ASTM D7268-23

Standard Performance Specification for Seamless Knit Garments Including Intimates and Swimwear

ABSTRACT
This specification covers the evaluation of specific performance characteristics of importance in seamless knit garments, including camisoles, panties, slips, girdles and swimwear. Different tests shall be conducted in order to determine the following properties of seamless knit garments: bursting strength, colorfastness to laundering, colorfastness to drycleaning, colorfastness to crocking, colorfastness to light, colorfastness to perspiration, colorfastness to intimates, colorfastness to sea water, colorfastness to chlorinated pool water, colorfastness to chlorine and non-chlorine bleach, dimensional change, stretch, flammability, garnet twist, and fiber content.
SIGNIFICANCE AND USE
4.1 Upon mutual agreement between the purchaser and the supplier, seamless knit garments intended for this end use should meet all of the requirements listed in Table 1 of this specification. (A) See Note 4.  
4.2 It is recognized that, for purposes of fashion or aesthetics, the ultimate consumer of articles made from these fabrics may find acceptable products that do not conform to all of the requirements listed in Table 1. Therefore, one or more of the requirements in Table 1 may be modified by mutual agreement between the purchaser and the supplier.  
4.2.1 In such cases, any references to the specifications should specify that: “This product meets ASTM specifications XXXX except for the following characteristic(s).”  
4.3 Where no pre-purchase agreement has been reached between the purchaser and supplier, and in case of controversy, the requirements listed in Table 1 are intended to be used as a guide only. As noted in 4.2, ultimate consumer demands dictate varying performance parameters for a particular product.  
4.4 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 specification covers the evaluation of specific performance characteristics of importance in seamless knit garments, including camisoles, panties, slips, girdles and swimwear.  
1.2 The following safety hazards 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.  
1.3 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.
