GB/T 18570.11-2009
AbolishedPreparation of steel substrates before application of paints and related products - Tests for the assessment of surface cleanliness - Part 11: Field method for the turbidimetric determination of water-soluble sulfate
涂覆涂料前钢材表面处理 表面清洁度的评定试验 第11部分：水溶性硫酸盐的现场浊度测定法
Application Summary AI generated
This standard specifies a field test method for measuring the concentration of water-soluble sulfate contaminants on steel surfaces before painting or coating. It is applied in industrial settings such as shipbuilding, bridge construction, and heavy machinery manufacturing, where surface cleanliness is critical for coating adhesion and corrosion prevention. The turbidimetric method allows on-site testing without laboratory equipment, ensuring that sulfate levels remain within acceptable limits for protective coating systems.
