16、 The risk of fire needs to be considered in any electrical circuit. 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, pri
17、marily as victims of fire, may nevertheless contribute to the fire. Fire hazard increases as the burning area increases, leading in some cases to flash-over 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
18、spread of flame. This technical specification describes surface spread of flame test methods in common use to assess electrotechnical products or materials used in electrotechnical products. It forms part of the IEC 60695-9 series which gives guidance to product committees wishing to incorporate tes
19、t methods for surface spread of flame in product standards.
