|These test methods cover procedures for assessing the adhesion
of coating films to metallic substrates by applying and removing
pressure-sensitive tape over cuts made in the film.
NOTE 1—This test method has been reported being used to measure
adhesion of organic coatings on soft substrates (for example, wood
and plastic). Issues with plastic substrates are noted in Appendix
X1. A similar test method, ISO 2409, permits tests on soft
substrates (for example, wood and plaster). Precision and bias data
on the later is lacking. Test Methods D3359 was developed with
metal as the substrate and, in the absence of supporting precision
and bias data, is so limited.
Test Method A is primarily intended for use at job sites while
Test Method B is more suitable for use in the laboratory. Also,
Test Method B is not considered suitable for films thicker than 5
NOTE 2—Subject to agreement between the purchaser and the
seller, Test Method B can be used for thicker films if wider spaced
cuts are employed.
These test methods are used to establish whether the adhesion of
a coating to a substrate is at a generally adequate level. They do
not distinguish between higher levels of adhesion for which more
sophisticated methods of measurement are required.
NOTE 3—It should be recognized that differences in adherability
of the coating surface can affect the results obtained with
coatings having the same inherent adhesion.
This test method is similar in content (but not technically
equivalent) to ISO 2409.
In multicoat systems adhesion failure may occur between coats so
that the adhesion of the coating system to the substrate is not
