GB/T 13288-1991 《Assessment of steel surface roughness grades before painting (comparative sample method) (neq ISO 8503:1985)》 Related products

This standard specifies the procedure and method for assessing the surface roughness of steel before painting by comparing the sample method, which is applicable to the surface of steel cleaned by abrasive injection or ejection. The standard is developed with reference to ISO 8503:1985 and divides the asperity of the steel surface into several grades, and provides detailed assessment procedures and requirements. This standard is suitable for the assessment of steel surface roughness requirements before protective treatment and is an important basis for ensuring coating adhesion and anti-corrosion performance.
