AbolishedPreparation of steel substrates before application of paints and related products-Tests for the assessment of surface cleanliness-Part 8:Field method for the refractometric determination of moisture
涂覆涂料前钢材表面处理 表面清洁度的评定试验 第8部分：湿气的现场折射测定法
Application Summary AI generated
This standard specifies a field method for determining the moisture content on steel surfaces using refractometry, applied before the application of paints or protective coatings. It is used in industrial sectors such as shipbuilding, construction, and heavy machinery manufacturing to assess surface cleanliness and ensure coating adhesion. The test is conducted on-site to verify that steel substrates are sufficiently dry, preventing coating failures like blistering or corrosion.
