabrics are potentially combustible. Some fabrics when used for blankets are potentially dangerous to the user depending on the ease of ignition, rapidity, and intensity of burning. This test method addresses some of these characteristics.
SCOPE
1.1 This test method provides a means to identify blanket fabrics which ignite easily and propagate flame across the surface.  
1.2 This test method specifies the procedures described in the “Voluntary Blanket Flammability Standard” which has been used by the blanket industry in the United States since 1972.  
1.3 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.
Note 1: This test method is not identical to 16 CFR Part 1610, Flammability of Clothing Textiles. Consumer Product Safety Commission regulations require that fabrics introduced into commerce meet the requirements of 16 CFR Part 1610.  
1.4 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
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.

ASTM D6545-22(Test Method)
Standard Test Method for Flammability of Textiles Used in Children's Sleepwear

SIGNIFICANCE AND USE
5.1 This test method is suitable for evaluating flammability characteristics and laundering durability of textiles used in the manufacture of children's sleepwear. It is not suitable for evaluating the flammability characteristics of textiles for other product applications or ignition scenarios.  
5.2 The procedure for flammability testing used in this test method is technically equivalent to those used in 16 CFR 1615 and 1616. This test method does not include detailed specimen sampling plans, or the regulatory and record keeping requirements cited in the federal regulations. Please consult 16 CFR 1615 and 1616 for information for these operations.  
5.3 This test method is suitable for training technicians to conduct the federal test and can serve as a laboratory reference.  
5.4 Test Method D6545 is very different from 16 CFR 1610 and from Test Method D1230.
SCOPE
1.1 This test method evaluates the relative flammability of textiles and garments intended for use in children's sleepwear. The procedures of this test method follow testing and laundering procedures used to evaluate the flammability of children's sleepwear contained in U.S. Federal Regulations 16 CFR 1615 and 1616.  
1.2 A textile used in children's sleepwear must be tested in its original state and after 50 laundering and drying cycles to assess the flame resistance of the textile relative to its use life.  
1.3 This method is identical to the method outlined in the regulations 16 CFR 1615 or 1616. The regulation includes additional information such as sampling plans, record keeping requirements, and interpretations for compliance applicable to children’s sleepwear. Please consult 16 CFR 1615 and 1616 for these operations and interpretations.  
1.4 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.  
1.5 This test method 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.  
1.6 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
1.7 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 health practices and determines the applicability of regulatory limitations prior to use. Specific precautionary information is found in 8.5 and 9.5.  
1.8 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 Performance Specification for Soft Window Covering Fabrics for Household Use

ABSTRACT
This performance specification establishes the evaluation of specific performance characteristics of any washable or dry-cleanable soft window covering fabrics, whether lined or unlined, for household use. The characteristics to be evaluated prior to repeated refurbishing include, but are not limited to, seam strength and appearance, uniformity of shade (part to part), and size consistency (side to side and part to part). Consequently, the characteristics to be evaluated after repeated refurbishing include, but are not limited to, colorfastness, dimensional change, seam strength, appearance, and compatibility of components. Compatibility of dimensional change between drapery fabric and lining should be noted.
SIGNIFICANCE AND USE
4.1 This specification may be used to evaluate pertinent performance characteristics of washable and drycleanable soft window coverings, whether lined or unlined.  
4.1.1 Soft window covering characteristics to be evaluated prior to repeated refurbishing include, but are not limited to, seam strength and appearance, uniformity of shade (part to part), and size consistency (side to side and part to part).  
4.1.2 Soft window covering characteristics to be evaluated after repeated refurbishing include, but are not limited to, colorfastness, dimensional change, seam strength, appearance, and compatibility of components. Compatibility of dimensional change between drapery fabric and lining should be noted.  
4.2 The specified home laundry machine settings do not reflect advances in cycle design or special features of washer and dryers which enhance the performance of these products. The standard washing and drying procedure reflects the minimum capabilities of current home laundering equipment used by consumers in accordance with care label instructions.  
4.2.1 The reproducibility of the results of the test method specified in 9.2 depends on the use of procedures for automatic home laundering as specified on care labels.  
4.3 The areas to be evaluated and the criteria assigned to these areas shall be set by mutual agreement between purchaser and supplier.
SCOPE
1.1 This specification covers the evaluation of specific performance characteristics of any washable or drycleanable soft window covering.  
1.2 This specification is not a specification for washable or drycleanable soft window coverings but may be used by mutual agreement between the purchaser and the supplier to establish material specifications.
