Designation: D 4541 – 02 Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers1 This standard is issued under the fixed designation D 4541; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval. 1.
