本文件规定了用于评价使用于户外盐污染环境中的金属材料耐蚀性的加速腐蚀试验的仪器和试验方法,不论被测试材料是否具有永久性或暂时性腐蚀防护。本文件规定了试样循环暴露于中性盐雾、“干”和“湿”试验环境的试验方法。本文件对试样的类型和暴露时间不作明确规定。
本试验与传统常规的加速腐蚀试验,如中性盐雾试验(NSS)相比,其最大的优点在于它能更好地再现发生在户外盐污染环境下的腐蚀。
本文件的加速腐蚀试验适用于:
——金属及其合金;
——金属覆盖层(阳极性的和阴极性的);
——转化覆盖层;
——阳极氧化物覆盖层;
——金属材料上的有机覆盖层。
注:GB/T31588.1中给出了覆盖层的测试方法,以确定覆盖层在划痕贯穿基材的情况下对各种循环腐蚀条件(包括潮湿期间试样上的水凝结)的耐受性。
