The test period of the salt spray test chamber should be selected according to the relevant standards of the tested material or product. If there is no standard, it can be decided through consultation by the relevant parties. The recommended test period is 2h, 6h, 24h, 48h, 72h, 96h, 144h, 168h, 240h, 480h, 720h, 100h.
The spraying shall not be interrupted within the prescribed test period, and the salt spray test box may only be opened when a short observation of the sample is required.
If the termination of the test depends on the time at which corrosion begins to appear, the specimen should be checked frequently. Therefore, these samples cannot be tested together with samples that require a predetermined test period.
The samples of the scheduled test period can be visually inspected regularly, but during the inspection process, the surface to be tested cannot be damaged. The time and number of unpacking inspections of the salt spray test box should be as small as possible.
