EN ISO 10289:2001 )E(9991:98201 OSI OSI iv Introduction The rating method described in this International Stan
32、dard recognizes that decorative and protective metallic 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 corr
33、osion and thus prevent degradation of the base metal; 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;
34、an appearance rating (RA) relating to the deterioration 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
35、specimen which includes all deterioration caused by the corrosion test or environment. NOTE 1Imperfections 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
36、 of a test programme. The coating system has to be known and reported if this rating system is applied. It is especially important to know, if possible, whether the coating is anodic or cathodic to the base metal. NOTE 2Determination of the anodic and cathodic corrosive mechanisms can be extremely d
37、ifficult in some cases (chromated zinc on steel or multiple coatings). For the purposes of this document knowledge of these mechanisms is not necessary. EN ISO 10289:2001 DRADNATS LANOITANRETNI OSI)E(9991:98201 OSI 1 Methods for corrosion testing of metallic and other inorganic coatings on metallic
38、substrates Rating of test specimens 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 fo
39、r test or for other purposes. It is applicable to test panels or components exposed to natural atmospheres, in mobile or static conditions, or subjected to accelerated tests. NOTE 1Examples of such tests are given in the Bibliography. This International Standard recognizes that the protection rating
40、 can be assessed objectively in accordance with clause 6. However, the assessment of appearance depends on many subjective factors (see 6.2). NOTE 2The edges of test panels or components may be protected, e.g. by tape or wax (paraffin), if this is an agreed part of the test and is recorded in the te
41、st report. This is essential if the specimens are cut from larger pieces and have exposed uncoated edges. 2 Terms and definitions 2.1 protection rating Rp rating number (see Table 1) assigned to the ability of the coating to protect the base metal from corrosion 2.2 protection defect defect used to
42、assess the protection rating, including crater corrosion, pin-hole corrosion, corrosion stain due to corrosion from the substrate, blisters and other defects that involve base metal corrosion NOTE Blisters on electroplated aluminium and zinc alloy die castings usually signify base metal corrosion, b
43、ut the inspectors judgement may be required to decide whether a blister does or does not arise at the substratecoating interface. 2.3 appearance rating RA rating number and symbols (see Table 2) assigned to describe the overall appearance of the specimen, including all defects caused by exposure 2.4
44、 appearance defect defect that detracts from the appearance of the specimen (see Table 2) EN ISO 10289:2001 )E(9991:98201 OSI OSI 2 2.5 performance rating combination of the protection rating number (Rp) followed by a slash mark followed by the appearance rating number (RA), i.e. Rp/RA 2.6 coating s
45、ystem 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 covered
46、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 appearance of the
47、 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 appearance
48、 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 (R
49、p) 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 affect both the protection rating (Rp) and the appearance rating (RA). In this rating system, the protection rating is a simple numerical rating while the appearance rating is permitted to include specific defects along with a numerical rating designating the intensity.
