1.1 本试验方法描述了使用扭转装置测量皮革的相对刚度。本试验方法不适用于湿蓝。 1.2 以SI单位表示的值应被视为标准。括号中显示的值仅供参考。 1.3 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。 1.4 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《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。======意义和用途====== 3.1 该测试方法旨在测量表观扭转模量 3 皮革标本。经验表明，皮革的扭转模量与在手套中感觉时称为刚度的特性直接相关。 4

1.1 This test method describes the use of a torsional apparatus for measuring the relative stiffness of leathers. This test method does not apply to wet blue. 1.2 The values stated in SI units are to be regarded as the standard. The values shown in parentheses are provided for information only. 1.3 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. 1.4 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 ====== 3.1 This test method is designed to measure the apparent torsional modulus 3 of a leather specimen. Experience has shown that the torsion modulus of leather is directly related to the characteristic known as stiffness when felt in a glove. 4
