This International Standard provides principles for characterizing the measured production of toxic gases from a laboratory fire test and provides bases for comparing the results between different types and scales of such tests. This Standard also includes consideration of the uncertainties in the gas determinations. The combined uncertainty is a key factor in the ability to establish similarity or difference of test results. The sufficiency of the agreement between a bench-scale test and a real-scale test depends on the precision needed in the fire hazard or risk assessment. This is not covered in this Standard. This International Standard defines the relevance and significance of toxic gas data from measurements in different fire tests. With such a definition it is possible to provide generic guidance on how such data can be compared between different sizes and types of fire tests. The combustion conditions represented by the fire test, other specific characteristics of the test and the test specimen, the sampling strategy of the fire effluents, and the analysis technique for the toxic gas species are the most important factors when defining the significance of the toxic gas data. This International Standard is intended to serve as a tool for: (i) definition of the relevance and significance of toxic gas data from fire tests, (ii) the comparison of toxic gas data from fire tests of different scales and characteristics, and (iii) the prediction of toxic gas data from a large-scale test based on small-scale data or vice versa. This International Standard gives general guidance regarding comparison of toxic gas data between physical fire models of different scales, but is principally developed for the gases listed in ISO 13571, i.e., carbon dioxide (CO2), carbon monoxide (CO), hydrogen halides (HCl, HBr, HF), sulphur dioxide (SO2), hydrogen cyanide (HCN), nitrogen oxides (NO, NO2), formaldehyde (CH2O) and acrolein (C3H4O).
