the ability of product to survive the corrosive environment found on
ships and tropical islands. The need for a standard test method was
generated by military experience during WWII.
climatic chamber tests are performed to
determine the resistance of equipment to the effects of an aqueous salt
The effects of
exposure of materiel
environment where there is an aqueous salt atmosphere can be divided
broad categories: corrosion effects. electrical effects. and physical
- Corrosion due
to electrochemical reaction.
- Formation of
acidic/alkaline solutions following salt
ionization in water.
