GB/T 8923.4-2013
ActivePreparation of steel substrates before application of paints and related products - Visual assessment of surface cleanliness - Part 4: Initial surface conditions 、preparation grades and flash rust grades in connection with high-pressure water jetting
涂覆涂料前钢材表面处理 表面清洁度的目视评定 第4部分：与高压水喷射处理有关的初始表面状态、处理等级和闪锈等级
Application Summary AI generated
This standard specifies visual assessment criteria for initial surface conditions, preparation grades, and flash rust grades on steel substrates treated by high-pressure water jetting. It is applied in industrial coating and corrosion protection contexts, such as shipbuilding, offshore structures, and heavy machinery manufacturing, where water jetting is used as an alternative to dry abrasive blasting. The standard ensures consistent quality control by providing reference descriptions and photographic examples for evaluating surface cleanliness before applying paints or protective coatings.
