GB/T 13288.2-2011 《Preparation of steel substrates before application of paints and related products - Surface roughness characteristics of blast-cleaned substrates - Part 2: Method for the grading of surface profile of abrasive blast-cleaned steel - Comparator procedure》 Related products

This standard specifies a method for determining the surface roughness grade of steel after jet cleaning, and assesses the surface roughness by comparing the sample method. The standard provides a reference sample for comparison and a measurement process to ensure that the asperity of the steel surface after jet cleaning meets the requirements of the coating. This method can help to accurately evaluate the treatment effect of the steel surface and ensure the adhesion and final performance of the coating.
