The salt spray test chamber uses a certain concentration of salt solution or acidic salt solution to conduct accelerated salt spray corrosion tests at a certain temperature and under a certain relative humidity environment through the method of salt spray. So, how to place the sample in the test box when doing the salt spray test? The method is as follows:
2. The test sample is placed in the salt spray test box with the test surface facing upwards. The salt spray generated during the spray of the test box freely settles and deposits on the test surface of the sample. The salt spray cannot be directly sprayed on the test surface of the sample.
3. Under normal circumstances, the test sample should be placed flat. However, the test surface of the salt spray test sample should be 15 ° ~ 30 ° from the vertical direction, and as far as possible 20 °. For irregular samples (such as the entire workpiece), it should also be as close as possible to the above requirements.
4. The test samples can be placed on different horizontal surfaces in the salt spray test box, but they must not touch the box or contact each other. The distance between the test samples shall not affect the free fall of the salt spray on the test surface, and the salt spray droplets collected on the test sample shall not drip onto other test samples. For a new salt spray test with a test period exceeding 96 hours, the sample can be shifted.
Note: The sample holder 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 holder, then the material of the suspended sample cannot be made of metal. Generally, cotton fiber and artificial fiber Or other non-metallic materials such as insulating materials.
