Defines a test procedure for generation of thermal decomposition products from plastic materials or products in an air stream, and assessing the corrosive effects of these fire effluents on targets. Not intended for use for assessment of the corrosivity hazard of fire atmospheres.

1.1 This part of ISO 11907 specifies a test method for generating thermal decomposition products from plastic materials or products in an air stream and assessing the corrosive effects of these fire effluents on targets. It is not intended that the results be used to assess the corrosivity hazard of fire atmospheres.

1.2 It describes a dynamic decomposition test method for the assessment of the corrosion damage of a standardized target by the change in its electrical resistance.

1.3 The decomposition model is suitable for simulating the main fire scenarios, such as a smouldering fire, a developing fire with flame formation, and a fully developed fire. The decomposition model enables a constant flow of smoke to be maintained throughout the exposure time.

The decomposition model and exposure model enable the potential for a contribution to corrosivity to be estimated.
