The GB/T 4956-1985 standard specifies the method of nondestructive measurement of the thickness of nonmagnetic coatings (such as enamels and enamels) on magnetic metal substrates using magnetic thickness gauges. The standard is suitable for measurement on flat samples. The thickness of nonmagnetic coatings is accurately evaluated by magnetic methods to ensure the uniformity and mass of coatings.
