AbolishedPreparation of steel substrates before application of paints and related products-Tests for the assessment of surface cleanliness-Part 9:Field method for the conductometric determination of water-soluble salts
涂覆涂料前钢材表面处理 表面清洁度的评定试验 第9部分：水溶性盐的现场电导率测定法
Application Summary AI generated
This standard specifies a field method for measuring the concentration of water-soluble salts on steel surfaces using electrical conductivity. It is applied in industrial coating and painting operations, particularly for shipbuilding, bridges, and structural steel, to assess surface cleanliness before applying protective coatings. The test ensures that salt contamination levels are within acceptable limits to prevent coating failure and corrosion.
