Salt spray testing for evaluating the corrosion durability of a metallic material with or without corrosion protection.
Examination according to DIN EN ISO 9227 CASS copper accelerated acetic acid-saline solution with pH-value between 3.0 and 3.1. For decorative copper-nickel-chrome or nickel-chrome coatings and anodic coatings on aluminum
Examination according to DIN EN ISO 9227 NSS saline solution with neutral pH-value between 6.5 and 7.2. For metals and their alloys, cathodic or anodic metal coatings, conversion layers, organic coatings on metals.
Norm: DIN EN ISO 9227, DIN EN ISO 6270-2, DIN EN ISO 11997, MIL 810, ASTM B112, ASTM B368, VDA 621-415, DIN EN 60068-2-52, BMW AA-0324
In order to test corrosion resistance of stainless steels and alloys according to ASTM G 48, specimens are exposed to aqueous 10 % iron-III-chloride solution. During a test duration of up to 72 h and a temperature of 20 to 50 °C the weight-loss or formation of pits and crevices is determined via method A or B. The critical pitting temperature (CPT-value) is determined via method C.
