BS EN 60695-7-2 is a European standard that discusses the summary and relevance of test methods for the toxicity of fire effluent for fire hazard testing. Toxic fire effluents are responsible for the majority of fire deaths, and an increasingly large majority of fire injuries, driven by the widespread and increasing use of synthetic polymers.
BS EN 60695-7-2 gives a summary of the test methods that are in common use in the assessment of acute toxic potency, and other toxicity tests. It includes special observations on their relevance to real fire scenarios and gives recommendations on their use. It advises which tests provide toxic potency data that are relevant to real fire scenarios, and which are suitable for use in fire hazard assessment and fire safety engineering.
BS EN 60695-7-2 on fire hazard testing applies to:
Fire effluent is a totality of gases and aerosols, including suspended particles, created by combustion or pyrolysis in a fire. Electrotechnical products, primarily as the objects of a fire, may contribute to the fire hazard due to the release of toxic effluent, which may be a significant contributing factor to the overall fire hazard.
BS EN 60695-7-2 provides fire safety engineering in which the application of engineering methods based on scientific principles to the development or assessment of designs in the built environment through the analysis of specific fire scenarios or the quantification of risk for a group of fire scenarios.
Overall, BS EN 60695-7-2 is useful as it provides guidance on the test methods for the toxicity of fire effluent for fire hazard testing.
