Designation: D 3359 - 02 INTERNATIONAL Standard Test Methods for Measuring Adhesion by Tape Test1 This standard is issued under the fixed designation D 3359; the number immediately following the designation indicates the year of superscript epsilon (e) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. 1.
