33、llic and inorganic coatings on metallic substrates can be either anodic or cathodic to the substrate. In rating these coatings for the effects of corrosion, two evaluations shall be made: - the ability of the coating to protect the substrate from corrosion and thus prevent degradation of the base me

34、tal; - the ability of the coating to retain its integrity and thus maintain a satisfactory appearance. Although these functions overlap, they can be evaluated separately in terms of: - a protection rating (Rp) relating to the corrosion of the base metal; - an appearance rating (RA) relating to the d

35、eterioration of the coating. The protection rating (Rp) assigns a number representing the ability of the coating to protect the base metal from corrosion. The appearance rating (RA) assigns a sequence of letters and numbers to the overall appearance of the specimen which includes all deterioration c

36、aused by the corrosion test or environment. NOTE 1 Imperfections on a panel or article before exposure testing should be noted and given due consideration when evaluating the results of the examination. Deliberate imperfections may also be introduced as part of a test programme. The coating system h

NOTE 2 Determination of the anodic and cathodic corrosive mechanisms can be extremely difficult in some cases (chromated zinc on

38、 steel or multiple coatings). For the purposes of this document knowledge of these mechanisms is not necessary.

39、cimens and manufactured articles subjected to corrosion tests 1 Scope This International Standard gives a method of evaluating the condition of decorative and protective metallic and inorganic coated panels or articles which have been exposed to corrosive environments for test or for other purposes.

40、 It is applicable to test panels or components exposed to natural atmospheres, in mobile or static conditions, or subjected to accelerated tests. NOTE 1 Examples of such tests are given in the Bibliography. This International Standard recognizes that the protection rating can be assessed objectively

41、 in accordance with clause 6. However, the assessment of appearance depends on many subjective factors (see 6.2). NOTE 2 The edges of test panels or components may be protected, e.g. by tape or wax (paraffin), if this is an agreed pari of the test and is recorded in the test report. This is essentia

42、l if the specimens are cut from larger pieces and have exposed uncoated edges. 2 Terms and definitions 2.1 protection rating rating number (see Table 1) assigned to the ability of the coating to protect the base metal from corrosion RP 2.2 protection defect defect used to assess the protection ratin

Bliste

46、coating system particular series of deposits including the thickness and type of layers in multilayer deposits and treatments which have been applied to the base metal 2.7 significant surface part of the surface which is essential in the appearance or serviceability of the article and which is to be

47、 covered or is covered by the coating (see clause 5) 3 Principle This International Standard establishes a rating system for evaluating the deterioration of the coating and the base metal due to corrosion. The rating method described in this International Standard is applied to evaluate the appearan

48、ce of the coating, as well the extent of the corrosion on test panels or the significant surfaces of components which have been subjected to performance tests. The result of inspecting a surface, called the performance rating, is recorded as two separate ratings, the protection rating (Rp) and the a

49、ppearance rating (RA). When recording the rating of a surface, the type(s) and severity of defect(s) contributing to the rating shall be noted if this information is required. This information is recorded using agreed symbols for the defects and the extent of these defects. When only the protection rating (Rp) is required, it is permitted to omit the appearance rating (RA). However, in such a case, a written dash should follow the protection rating in order to indicate deliberate omission of the appearance rating. 4 Types of defect It is possible for defects to a
