Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers

Importancia y uso:

4.1 The pull-off strength of a coating is a performance property that may be referenced in specifications. This test method serves as a means for uniformly preparing and testing coated surfaces, and evaluating and reporting the results. This test method is applicable to any portable apparatus meeting the requirements for determining the pull-off strength of a coating in this standard (see Annex A1 – Annex A5).

4.2 Variations in results with the same coating are likely when any parameter of the test is changed. This includes change in glue, load fixture size, substrate coating cure time, pull rate, environmental conditions, if the coating is scored, or using a different device. Therefore, when a series of results will be compared with one another or used for statistical analysis, the type of apparatus, substrate, test procedures, glue type, and if scoring is used should be the same for the pulls considered.4 It is recommended that these parameters and the environmental conditions allowed during the test be mutually agreed upon between the interested parties.

4.3 The purchaser or specifier shall designate a specific test method procedure; B, C, D, E, or F and test Protocol; 1, or 2, when calling out this standard. In cases where either the Protocol or a pass/fail criterion is not designated, Protocol 1 shall be used.
