1.1 本指南涵盖了进行加速试验的测试程序，以评估应用于机械紧固件的各种涂层的相对耐腐蚀性。这种方法可以评估一般腐蚀和缝隙腐蚀等腐蚀机制。可选择试验持续时间以达到任何所需的腐蚀暴露水平，并为确定相对涂层耐腐蚀性提供参考框架。将紧固件拧紧至所需张力并进行本试验程序的紧固件可进行评估，以模拟各种使用条件。如果没有大量累积的现场结果，很难将测试持续时间或测试周期数与给定应用的实际使用寿命联系起来。 1.2 本标准不包括从动紧固件的测试，如钉子、订书钉、螺钉和拉力螺栓。 1.3 单位- 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。 1.4 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。 1.5 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。

1.1 This guide covers test procedures for performing accelerated tests to evaluate relative corrosion resistance of various coatings applied to mechanical fasteners. Corrosion mechanisms such as general and crevice corrosion may be evaluated with this method. Test duration may be selected to achieve any desired level of corrosion exposure and provides a frame of reference to determine relative coating resistance to corrosion. Fasteners tightened to a desired tension and subjected to this test procedure may be evaluated to simulate a variety of service conditions. Without large amounts of accumulated field results, it is difficult to relate test duration or the number of test cycles to actual service life for a given application. 1.2 This standard is not intended to cover tests of driven fasteners such as nails, staples, screws and lag bolts. 1.3 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. 1.5 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.
