Sulfur dioxide salt spray corrosion test box [latest quotation] Annai instrument hydrogen sulfide gas corrosion test box, mixed gas corrosion test box, carbon dioxide test box
Sulfur dioxide corrosion test box is used to test the plating protective coatings of electrical and electronic products, plating products and various gold and silver products. It is used to test the anti-corrosive gas ability of materials and protective coatings, and to compare the process quality of similar protective coatings.
Sulfur dioxide corrosion test box can satisfy the cyclic test effect of sulfur dioxide and oxygen in relative humidity storage. Sulfite is used to accelerate the corrosion of materials or products, and the damage degree of materials or products in a certain time range is tested.
Sulfur dioxide corrosion test box is used to test the anti-sulfur dioxide ability of materials and protective coatings, and to compare the process quality of similar protective coatings. It is a kind of test equipment to simulate the corrosion environment artificially.
Reference Standard for Sulfur Dioxide Corrosion Test Box
Sulfur dioxide corrosion test box is manufactured in strict accordance with national standard GB/9789-88 "Sulfur dioxide corrosion test under normal condensation of metal and other non-organic coatings" and international standard ISO6988 issued by China; German standard DIN 50018 "Sulfur dioxide corrosion test under saturated environment" GB2423.19-81 "Dioxide of electrical and electronic products" Standards for sulphur test and other international standards currently in use for sulphur dioxide and hydrogen sulfide gas corrosion.
