Wooden standards specify the exposure in the corrosive environment After testing or exposure to other purposes, the decorative and protective metal and inorganic coverage layer assessment methods covering the test board or test parts corrosion state.
The method stipulated in this standard is suitable for test boards or test parts exposed under dynamic or static conditions in natural atmosphere, and also applicable to test boards or test parts that accelerate the test.
Whether the metal matrix is decorative or cathode on the metal substrate, and protective metal > and inorganic coverage layer are suitable for The rating method described in this standard. The corrosion resistance rating of these coverage layers should be performed from two aspects:
The capacity of the coverage layer protective substrate from corrosion and destruction;
The cover layer maintains its ability to integrate and maintains satisfaction.
This standard proposes a rating system for evaluation covering layers and corrosion of matrix metals. The rating method described in this standard is used to evaluate the degree of corrosion after the appearance of the cover layer, as well as the main surface of the test board or the test parts.
Use protection rating (RP) and appearance rating (RA). These two independent rating to record the surface inspection results are called performance rating.
When the surface rating of the sample is recorded, if the type and severity of the defect need to be represented, the agreed defect type code and the defect The degree code to record this information. >
When only protecting rating (RP), the appearance rating (RA) is allowed. The method is to connect a short horizontal line (RP/-) after protecting the rating to indicate that the appearance rating is omitted.
AOTSI salt fog test box, also known as salt water spray test machine, salt fog test machine, salt fog test box three defense One of the test equipment of salt fog, mold) test equipment is an important advantage of researching machinery, defense industry, light industrial electronics, instrumentation and other industries such as various environmental adaptability and reliability: Good sex; the test time is significantly shortened; it saves a lot of manpower, financial resources, and material resources, which is widely used in electronics, electrical and automobiles, aviation, military equipment, hardware tools and other products, components, metal materials and products, plating and coating of products and products Layer and other salt mist corrosion test >.
