Japanese Industrial Standards corrosion

The Japanese Industrial Standard (JIS Z 0103) also defines it as follows. Corrosion is the phenomenon where metals would be attached electrochemically or deteriorated by environmental factors [3].

The dissolution of material into an aqueous solution and so on, has a merit as well as a demerit to the enviroimient. Consider coated materials for an example. One of the objectives of a surface treatment such as plating is to improve corrosion resistance. In this case, it is preferable that the materials do not dissolve in water. This improvement of corrosion resistance enables the long-term use of materials, and will contribute to the reduction of resources and energy required for materials production. In Japan, JIS (Japanese Industrial Standards) H8502 (1999) regulates the methods of corrosion resistance tests for metallic coatings so as to evaluate the corrosion of a material. This standard includes the ISO 4540 (1980), ISO 4541 (1978) and others. 

The overcharge test comes even closer to simulating the actual use of the material. In this test, separators are put into batteries or cells and the cells are overcharged to make sure the oxidizing species are present and controlled at an elevated test to accelerate the rates of reaction. Like the Perox 80 test, separators are removed from the cells at different time intervals so the mechanical properties can be evaluated and the rate of decay curves can be developed and compared. Another similar test is the Japanese Industrial Standards (JIS) corrosion test, in which a test separator is placed between two large lead blocks in an acidic solution [14]. A constant voltage is...
