DIN EN ISO 9227 Salt Spray Testing Standard

DIN EN ISO 9227 is a standard for corrosion testing using salt spray. It specifies the equipment, reagents, and testing procedures for assessing the corrosion resistance of metal materials. This standard is unrelated to whether the sample has undergone anti-corrosion treatment.

There are three main salt spray test methods: neutral salt spray test (NSS), acetic acid salt spray test (AASS), and copper accelerated acetic acid salt spray test (CASS).

These tests expose the test samples to a controlled salt spray environment. They are typically used to inspect the corrosion resistance and coating quality of metal parts, surface-treated products, and protective coatings. Salt spray test chambers are used to create and maintain the required test environment.

DIN EN ISO 9227 specifies three methods for salt spray testing. Each method uses a different test solution and is suitable for different materials and protective coatings.
