Résumé : |
Adhesion testing should be performed for one of two basic reasons :
- If the specification calls for it as a qualifying test for acceptance of the coating system, or
- If there is failure or suspected failure in the coating system (material and/or methods) that cannot be evaluated (or fully evaluated) by non-destructive methods.
One must always keep in mind that an adhesion test is a destructive test, so the resulting test area now becomes a repair that could, in itself, fail. This is especially important to keep in mind in the case of linings or any system that will be in immersion service, mechanical service, or a chemical/harsh environmental service.
Because it may be necessary to perform adhesion testing in multiple areas (depending on the size of the suspected areas), there will be multiple repairs. Destructive testing should always be the last method employed, not the first method, when evaluating a coating for suspected or obvious failure. |
