ISO 16071:2015规定了加速大气腐蚀试验中使用的试验方法、试剂和程序,该试验包括每周两次在1%NaCl的轻度酸化溶液中暴露6小时,然后在35°C的恒定温度下,在95%相对湿度和50%相对湿度之间进行受控湿度循环。
它没有规定试样的尺寸、特定产品的暴露时间或结果的解释。相关产品规范中提供了此类详细信息。
加速实验室腐蚀试验适用于金属及其合金、金属涂层(阳极或阴极)、化学转化涂层和金属材料上的有机涂层。
ISO 16071:2015 specifies the test method, the reagents, and the procedure to be used in an accelerated atmospheric corrosion test constituting a 6 h exposure to a slightly acidified solution of 1 % NaCl twice weekly, followed by a condition of controlled humidity cycling between 95 % RH and 50 % RH at a constant temperature of 35 °C.
It does not specify the dimensions of the tests specimens, the exposure period to be used for a particular product, or the interpretation of the results. Such details are provided in the appropriate product specifications.
The accelerated laboratory corrosion test applies to metals and their alloys, metallic coatings (anodic or cathodic), chemical conversion coatings, and organic coatings on metallic materials.
