GB/T 11374-1989 《Measuring method of nondestructive heat spray-on lining thickness》 Related products

The GB/T 11374-1989 standard specifies the nondestructive Measuring method of the thickness of the hot spray-on lining, referring to the international standards ISO 2064 and ISO 2063. This standard applies to the thickness measurement and evaluation of nonmagnetic coatings on various magnetic metal substrates and nonconductive coatings on nonmagnetic metal substrates. The standard includes the definition of terms, the selection of the Measuring method, the determination of the reference surface, and the Measuring method of the local thickness. According to the magnetic of the base material and the conductivity of the coating material, the magnetic method or the eddy current method can be selected for measurement. The report should include the average thickness of the coating, the minimum local thickness or the maximum local thickness, and determine the content of the report according to the specific application needs.
