ISO 22479 Corrosion of Metals and Alloys - Testing for Sulfur Dioxide in a Humid Atmosphere (Fixed Gas Method)

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 22479 testing. This standard specifies a method for assessing the resistance of materials or products to a humid atmosphere containing sulfur dioxide.

ISO 22479 Corrosion of Metals and Alloys - Testing for Sulfur Dioxide in a Humid Atmosphere (Fixed Gas Method)

This method is applicable to testing metals and alloys, metallic and non-organic coatings, and organic coatings. All components in contact with sulfur dioxide in a humid atmosphere must be made of corrosion resistant materials and must not themselves emit any gases or vapors likely to affect the corrosion of test specimens.

The preferred capacity of the test chamber is (300 ± 10) 1. Other capacities may be used when agreed between the parties involved. In these cases, the size or number of test samples, the volume of the gas and the amount of water should be adjusted accordingly according to the capacity of the test cabinet.

The upper part of the cabinet shall be designed in such a way that the condensed water droplets formed on its surface do not fall on the test specimens under test. A slope of approximately 12° or more to the horizontal plane of the top of the test cabinet provides adequate protection.

Test specimens may be placed at different levels in the cabinet as long as the solution does not drip onto other test specimens placed one level below the test specimens or their supports.
