ASTM D1400 – Standard Test Method for Nondestructive Measurement of Dry Film Thickness of Nonconductive Coatings Applied to a Nonferrous Metal Base (Withdrawn 2006)
Description:
Scope
1.1 This test method covers the nondestructive measurement of the dry film thickness of electrically nonconductive coatings applied over a nonferrous metal base using commercially available eddy current instruments. This test method is intended to supplement manufacturers’ instructions for the manual operation of the gages, and is not intended to replace them.
1.2 This test method is not applicable to coatings that will be readily deformable under the load of the measuring instruments, as the instrument probe must be placed directly on the coating surface to take a reading.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
