30、:2013 5 INTRODUCTION In the design of any electrotechnical product, the risk of fire and the potential hazards associated with fire need to be considered. In this respect the objective of component, circuit, and product design, as well as the choice of materials, is to reduce to acceptable levels th
31、e potential risks of fire during normal operating conditions, reasonable foreseeable abnormal use, malfunction, and/or failure. IEC 60695-1-10 was developed, together with its companion, IEC 60695-1-11, to provide guidance on how this is to be accomplished. The primary aims of IEC 60695-1-10 and IEC
32、 60695-1-11 are to provide guidance on how: a) to prevent ignition caused by an electrically energized component part, and b) to confine any resulting fire within the bounds of the enclosure of the electrotechnical product in the event of ignition. Secondary aims of these documents include the minim
33、ization of any flame spread beyond the products enclosure and the minimization of harmful effects of fire effluents such as heat, smoke, toxicity and/or corrosivity. Fires involving electrotechnical products can also be initiated from external non-electrical sources. Considerations of this nature sh
34、ould be dealt with in the overall fire risk assessment. In electrotechnical equipment, overheated metal parts can act as ignition sources. In glow-wire tests, a glowing wire is used to simulate such an ignition source. This part of IEC 60695 gives recommendations with regard to the glow-wire test ap
35、paratus and describes a common test procedure for tests applicable to end products and materials to be used with IEC 60695-2-11 which describes a glow-wire flammability test for end products (GWEPT), IEC 60695-2-12 which describes a glow-wire flammability index test for materials (GWFI), and IEC 606
36、95-2-13 which describes a glow-wire ignition temperature test method for materials (GWIT). BS EN 60695-2-10:2013 6 60695-2-10 IEC:2013 FIRE HAZARD TESTING Part 2-10: Glowing/hot-wire based test methods Glow-wire apparatus and common test procedure 1 Scope This part of IEC 60695 specifies the glow-wi
37、re apparatus and common test procedure to simulate the effects of thermal stresses which may be produced by heat sources such as glowing elements or overloaded resistors, for short periods, in order to assess the fire hazard by a simulation technique. The test procedure described in this standard is
38、 a common test procedure intended for the small-scale tests in which a standardized electrically heated wire is used as a source of ignition. It is a common part of the test procedures applied to end products and to solid electrical insulating materials or other solid combustible materials. A detail
39、ed description of each particular test procedure is given in the respective standards IEC 60695-2-11, IEC 60695-2-12 and IEC 60695-2-13. This basic safety publication is intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide
40、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 methods or test conditions of this basic safety publication will not apply unless specifical
