GB/T 18570.12-2008
AbolishedPreparation of steel substrates before application of paints and related products-Tests for the assessment of surface cleanliness - Part 12: Field method for the titrimetric determination of water-soluble ferrous ions
涂覆涂料前钢材表面处理 表面清洁度的评定试验 第12部分: 水溶性铁离子的现场滴定测定法
Application Summary AI generated
This standard specifies a field titration method for determining the concentration of water-soluble ferrous ions on steel surfaces. It is applied in industrial coating and painting operations, particularly for shipbuilding, offshore structures, and heavy machinery, to assess surface cleanliness before applying protective coatings. The test ensures that residual iron salts, which can cause premature coating failure, are within acceptable limits.
