1.1 本规程涵盖了使用腐蚀性浸渍进行周期性湿度暴露的程序。 2. 它规定了循环湿度测试所需的条件。 1.2 本规程未规定暴露样本的类型或暴露期，也未规定对结果的解释。 1.3 以国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 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咨询并建立适当的安全、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。 ====意义和用途====== 3.1 所述程序用于观察钢在延迟形成保护型锈的暴露条件下的行为。它还用于评估绝缘层上的密封层。 3.2 本规程不适用于在大气暴露条件下形成保护型锈蚀的钢的等级。

1.1 This practice covers procedures for conducting cyclic humidity exposures with a corrosive dip. 2 It sets forth the conditions required in cyclic humidity testing. 1.2 This practice does not prescribe the type of exposure specimen or exposure periods nor the interpretation to be given to the results. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 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 consult and 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. ====== Significance And Use ====== 3.1 The procedure described is used to observe the behavior of steels under exposure conditions that retard the formation of a protective type of rust. It is also used to evaluate seal coat on insulation. 3.2 This practice should not be used to rank steels that form a protective type of rust under atmospheric exposure conditions.
