What is ISO 22479-Corrosion of metals and alloys about?
ISO 22479 discusses the corrosion of metals and alloys.
ISO 22479 specifies a method for assessing the resistance of materials or products to a humid atmosphere containing sulfur dioxide. This method is applicable to testing metals and alloys, metallic and non-organic coatings and organic coatings.
Who is ISO 22479-Corrosion of metals and alloys for?
ISO 22479 on sulfur dioxide test in a humid atmosphere is beneficial for:
- Metallurgists
- Testing laboratories
- Civil engineers
Why should you use ISO 22479-Corrosion of metals and alloys?
A humid atmosphere containing sulfur dioxide induces corrosion of many metals. ISO 22479 provides you with a test method that helps you recreate field conditions for sulfur dioxide-based corrosion in metals. The test method described in ISO 22479 helps you to identify the corrosion resistance of metals and alloys to sulfur dioxide.
What’s changed since the last update?
BS ISO 22479:2019 cancels and replaces ISO 3231:1993 and ISO 6988:1985, which have been combined and technically revised. The main changes compared with the previous edition are as follows:
- The method of generating sulfur dioxide from reagents has been deleted because of the risk of exposure to toxic chemicals
