ISO 9227 testing
The 6NAPSE Group carries out ISO 9227 testing in artifial atmospheres such as neutral salt spray (NSS), acetic (AASS) and cupro-acetic (CASS).
What is ISO 9227?
ISO 9227 is an international standard that specifies the apparatus, reagents, and procedures to be used for conducting accelerated corrosion tests in artificial atmospheres. Specifically, it describes neutral salt spray (NSS), acetic acid salt spray (AASS), and copper-acetic acid salt spray (CASS) tests.
ISO 9227 Salt Spray Corrosion Test
The 6NAPSE Group conducts salt spray corrosion tests in accordance with the ISO 9227 standard. Our laboratory evaluates the corrosion resistance of metallic materials, with or without temporary or permanent corrosion protection. We also detect discontinuities (pores, defects) in certain coatings.
Specified test types:
- NSS (Neutral Salt Spray) test: neutral salt spray (pH between 6.5 and 7.2).
Applicable to metals and their alloys, metallic coatings (anodic and cathodic), conversion coatings, anodic oxide coatings, and organic coatings on metallic materials. - AASS (Acetic Acid Salt Spray) test: acetic acid salt spray (NSS solution with glacial acetic acid, pH between 3.1 and 3.3).
Particularly useful for testing decorative coatings of copper + nickel + chromium or nickel + chromium, as well as anodic coatings on aluminum. - CASS (Copper-Accelerated Acetic Acid Salt Spray) test: copper-acetic acid salt spray (NSS solution with added copper chloride dihydrate and acetic acid, pH between 3.1 and 3.3, higher temperature: 50°C ± 2°C).
Useful for testing decorative coatings of copper + nickel + chromium or nickel + chromium, as well as anodic and organic coatings on aluminum.
