Scope of
1.1 These test methods include non-destructive measurement of dry film thickness of non-magnetic coatings applied to ferrous metal substrates using commercially available test instruments. The test method covers only the use of instruments based on magnetic measurement principles. Test method A provides the measurement of the film using a magnetic pull meter and test method B provides the measurement of the film using a fluxmeter.

1.2 These test methods are not applicable to coatings that are prone to deform under the load of the measuring instrument, as the instrument probe needs to be placed directly on the surface of the coating to take a reading.

1.3 Values given in SI units of measurement shall be regarded as standards. Values in parentheses are for reference only.

1.4 This standard is not intended to address all safety issues, if any, associated with its use. It is the responsibility of users of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
