1.1 本试验方法涵盖液压和润滑液对双金属电偶的腐蚀性。 注1: 该试验方法复制了联邦标准791，方法5322.2。它使用了相同的仪器、测试条件和评估标准，但更明确地描述了测试程序。 1.2 以国际单位制表示的数值应视为标准。 1.2.1 例外情况-- 括号中给出的值仅供参考。 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》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 流体对双金属偶的腐蚀性是用于评估液压或润滑流体的特性之一。它是流体与黄铜-钢电偶在环境温度和50 %相对湿度。

1.1 This test method covers the corrosiveness of hydraulic and lubricating fluids to a bimetallic galvanic couple. Note 1: This test method replicates Fed-Std No. 791, Method 5322.2. It utilizes the same apparatus, test conditions, and evaluation criteria, but it describes test procedures more explicitly. 1.2 The values stated in SI units are to be regarded as standard. 1.2.1 Exception— The values given in parentheses are for information only. 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 ====== 5.1 Corrosiveness of a fluid to a bimetallic couple is one of the properties used to evaluate hydraulic or lubricating fluids. It is an indicator of the compatibility of a fluid with a brass on steel galvanic couple at ambient temperature and 50 % relative humidity.
