Résumé : |
This article discusses similar assumptions made about many coating specifications and the trouble the assumptions cause. In the discussion, the toil is in the tests. A side from the use of successful track records, it is common for coating specifications to be based on test criteria deemed important by specification authorities. But are the tests relevant to the intended service environment ? Has the meaning of the test data been misinterpreted ? Have the tests been ascribed a level of accuracy and dependency that the test method simply cannot deliver ? These vital questions, addressed in this article, must be considered if a coating specification is to be supported in a meaningful way and to prevent all sorts of problems. The authors relate tales - from the water storage, Canadian oil patch, and bridge industries - in which specifiers assumed things were in order, where repeated us suggested all was well. But all was not tell. The coating specifications were built upon inappropriate uses of certain test data, and dark consequences loomed. The authors also propose ways to conduct testing that potentially offer more meaningful correlations with real-world coating performance. |
