1.1 这些测试方法涵盖了测量织物长度的四种选项，适用于材料的整卷或螺栓。 1.2 有以下四种经批准的测量长度选项: 1.2.1 选项A- 手（部分 6 ). 1.2.2 选项B- 鼓（部分 7 ). 1.2.3 选项C- 时钟（部分 8 ). 1.2.4 选项D- 折叠（部分 9 ). 1.3 以SI单位或美国习惯单位表示的值应单独视为标准值。每个系统中陈述的值可能不完全等同；因此，每个系统必须独立于另一个系统使用，不能以任何方式组合值。 1.4 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。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法规限制的适用性。1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 These test methods cover four options for measuring fabric length and are applicable to full rolls or bolts of materials. 1.2 There are four approved options of measuring length as follows: 1.2.1 Option A— Hand (Section 6 ). 1.2.2 Option B— Drum (Section 7 ). 1.2.3 Option C— Clock (Section 8 ). 1.2.4 Option D— Folding (Section 9 ). 1.3 The values stated in either SI units or in U.S. customary units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way. 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.
