1.1 本规程涵盖了记录金属涂层钢试样大气腐蚀试验数据的程序。其目的是确保( 1. )测试前对材料进行完整识别( 2. )目视检查期间材料外观的客观报告，以及( 3. )在退化的特定阶段和测试结束时，进行充分的摄影、缩微摄影和化学实验室检查。 1.2 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。 1.3 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 使用这种做法将最大限度地提高金属涂层钢大气试验的效益。它还将有助于比较从一个位置到另一个进行了类似测试的位置的结果。

1.1 This practice covers a procedure for recording data of atmospheric corrosion tests of metallic-coated steel specimens. Its objective is the assurance of ( 1 ) complete identification of materials before testing, ( 2 ) objective reporting of material appearance during visual inspections, and ( 3 ) adequate photographic, micrographic, and chemical laboratory examinations at specific stages of deterioration, and at the end of the tests. 1.2 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. 1.3 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 Use of this practice will maximize the benefits to be gained from atmospheric testing of metallic-coated steel. It will also aid in comparing results from one location to another where similar tests have been conducted.
