31、opy, (c) BSI60695-2-13 IEC:2010 5 INTRODUCTION In electrotechnical equipment, overheated metal parts can act as ignition sources. In glow-wire tests an electrically heated wire is used to simulate such an ignition source. IEC 60695-2-10 describes a glow-wire test apparatus and common test procedure,
32、 IEC 60695-2-11 describes a glow-wire flammability test for end products, and IEC 60695-2-12 describes a glow-wire flammability index test method for materials. In the design of any electrotechnical product, the risk of fire and the potential hazards associated with fire need to be considered. In th
33、is respect the objective of component, circuit, and product design, as well as the choice of materials, is to reduce to acceptable levels the potential risks of fire during normal operating conditions, reasonable foreseeable abnormal use, malfunction and/or failure. IEC/TC 89 has developed IEC 60695
34、-1-10, 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 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
35、fire within the bounds of the enclosure of the electrotechnical product in the event of ignition. Secondary aims of IEC 60695-1-10 and IEC 60695-1-11 include the minimization of any flame spread beyond the products enclosure and the minimization of the harmful effects of fire effluents such as heat,
36、 smoke, toxicity and/or corrosivity. Fires involving electrotechnical products can also be initiated from external non-electrical sources. Considerations of this nature should be dealt with in the overall fire risk assessment. This part of IEC 60695 describes a glow-wire ignition temperature test me
37、thod for materials. It should be used to measure, describe, and rank the properties of materials in response to heat caused by contact with an electrically heated wire under controlled laboratory conditions. This may be useful for the evaluation of materials for use in products that may be exposed t
38、o excess thermal stress such as a fault current flowing through a wire, overloading of components, and/or bad connections. It should not be used to solely describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this te
39、st may be used as elements of a fire risk assessment which takes into account all of the factors pertinent to a fire hazard assessment of a particular end use. This International Standard may involve hazardous materials, operations, and equipment. It does not purport to address all of the safety pro
40、blems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

41、42, Uncontrolled Copy, (c) BSI 6 60695-2-13 IEC:2010 FIRE HAZARD TESTING Part 2-13: Glowing/hot-wire based test methods Glow-wire ignition temperature (GWIT) test method for materials 1 Scope This part of IEC 60695 specifies the details of the glow-wire test to be applied to test specimens of solid
42、electrical insulating materials or other solid materials for ignitability testing to determine the glow-wire ignition temperature (GWIT). The GWIT is the temperature which is 25 K (or 30 K) higher than the maximum test temperature, determined during this standardized procedure, at which the tested m
43、aterial a) does not ignite, or b) if sustained and continuous flaming combustion does not occur for a time longer than 5 s for any single flame event and the specimen is not totally consumed. This test is a materials test carried out on a series of standard test specimens. The data obtained, along w
44、ith data from the glow-wire flammability index (GWFI) test method for materials, IEC 60695-2-12, can then be used in a preselection process in accordance with IEC 60695-1-30 to judge the ability of materials to meet the requirements of IEC 60695-2-11. NOTE As an outcome of conducting a fire hazard a
45、ssessment, an appropriate series of preselection flammability and ignition tests may allow a reduction of end product testing. 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 104 and IS
46、O/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 specifically referre
47、d to or included in the relevant publications. 2 Normative references The following referenced documents are indispensable for the application of this document.
