1.1 本试验方法涵盖皮革试样表面积的测量。除非另有规定，否则待测量表面应为晶粒表面或最接近晶粒表面的表面。本试验方法不适用于蓝湿革。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 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、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《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本试验方法旨在测量试样在进行可能影响表面积的各种试验之前和之后的面积。可以使用此类测量的两个测试程序是皮革的表观密度和皮革对合成汗液的阻力。

1.1 This test method covers the measurement of the surface area of leather test specimens. Unless otherwise specified, the surface to be measured shall be the grain surface or the surface most closely adjacent to the grain surface. This test method does not apply to wet blue. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 designed to measure the area of specimens before and after they are subjected to various tests that may effect surface area. Two test procedures wherein such measurements could be used are for the apparent density of leather and the resistance of leather to synthetic perspiration solution.
