Designation: D 3359 – 02Standard Test Methods forMeasuring Adhesion by Tape Test1This standard is issued under the fixed designationD 3359; the number immediatelyfollowing the designationindicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use byagencies of the Department of Defense.1. Scope1.1 These test methods cover procedures for assessing theadhesion of coating films to metallic substrates by applying andremoving pressure-sensitive tape over cuts made in the film.1.2 Test Method A is primarily intended for use at job siteswhile Test Method B is more suitable for use in the laboratory.Also, Test Method B is not considered suitable for films thickerthan 5 mils (125µm).NOTE 1—Subject to agreement between the purchaser and the seller,Test Method B can be used for thicker films if wider spaced cuts areemployed.1.3 These test methods are used to establish whether theadhesion of a coating to a substrate is at a generally adequatelevel. They do not distinguishbetween higher levels ofadhesion for which more sophisticated methods of measure-ment are required.NOTE 2—It should be recognized that differences in adherability of thecoating surface can affect the results obtained with coatings having thesame inherent adhesion.1.4 In multicoat systems adhesion failure may occur be-tween coats so that the adhesion of the coating system to thesubstrate is not determined.1.5 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonl...
