Traditionally, people call the corrosion test salt water test machine, salt water sprayer, corrosion aging or salt spray test chamber. Typical salt spray test chamber> Corrosion test method: put the sample into a stable, saturated relative humidity (RH) environment, and for a certain period of time, such as 999H, use 5% NaCI solution as the condensed salt spray , Its temperature is 35 ~ 40s ℃; Another method is called 100% relative humidity method. It is made with water that does not contain salt or any other chemical substances, and is often regarded as a humidity test method. In the early days, the purpose of the salt spray test chamber was to verify the longevity of corrosion, by arranging various degrees of corrosion, or simply classifying the test as a pass or fail test. However, in reality, no one really puts the product in the environmental conditions of 20% brine, 35 ~ 40s ℃, 100% RH. Although there are still many laboratories still adopting this method, its problem is that There is no way to judge the relevance of product service life or end use.
