在极低浓度污染气体的人工大气中进行腐蚀试验

[中文适用范围]： 本文件规定了旨在确定体积分数小于或等于 10-6 的一种或多种流动污染气体对具有或不具有腐蚀保护的金属和合金测试样品和/或制品的影响的测试。 确定的温度和相对湿度条件。 本文件适用于 a) 金属及其合金，b) 金属涂层（阳极和阴极），c) 具有转化涂层的金属，d) 具有阳极氧化涂层的金属，以及 e) 具有有机涂层的金属。 [外文原描述]： This document specifies tests which are intended to determine the influence of one or more flowing polluting gas(es) at volume fractions less than or equal to 10 −6 on test samples and/or articles of metals and alloys with or without corrosion protection under determined conditions of temperature and relative humidity. This document is applicable to a) metals and their alloys, b) metallic coatings (anodic and cathodic), c) metals with conversion coatings, d) metals with anodic oxide coatings, and e) metals with organic coatings.
