Salt Spray Testing Apparatus

About Salt Spray Testing Apparatus

Mett-Bio Metallurgical Testing & Services with its state of the art equipment setup consisting of Salt Spray Chamber Complying to the Requirement of ASTM B 117/ ASTM G 85.

Tests are performed in our ISO 17025:2005 NABL accredited lab under the standard Specified conditions or as per specific field conditions.

Salt spray testing is a test method where in a product or coatings resistance to corrosion is evaluated in severe corrosive conditions with extended exposure to a saline or salted spray

This testing is carried out in a closed chamber which is filled neutral salt fog. The test specimen is exposed to a predetermined time period and inspected during its exposure. This test is carried out to check the integrity of coatings, paints in a corrosive environment. This test is carried out as per ASTM B117.

Types of Salt spray testing:

Neutral Salt Spray (NSS),

Acetic acid Salt Spray (ASS),

Copper sulphate Acetic Salt Spray (CASS)

The salt spray test can be acclimatized to suite different corrosivity level to simulate different environments.

The test specimen is exposed to a predetermined time period and inspected during its exposure. This test is carried out to check the integrity of coatings, paints in a corrosive environment. This test is carried out as per ASTM G 85.

A standard 5% salt solution of sodium chloride known as NSS or neutral salt spray and a solution of acetic acid known as ASS. The solutions are chosen based on the type of coating to be evaluated.

Other salt variations: SO₂ / Calcium Chloride (CaCl2)..
