Scope

This document specifies two accelerated corrosion test methods. These methods assess the corrosion resistance of products containing copper in environments where there is a significant influence of chloride ions, mainly as sodium chloride from a marine source or winter road de-icing salt, as well as the influence of corrosion-promoting gases from industrial or traffic air pollution.
This document 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.
