39、 the adoption and implementation of the recommendations of ISO/TC 92, for the minimization of toxic hazard from fires involving electrotechnical products. Electrotechnical products, primarily as the objects of a fire, may contribute to the fire hazard due to release of toxic effluent, which may be a
40、 significant contributing factor to the overall fire hazard. IEC product committees incorporating requirements for the assessment of toxic hazard from fire in product standards should note that toxic potency and other measurements of toxicity which are described in this international standard should
41、 not be used directly in product specifications. Data from toxic potency test methods should only be used as part of a toxic hazard assessment, in conjunction with other product-based reaction to fire data such as mass loss rate. BS EN 60695-7-2:2011 8 60695-7-2 IEC:2011 FIRE HAZARD TESTING Part 7-2
42、: Toxicity of fire effluent Summary and relevance of test methods 1 Scope This part of IEC 60695 gives a brief 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 scena
43、rios 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. This basic safety publication is intended for use by technical committees in
44、the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements, test method
45、s or test conditions of this basic safety publication will not apply unless specifically referred to or included in the relevant publications. 2 Normative references The following referenced documents are indispensable for the application of this document.
