What is ISO 29903 ‑ 1 about?
ISO 29903 ‑ 1 is the first part of the ISO 29903 multi-series. ISO 29903 ‑ 1 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. It also includes consideration of the uncertainties in the gas determinations. The combined uncertainty is a key factor in the ability to establish similarities or differences in 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, which is not covered by ISO 29903 ‑ 1 .
ISO 29903 ‑ 1 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.
