The GB/T 4956-2003 standard specifies a magnetic method for measuring the thickness of nonmagnetic coatings on magnetic substrates. This method is suitable for the measurement of the thickness of nonmagnetic films or coatings coated on the surface of magnetic materials, such as paint films, Coatings or Miscellaneous nonmagnetic coatings. By utilizing the principle of magnetic induction, this standard provides a method for accurate measurement of Coatings thickness to ensure product mass and conformity, suitable for a variety of industrial application scenarios that require precise control of the thickness of coatings.
