ISO DIS 11907-1

Description / Abstract: The document defines terms related to smoke corrosivity as well as smoke acidity and smoke toxicity. It presents the scenario-based approach that controls smoke corrosivity. It describes the test methods to assess smoke corrosivity at laboratory scale. It deals with test applicability and post-exposure conditions. This document is applicable to tests of determination of smoke corrosivity from combustion of materials samples.

Clause 3 defines smoke corrosivity as well as smoke acidity and smoke toxicity. Cause 4 details the objectives of this document. Clause 5 presents the scenario-based approach that governs smoke corrosivity. Clause 6 categorizes the different test methods to assess smoke corrosivity at laboratory scale. Clauses 7 and 8 respectively deal with thest applicability and post-exposure conditions.

Any standard method within ISO 11907 should be used solely to measure and describe the properties of materials, products or systems in response to heat or flame under controlled laboratory conditions and should not be considered or used by itself for describing or appraising the fire hazard of materials, products or systems under actual fire conditions or as the sole source on which regulations pertaining to corrosivity of fire effluents are based.
