GB/T 20853-2007 Corrosion of metals and alloys—Corrosion in artificial atmosphere—Accelerated corrosion test involving exposure under controlled conditions of humidity cycling and intermittent spraying of a salt solution
Abstract
This standard details the test methods for the corrosion resistance of metals in environments containing chloride ions, with chloride ions primarily originating from the ocean and road de-icing salts (sodium chloride). This standard specifies the equipment and test procedures used for accelerated corrosion testing, which simulates atmospheric corrosion conditions in a highly controlled manner. The metals covered by this standard include both corrosion-resistant and non-corrosion-resistant materials. This laboratory accelerated corrosion test is applicable to: - Metals and their alloys; - Metal coatings (anodic and cathodic); - Chemical conversion coatings; - Organic coatings on metals. It is particularly suitable for comparative tests to optimize surface treatment methods.
