The ASTM D 1186-2001 standard describes the use of non-Destructiveness methods for the measurement of dry-film thickness of nonmagnetic coatings applied to non-ferrous substrates. The standard covers two test methods: Method A uses a magnetic pull-off meter and Method B uses a Magnetic flux meter. These methods are suitable for nondestructive measurement of nonmagnetic coatings on non-ferrous metal substrates, but not for coatings that are prone to deformation under measuring instrument load. The standard emphasizes that the use of SI units as the standard requires users to confirm their own safety and health practices.
