Test Background
The purpose of the salt spray test for optical and photonics instruments is to evaluate the ability of the instrument surface and protective coating (plating) layer to resist salt spray, to evaluate the ability of optical and other functional coating (plating) layers to resist salt spray corrosion, to evaluate the anti-salt spray corrosion effect of metal and non-metal coating (plating) layers, and to early detect the irrationality of material combinations.
Zhongke Testing Reliability Experiment Center has environmental testing capabilities for various optical and photonics instruments, and provides professional environmental testing services such as salt spray testing for optical and photonics instrument products.
Scope of tests
All optical and photonic instruments including ancillary components from other fields (such as mechanical, chemical and electronic equipment)
Test method
1. Test device: test chamber (room), atomizing nozzle, level adjustment tank and water supply pipeline, oil and solid matter interceptor and humidifier, sample rack
2. Reagents: test solution, compressed air
3. Test conditions: temperature, salt spray, test interruption and opening of test chamber
4. Test procedures: pretreatment (sample preparation), recovery, and evaluation. If the change in performance and physical appearance of the sample meets the requirements of relevant standards, the evaluation is qualified.
Slight changes in color and/or brightness of the protective coating or slight corrosion are allowed, but there should be no corrosion of the base.
