Kahulugan at Layunin
5.1 Dry paint is often in contact with itself, especially in the area of doors and Windows, and can sometimes stick to itself (block) depending on its hardness, pressure, temperatura, humidity and length of time the surface has been in contact. This rigorous test method can be used to subjectively compare and evaluate the adhesion resistance of paints.

ASTM D 4946-89-2017 Adhesion Resistance of Architectural Coatings

Saklaw ng
1.1 This test method covers an accelerated procedure for assessing the face-to-face adhesion resistance of coatings for trade sales. This should not be confused with anti-adhesion test method D3003, which involves blocking of industrial coatings on metal substrates, nor with test method D2793, which specifically deals with wood product finishes and reports results on a satisfactory or unsatisfactory basis, rather than by the degree of blocking tendency as in this test method.

1.2 Values expressed in SI units of measurement shall be considered as standards. Ang mga halaga na ibinigay sa mga panaklong ay para sa sanggunian lamang.
