The placement of the sample in the salt spray test chamber is very important. Incorrect placement will affect the results of the entire test. Users are requested to carefully review the test requirements described below.
1. The sample should not be placed in a position where salt spray is directly sprayed.
2. The placement angle of the sample surface in the salt spray test chamber is very important. In principle, the sample should be laid flat. In the salt spray test chamber, the surface to be tested is 15 ° to 25 ° from the vertical, 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 regulations.
3. The sample can be placed on different horizontal surfaces in the box, but it can not touch the box body or each other. The distance between the samples shall not affect the free fall of the salt spray on the surface of the test, and the droplets on the sample or its support shall not fall on other samples. For new inspections or tests with a total test period exceeding 96h, the sample may be allowed to shift.
4. The sample holder is made of inert non-metallic materials. The material of the hanging sample can not be metal, but man-made fiber, cotton fiber or other insulating materials should be used.
