GB/T 18570.2-2009
ActivePreparation of steel substrates before application of paints and related products - Tests for the assessment of surface cleanliness - Part 2: Laboratory determination of chloride on cleaned surfaces
涂覆涂料前钢材表面处理 表面清洁度的评定试验 第2部分：清理过的表面上氯化物的实验室测定
Application Summary AI generated
This standard specifies a laboratory test method for determining the concentration of chloride salts on steel surfaces that have been cleaned in preparation for painting or coating. It is applied in industrial coating and corrosion protection contexts, particularly for steel structures such as bridges, ships, and storage tanks, where residual chlorides can cause premature coating failure. The test is used by quality control and inspection personnel to verify surface cleanliness before applying protective paint systems.
