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
