Salt spray test chamber is the most reliable equipment for checking corrosion resistance of surface coatings when exposed to a salt-laden environment. This time-tested product has been specifically designed to assess the rust-proof ability of components to withstand corrosion due to atmospheric conditions. It provides complete flexibility in simulation of real life weathering conditions.
The temperature range for salt spray is 5°C above ambient temperature up to +55°C.
Salt spray test chamber is suitable for standard salt/fog testing in accordance with DIN EN ISO 9227 (DIN 50021),ASTM B117 and similar international test standards, and can be used with pH neutral salt solutions (NSS) or those acidified by the addition of Acetic Acid (ASS) or Cupric Acid (CASS).
Salt Spray chambers are commonly used to evaluate the corrosive properties of:
Phosphated surfaces (with subsequent paint/primer/lacquer/rust preventive).
Zinc and Zinc-alloy plating (see also electroplating).
Electroplated chromium, nickel, copper and tin.
Coatings not applied electrolytically (such as zinc flake coatings).
Organic Coatings.
Paint Coating.
