The executable tests of Amade salt spray testers include neutral salt spray test (NSS), acetic acid spray test (AASS) and copper-accelerated acetic acid salt spray test (CASS).
- Neutral salt spray test (NSS): Neutral 5% sodium chloride solution.
- Acetic acid salt spray test (AASS): Acidified 5% sodium chloride solution with the addition of glacial acetic acid.
- Copper-accelerated acetic acid salt spray test (CASS): Acidified 5% sodium chloride solution with the addition of glacial acetic acid and copper chloride.
The neutral salt spray (NSS) test applies to metals and the alloys, metallic coatings (anodic and cathodic), conversion coatings, anodic oxide coatings, the organic coating on metallic materials.
The acetic acid salt spray test (AASS) and copper accelerated acetic salt spray (CASS) are used for testing decorative coatings such as copper nickel-chromium, nickel-chromium and organic coatings on aluminum.
