标准摘要
[中文适用范围]： 本文件描述了用于腐蚀测试的涂层钢或试件的划线方法，其中涂层系统的干膜厚度小于 500 μm。 它仅作为指南，基于协作试验的结果，没有进行后续腐蚀测试来确定引入的划线标记是否适合此类测试。 本文件涵盖由以下材料制成的金属板或试件（经过化学处理或未经化学处理）的划线： ——钢； ——镀锌钢； ——铝合金； ——镁合金。 它不包括电镀金属或复合铝板的划线。 [外文原描述]： This document describes methods of scribing coated steel or test-pieces for corrosion tests, where the coating system is applied at dry film thicknesses of less than 500 μm. It is intended as a guideline only, being based on the results of a collaborative trial with no subsequent corrosion testing having been carried out to determine the suitability of the introduced scribe marks for such tests. This document covers the scribing of metallic panels or test pieces (chemically treated or not) made from: — steel; — galvanized steel; — aluminium alloys; — magnesium alloys. It does not cover the scribing of electroplated metal or clad aluminium panels.
