significance And Use:

scope:

1.1 This test method covers the measurement of dry film thickness of coatings applied to a smooth, textured or curved rigid substrate of wood or a wood-based product

1.2 This test method covers the preparation of wood or wood-based specimens for the purpose of microscopical measurement of dry film thickness.

1.3 This test method suggests an interpretation of dry film thickness of coatings on wood or wood-based products when porous substrates are coated.

1.4 This test method suggests an interpretation of dry film thickness of coatings on wood or wood-based products when substrate attached or non-attached fibers occur in the dry film.

1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
