Describes test methods which measure corrosion damage effects, on targets, of fire effluent from the combustion of test specimens. Both leakage current and metal loss can be measured by using appropriate targets. The decomposition model used in this technical specification is suitable for simulating fire scenarios, such as oxidative non-flaming decomposition, a smouldering fire, a developing fire with flame formation, and a fully developed fire. Deals with different test methods which are not equivalent. The test methods are useful for product development and assessment because they allow the user to evaluate different characteristics of fire effluents, which generally are not correlated. Has the status of a basic safety publication in accordance with IEC Guide 104.
