Arti dan Tujuan
3.1 Metode pengujian ini sangat cocok untuk pengukuran film bebas, and also suitable for the measurement of films on laboratory test plates.

3.2 The accuracy and accuracy of the thickness measurement may be affected by the deformation ability of the coating. This test method is not applicable to coatings that are prone to deformation under the load of the measuring instrument.

3.3 When the coating is applied to laboratory test plates, the accuracy and accuracy of the thickness measurement is also affected by the uniformity of the substrate.

Ruang lingkup
1.1 This test method includes the use of a micrometer to measure the dry film thickness of paint, varnisher, lacquer and related products. Programs A and B used fixed micrometers, and programs C and D used handheld micrometers. Procedures A and C are not recommended for films less than 12.5 m (0.5 mille) in thickness. The minimum thickness required for procedures B and D is a function of the minimum thickness required to be able to remove the sample as a free film.

1.2 The following procedures appear:

1.2.1 Prosedur A — Fixed micrometer for measuring flat rigid surface coatings.

1.2.2 Prosedur B — Fixed micrometer for measuring free film.

1.2.3 Program C — Handheld micrometer for measuring coatings on flat rigid surfaces.

1.2.4 Program D — Handheld micrometer for measuring free films.

1.3 Nilai yang dinyatakan dalam satuan SI akan berlaku. Nilai yang diberikan dalam tanda kurung hanya untuk referensi.
