GB/T 13288.4-2013 《Preparation of steel substrates before application of paints and related products - Surface roughness characteristics of blast-cleaned substrates - Part 4: Method for the calibration of ISO surface profile comparator and for the determination of surface profi - Stylus instrument procedure》 Related products

The GB/T 13288.4-2013 standard specifies the calibrating and Measuring method for measuring the surface roughness of steel after jet cleaning using the stylus method. The standard details the calibrating requirements for ISO surface roughness comparison samples and the application of the stylus method in assessing the surface roughness of steel, including measurement equipment, operation steps and data processing methods. The standard aims to ensure the conformity and accuracy of the surface roughness measurement, providing scientific basis and technical support for steel surface preparation before coating. It is suitable for steel surface quality control in industrial production, especially in related fields involving anti-corrosion coating adhesion and coating effect.
