GB/T 11374-2012 《Thermal spraying coating - Nondestructive methods for measurement of thickness》 Related products

The GB/T 11374-2012 standard specifies nondestructive measuring methods for thermal spray-on lining thickness. This standard applies to all thermal spray methods, such as flame spraying, arc lame plating, plasma lame plating, etc., for the measurement of the thickness of nonmagnetic coatings on magnetic metal substrates and nonconductive coatings on nonmagnetic metal substrates. The standard describes in detail terms and definitions, selection of measuring methods, determination of reference surfaces, and local thickness Measuring methods. Depending on the properties of the base material, the magnetic method or eddy current method can be selected for measurement. The standard also specifies the size and location distribution of the reference surface, as well as the content of the Coating thickness report for different purposes, such as average thickness, minimum local thickness, or maximum local thickness.
