1.1 本规程涵盖并规定了为规范目的对盐雾试验进行五次修改的条件。它们是按发展的时间顺序排列的: 1.1.1 附件A1 , 乙酸盐雾试验，连续。 1.1.2 附件A2 , 循环酸化盐雾试验。 1.1.3 附件A3 , 海水酸化试验，循环（SWAAT）。 1.1.4 附件A4 , 所以 2. 盐雾试验，循环。 1.1.5 附件A5 , 稀释电解质循环雾干试验。 1.2 本规程未规定用于特定产品的改性类型、试样或暴露期，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。国际单位制后括号中给出的值仅供参考，不被视为标准值。 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。 ====意义和用途====== 3.1 本规程适用于黑色金属和有色金属；还有有机和无机涂层。当与实践中描述的盐雾不同或更具腐蚀性的环境时，本文描述的变化是有用的 B117 是需要的。

1.1 This practice covers and sets forth conditions for five modifications in salt spray (fog) testing for specification purposes. These are in chronological order of their development: 1.1.1 Annex A1 , acetic acid-salt spray test, continuous. 1.1.2 Annex A2 , cyclic acidified salt spray test. 1.1.3 Annex A3 , seawater acidified test, cyclic (SWAAT). 1.1.4 Annex A4 , SO 2 salt spray test, cyclic. 1.1.5 Annex A5 , dilute electrolyte cyclic fog dry test. 1.2 This practice does not prescribe the type of modification, test specimen or exposure periods to be used for a specific product, 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 after SI units are provided for information only and are not considered 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. ====== Significance And Use ====== 3.1 This practice is applicable to ferrous and nonferrous metals; also organic and inorganic coatings. The variations described herein are useful when a different or more corrosive environment than the salt fog described in Practice B117 is desired.
