1.1 本规程涵盖了评估已暴露于腐蚀性环境中进行测试的电镀测试板状况的首选方法。这是基于使用该方法的经验，该方法将标准10×15厘米（4×6英寸）的面板暴露在室外试验现场的标准ASTM机架上，在自然环境中。它还用于对经过加速试验的类似面板进行评级，如《规程》所述 第117页 方法 第287页 ，测试方法 第368页 ，和测试方法 B380型 。在本实践中，不考虑为使该方法适应实际生产零件的额定值所需的任何修改。 1.2 本规程仅适用于对基材起阴极作用的装饰性保护涂层，以钢或锌压铸件上的镍/铬或铜/镍/铬为代表。 它不适用于钢上的锌和镉等阳极牺牲涂层。 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。 1.4 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》中确立的国际公认标准化原则制定的。

1.1 This practice covers a preferred method for evaluating the condition of electroplated test panels that have been exposed to corrosive environments for test purposes. It is based on experience in use of the method with standard 10- by 15-cm (4- by 6-in.) panels exposed on standard ASTM racks at outdoor test sites in natural atmospheres. It has been used also for rating similar panels that have been subjected to accelerated tests such as those covered by Practice B117 , Method B287 , Test Method B368 , and Test Method B380 . Any modifications needed to adapt the method to rating actual production parts are not considered in this practice. 1.2 This practice refers only to decorative-protective coatings that are cathodic to the substrate, typified by nickel/chromium or copper/nickel/chromium on steel or zinc die castings. It is not intended for use with anodic sacrificial coatings such as zinc and cadmium on steel. 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.
