ASTM D 3359 : 2017 : REDLINE

1.1These test methods cover procedures for assessing the adhesion of relatively ductile coating films to metallic substrates by applying and removing pressure-sensitive tape over cuts made in the film.

1.2Test Method A is primarily intended for use in the field while Test Method B is more suitable for use in laboratory or shop environments. Also, Test Method B is not considered suitable for films thicker than 125μm (5 mils) unless wider spaced cuts are employed and there is an explicit agreement between the purchaser and seller.

1.3These test methods are used to evaluate whether the adhesion of a coating to a substrate is adequate for the user’s application. They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required.

1.4This test method is similar in content (but not technically equivalent) to ISO 2409.

1.5In multicoat systems adhesion failure may occur between coats so that the adhesion of the coating system to the substrate is not determined.

1.6The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.7This standard does not purport to address 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.
