The working temperature of the salt spray corrosion test chamber is between room temperature and 55 ℃, and can be kept constant.
In the salt spray test chamber with the specified studio volume, the material or product is subjected to the salt spray corrosion test under the condition of constant relative humidity and temperature.
Placement Method
1.The test sample of the salt spray corrosion test chamber cannot be placed flat under normal circumstances.
It is mentioned in the requirements of the salt spray standard that the test surface of the salt spray test sample should form an angle of 15°~30° with the vertical direction, and an angle of 20° should be formed as far as possible. For irregular samples, it should be as close as possible to the above requirements.

Method 2
2. The test sample is placed in the salt spray test chamber with the test surface facing up, and the salt spray generated by the salt spray test chamber is free to settle and deposit on the test surface of the sample. The salt spray cannot be directly sprayed on the test surface of the sample.
3. The sample support of the salt spray corrosion test chamber is made of glass, plastic and other materials that are resistant to salt spray and acid and alkali corrosion. If the sample needs to be hung on the support, the material for hanging the sample cannot be made of metal material, generally cotton fiber is used. , non-metallic materials such as rayon or other insulating materials.
