标准摘要
[中文适用范围]: 本部分ISO 4628规定了一种评估涂层板或其他涂层测试样品上因腐蚀环境引起的划痕或其他人工缺陷周围的脱层和腐蚀的方法。 本部分ISO 4628不包括点蚀或坑深的评估。 注1:腐蚀环境的例子包括人工环境,如盐雾试验方法中使用的ISO 9227,以及海水浸泡试验方法中使用的ISO 15711。自然环境也可以使用。 注2:其他缺陷的程度也可以在评估脱层和腐蚀的同时确定。方法如下: - 根据ISO 4628-2评估起泡; - 根据ISO 4628-3评估锈蚀; - 根据ISO 4628-4评估开裂; - 根据ISO 4628-5评估剥落; - 根据ISO 4628-10评估均匀腐蚀。 [外文原描述]: ISO 4628-8:2012 specifies a method for assessing delamination and corrosion around a scribe or other artificial defect on a coated panel or other coated test specimen, caused by a corrosive environment. ISO 4628-8:2012 does not cover evaluation of pitting corrosion or pit depth.
