What is ISO 21207 – Artificial atmospheres about?
ISO 21207 is an international standard that discusses corrosion tests in artificial atmospheres. An accelerated corrosion test is a necessary and powerful tool when used in Material selection as a relative indicator of corrosion resistance. Examining potential environments for new materials.
ISO 21207 defines two accelerated corrosion test methods to be used in assessing the corrosion resistance of products with metals in environments where there is a significant influence of chloride ions, mainly as sodium chloride from a marine source or by winter road de-icing salt, and of corrosion-promoting gases from industrial or traffic air pollution.
ISO 21207 specifies both the test apparatus and test procedures to be used in executing the accelerated corrosion tests. The methods are especially suitable for assessing the corrosion resistance of sensitive products with metals, e.g., electronic components, used in traffic and industrial environments.
Who is ISO 21207 – Artificial atmospheres for?
ISO 21207 on corrosion tests in artificial atmospheres applies to:
- Laboratory testing
Why should you use ISO 21207 – Artificial atmospheres?
The accelerated corrosion test methods described in ISO 21207, methods A and B are designed to stimulate and enhance the environmental influence of exposure to an outdoor climate where salt-contaminated conditions and corrosion-promoting gases from an industrial or a traffic environment occur which might promote corrosion.
ISO 21207 provides two types of methods for accelerated corrosion tests. Method A simulates a moderately aggressive traffic environment while test method B simulates a more severe industrial or traffic environment.
As a user of ISO 21207, you can ensure the corrosion tests in artificial atmospheres by providing accelerated corrosion tests which involve alternate exposure to corrosion-promoting gases, neutral salt spray and drying.
