The objective of component, circuit and equipment design, as well as the choice of materials, is to reduce the likelihood of fire, even in the event of foreseeable abnormal use, malfunction or failure: Electrotechnical products, primarily as victims of fire, may nevertheless contribute to the fire. Fire hazard increases as the burning area increases, leading in some cases to flashover and a fully developed fire. This is a typical fire scenario in buildings. It is therefore useful to measure the rate and extent of the surface spread of flame: This partBritish Standard is the UK implementation of IEC 60695-9 describes surface spread of flame test methods in common use to assess electrotechnical products or materials used in electrotechnical produetsEN IEC 60695-9-2:2021. It forms part of the IEC 60695-9 seriesis identical to IEC 60695-9-2:2021. It supersedes BS EN 60695-9-2:2014, which gives guidanee to product committees wishing to incorporate test methods for surface spread of flame in produet standardsis withdrawn. The UK participation in its preparation was entrusted to Technical Committee GEL/89, Fire hazard testing IEC 60695-9 consistsA list of the following parts:organizations represented on this committee can be obtained on request to its committeemanager.
