Corrosion tests to verify the wear resistance of the material, which depends on the level of zinc deposit left on the item. Performed in the Angelantoni DCTC 600 P cabin, it allows to simulate the corrosive action in short times (accelerated aging) through a continuous spray of saline solution (1.2 ml / h on 80 cm² of surface) with humidified air at 35 ° and a PH which varies between 6.5 and 7.2. The processing complies with the DIN 50021 standard corresponding to the UNI ISO 9227 standard.
