ActiveConversion coatings on metallic materials--Determination of coating mass per unit area--Gravimetric methods
金属材料上的转化膜 单位面积膜质量的测定 重量法
Application Summary AI generated
This standard specifies gravimetric methods for determining the mass per unit area of conversion coatings (such as phosphate, chromate, or oxide layers) on metallic materials. It is applied in manufacturing and quality control settings to verify coating thickness and uniformity on metal parts, particularly in automotive, aerospace, and general metal finishing industries. The standard ensures compliance with coating specifications by providing a precise weight-based measurement technique.
