1.1 本试验方法包括通过测量水蒸气通过试样的速率来测定皮革对水蒸气的渗透性。该测试方法不适用于湿蓝色。 1.2 以英寸磅或国际单位制表示的数值应单独视为标准值。每个系统中规定的值可能不完全相等，因此，每个系统应独立使用。将两个系统的值合并可能导致不符合标准。 1.3 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。 1.4 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《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 本试验方法适用于所有类型的皮革。 4.2 水蒸气渗透性是鞋、手和衣服相对舒适度的几个因素之一。

1.1 This test method covers the determination of the permeability of leather to water vapor by measuring the rate at which water vapor passes through a test specimen. This test method does not apply to wet blue. 1.2 The values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system may not be exact equivalents, therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 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 ====== 4.1 This test method is intended for use on all types of leathers. 4.2 Water vapor permeability is one of several factors contributing to the relative comfort of footwear, handwear, and garments.
