The salt spray test chamber can evaluate the salt spray corrosion resistance of materials and their protective layers, as well as the process quality of similar protective layers. At the same time, the ability of some products to resist salt spray corrosion can be evaluated. The products are used for parts and electronics. Salt spray corrosion test of components, protective layers of metal materials and industrial products. However, in the daily test, the climate of the salt spray test chamber is also a certain statement, as follows:
The standard climate simulated by the salt spray chamber is a constant climate with specified temperature and air humidity, a defined air pressure range and air flow rate, and no major additional components and radiation effects. Standard climates may acquire and maintain temperature and humidity sensitive objects. In a specific state. The standard climate corresponds to the average climatic conditions of the salt spray test chamber and may also be adjusted in the test chamber.
The standard climate with an air temperature of 23 degrees, a relative air humidity of 50% (23/50) and a limit deviation according to the accuracy grade is: Standard Climate (Normalklima) DIN 50 014-23/50-1
During the adjustment to the standard climate of the salt spray test chamber, it should be noted that the object corresponds to its state, size and physical and chemical properties require sufficient storage duration to reach its equilibrium state. It is necessary to consider the hysteresis-process and the use of corresponding material inspection standards.
