1.1 This test method covers the measurement of film thickness of dried films of paint, varnish, lacquer, and related products using micrometers. Procedures A and B utilize stationary micrometers and Procedures C and D, hand-held micrometers. Procedures A and C are not recommended for films less than 12.5 μm (0.5 mils) in thickness. The minimum thickness required for Procedures B and D is a function of that required to enable removal of the sample as a free film.
1.2 The procedures appear as follows:
1.2.1 Procedure A-Stationary micrometer for measuring coatings applied to plane rigid surfaces.
1.2.2 Procedure B-Stationary micrometer for measuring free films.
1.2.3 Procedure C-Hand-held micrometer for measuring coatings applied to plane rigid surfaces.
1.2.4 Procedure D-Hand-held micrometer for measuring free films.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
