ABOUT

HISTORY:

Salt Fog testing was originally introduced by ASTM back in 1914 am has evolved today in to ASTM B117-90. It was intended to test the ability of product to survive the corrosive environment found on board ships and tropical islands. The need for a standard test method was further generated by military experience during WWII. 

PURPOSE:

Salt fog climatic chamber tests are performed to determine the resistance of equipment to the effects of an aqueous salt atmosphere. 

ENVIRONMENTAL EFFECTS:

The effects of exposure of materiel to an
environment where there is an aqueous salt atmosphere can be divided into three broad categories: corrosion effects. electrical effects. and physical effects. 

Corrosion effects:

1. Corrosion due to electrochemical reaction. 
2. Accelerated stress corrosion.
3. Formation of acidic/alkaline solutions following salt ionization in water.
