Historical Standard: ASTM D6677-07 Standard Test Method for Evaluating Adhesion by Knife
SUPERSEDED (see Active link, below)
ASTM D6677
1. 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 1The 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.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address all of 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.
