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。本试验方法不适用于蓝湿革。 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是精确的等效值，因此，每个系统应独立于另一个系统使用。将两个系统的值合并可能会导致不符合标准。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

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 and health practices and determine the applicability of regulatory limitations prior to use.
