1.1本指南不同于通常的ASTM标准，因为它不涉及特定试验。相反，它是其他标准去角质测试方法新用户的入门指南（见术语） G15 对于去角质的定义）。 1.2本指南涵盖了在实验室加速环境和自然室外环境中对铝合金进行剥离试验的试样制备、暴露、检查和评估方面。目的是澄清现有测试方法中的任何差距。 1.3以国际单位制表示的数值应视为标准。括号中的英寸-磅单位仅供参考。 1.4本标准无意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 guide differs from the usual ASTM standard in that it does not address a specific test. Rather, it is an introductory guide for new users of other standard exfoliation test methods, (see Terminology G15 for definition of exfoliation). 1.2 This guide covers aspects of specimen preparation, exposure, inspection, and evaluation for conducting exfoliation tests on aluminum alloys in both laboratory accelerated environments and in natural, outdoor atmospheres. The intent is to clarify any gaps in existent test methods. 1.3 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only. 1.4 This standard does not purport to address all of the safety problems, 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.
