In contrast to evaluate the corrosion resistance under outdoor salt pollution/acid rain environment with or without water for a long time or temporary corrosion protection of metallic materials. Standard also provides the test equipment. This method includes two test specimens are exposed to acid salt spray cycle, "dry " and " wet" test conditions.

GB/T 24195-2009/ISO 16151.2005IntroductionCorrosion of metallic material, with or without corrosion protection, the environment will be affected by many factors, the impact depends on the metal material The kind and the type of environment. Since the laboratory impossible to design that contains all of the environmental factors that affect the corrosion accelerated corrosion test Inspection, so laboratory tests are used to simulate the impact of several major environmental factors on the corrosion of metallic materials. May promote lower metal material is exposed to acid rain and salt contamination of the outdoor climatic conditions of corrosion, accelerated corrosion test mentioned in this standard Test method is to simulate this environment and accelerate corrosion on metallic materials. The development of standards to technical papers and reports for reference (See References). Test methods include the sample is exposed to acid salt spray cycle, dry conditions and wet conditions. Test method is mainly used for comparative tests, test The results do not represent the whole of this metal in the actual working environment of the final corrosion resistance, however, the material is exposed to a salt similar test conditions Pollution/acid rain environment relative corrosion resistance, this test method can provide valuable information. GB/T 24195-2009/ISO 16151.2005 Corrosion of metals and alloys Acid salt spray, "dry" and "wet" conditions Cyclic accelerated corrosion test1 ScopeThis standard specifies two accelerated corrosion test methods. Method A and Method B, in the comparative evaluation of outdoor salt pollution/acid rain environment with With or without permanent or temporary corrosion protection corrosion properties of metal materials. Standard also provides test equipment. These two test methods Including sample loop is exposed to acid salt spray, "dry" and "wet" test conditions. Neutral salt spray test (NSS) of the test with conventional accelerated corrosion test, such as GB/T 10125-1997 provisions compared to its maximum The advantage is that it can better simulate corrosion occurred in the outdoor salt pollution/acid rain environment. These two methods of evaluation of corrosion appearance is also very it works. A method is suitable for. --- Metals and their alloys; --- Metal coating (cathode coating); --- Anodized coating; --- Organic coatings on metallic materials. Method B Applicable to. --- Anode coating on a steel plate; Conversion Coatings anodic coatings on steel with ---.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms.
