1.1 本规程涵盖了用于评估可机洗T恤衫重要特性的试验方法和程序。T恤可以由任何纺织纤维或纤维混合物组成的针织织物制成，并用作内衣或外衣。 1.2 T恤衫的特性可以作为最终产品或在任何中间加工阶段进行评估。 1.3 本规程不包括用于洗手或干洗护理的T恤衫。 1.4 以国际单位制或英寸磅单位表示的数值应单独视为标准值。每个系统中所述的值不一定完全相等；因此，为了确保符合标准，每个系统应独立使用，两个系统的值不得合并。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 本规程可用于评估可洗T恤衫的相关特性。 4.2 T恤衫可能会经过额外的工序，如服装染色、衣物洗涤、印花、刺绣或镶边。单个过程或组合过程可能影响最终产品的性能。 4.3 采购商和供应商之间可通过相互协议使用该做法来制定采购规范。

1.1 This practice covers test methods and procedures used to evaluate important characteristics of machine washable T-shirts. T-shirts may be made of knitted fabric composed of any textile fiber(s) or blend of fibers and intended to be used as underwear or as an outer garment. 1.2 T-shirts' characteristics may be assessed either as a final product or at any intermediate processing stage. 1.3 This practice excludes T-shirts intended for hand washing or dry cleaning care. 1.4 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 necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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. ====== Significance And Use ====== 4.1 This practice may be used to evaluate pertinent characteristics of washable T-shirts. 4.2 T-shirts may be subject to extra processes such as garment dyeing, garment washing, printing, application of embroidery or trims. An individual process or combination or processes may affect the performance of the final product. 4.3 This practice may be used by mutual agreement between the purchaser and the supplier to establish purchasing specifications.
