Active Standard: Standard Test Method for Evaluating Adhesion by Knife

ASTM D6677

Scope

1.1 This test method covers the procedure for assessing the adhesion of coating films to substrate by using a knife.

1.2 This test method is used to establish whether the adhesion of a coating to a substrate or to another coating (in multi-coat systems) is at a generally adequate level.

Note 1: The term “substrate” relates to the basic surface on which a coating adheres (may be steel, concrete, etc. or other coating).

1.3 This method can be used in the laboratory and field.
