As an important test equipment for adaptability and reliability, the salt spray test chamber is also used in a wide range of fields, such as: defense industry, light industry electronics, instrumentation, automobile and motorcycle, machinery and other industries.
In the case of the automobile and motorcycle industry, the salt spray test chamber is used for the corrosion test of samples and batch inspection of integrally painted car bodies, body steel plates, components and components with different corrosion-resistant protective coatings. It is used to check the corrosion characteristics and evaluate the corrosion protection measures under static load.
Regarding the different climate and / or corrosion load of the salt spray test chamber, a cyclic alternating combination: composed of a test cycle period
——4 hours salt spray test according to DIN 50 021-SS
——Placed under standard climatic conditions for 4 hours, DIN 50 104-23 / 50-2 (including cooling stage)
——16 hours wet-heat-Storage test, the climatic conditions are in accordance with DIN 50 017-KK (40 ± 3) ℃; 100% air humidity
After 5 cycles of testing, according to the standard climate DIN 50 014-23 / 50-2 requirements, arrange a 2-day rest period. Using this test method, the corrosion characteristics that occur through salt moisture and temperature under static load are evaluated.
Under these clarified corrosion conditions, different corrosion protection coatings can be compared and evaluated. A related connection of the principle of corrosion in a real vehicle cannot be mandatory, because the damage manifestation and corrosion process appearing on the car are a comprehensive method, and the alternating corrosion load phenomenon is not fully grasped and reflected
