What is metal coating salt spray test chamber?
Metal coating salt spray test chamber is used to inspect salt corrosion ability of materials and protective layers through simulating ocean climate, compare process quality for similar protective layers.
What kind of materials/products/industries will use metal coating salt spray test chamber?
Automotive, electronic component, metal materials, marine, aerospace and paint/coating, etc.
How many test methods does metal coating salt spray test chamber have?
There are four test methods as following mentioned:
- NSS test (neutral salt spray test) is the widely used accelerated corrosion test method. It adops 5% saline solution with PH value of 6~7, test temperature is 35℃, precipitation of salt spray is 1~2ml/80cm/hr.
- ASS test (acetic acid salt spray test) is developed based on NSS test. Adding some glacial acetic acid into saline solution, and make the PH value of solution to be 3, then solution becomes acidic solution, so does salt fog. Its corrosion speed is 3 times faster than NSS test.
- CASS test(copper-accelerated acetic acid-salt spray test) is a kind of fast salt spray corrosion test, add some copper salt into saline solution, test temperature is 50℃, its corrosion speed is about 8 times than the NSS test.
What kind of test standard does metal coating salt spray test chamber comply with?
- GB/T 2423.17-1993 salt spray test
- GB/T 2423.18-2000 salt spray test
- GB/T 10125-1997 salt spray test
- ASTM.B117-97 salt spray test
- JIS H8502 salt spray test
- IEC68-2-11 salt spray test
- IEC68-2-52 1996 salt spray test
- GB.10587-89 salt spray test
- CNS.4158 salt spray test
- CNS.4159 CASS Accelerated acetic acid copper salt spray test
- GB/T 12967.3-91 CASS Accelerated acetic acid copper salt spray test
1 Entire PP&PVC solid mechanical structure, resistance to hydrochloric acid, heat resistance and never aging, suitable for salt fog copper acetate, etc.
2 Patent nozzle and conical diffusion device makes the fall fog rapidly and evenly. With manual level automatic control mode, the biggest setting time can reach 9990 hours.
3 Have automatic demist device, can clear observe tested products after the experience is finished.
4 Three complete temperature control systems(Saturated air temperature, the temperature in the cabinet, the test liquid temperature) ensure the consistency and standards of the test.

- Test area and saturated pressure barrel can not reach set temperature
1 set temperature is low
2 test area/saturated pressure barrel safety protection switch set temperature is low
3 heating system malfunction
4 electromagnetic relay malfunction
5 controller malfunction
1 set temp. to the wanted temp.
2 set the temp. to the wanted temp.
3/4/5 please contact us to send the new parts if our product is in the warranty, overwarranty is also
available with some charges
- Spray quanity is not enough
1 spray regulator position is low
2 glass nozzle jam
3 pressure value set too low
1 make the spray regulartor higher
2 clean glass nozzle or replace a new nozzle
3 adjust pressure value to 2kg/cm2 using pressure regulating valve
Installation requirement for water and pressure
- Water quality requirement: industrial water or tap water with filter(filtered water PH is 6.5~7.2 ), or use pure water(Attention: mineral water contains minerals and can not use).
- pressure requirement: water pressure 1~3kg to ensure normal filling water.
- interface requirement: water inlet need use hose to connect with seal ring fixed in order to prevent leakage.
