33、TRODUCTION 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, IEC 60695-2-11 describes a glow-wir

34、e 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 this respect the objective of componen

35、t, 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 60695-1-10, together with its companion,

36、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 fire within the bounds of the enclos

37、ure 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, smoke, toxicity and/or corrosivity.

38、 This International Standard may involve hazardous materials, operations, and equipment. It does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the app

39、licability of regulatory limitations prior to use. !Fires involving electrotechnical products can also be initiated from external non-electrical sources. Considerations of this nature should be dealt with in the overall fi re hazard assessment.“!This part of IEC 60695 describes a glow-wire ignition

40、temperature test method 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 th

41、at may be exposed to excess thermal stress such as a fault current fl owing through a wire, overloading of components, and/or bad connections. It should not be used to solely describe or appraise the fi re hazard or fi re risk of materials, products, or assemblies under actual fi re conditions. Howe

42、ver, results of this test may be used as elements of a fi re hazard assessment which takes into account all of the factors which are pertinent to a particular end use.“BS EN 60695-2-13:2010+A1:2014 60695-2-13 IEC:2010+A1:2014 6 FIRE HAZARD TESTING Part 2-13: Glowing/hot-wire based test methods Glow-

43、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 electrical insulating materials or other solid materials for ignitability testing to determine the glow-wire ignition tempera

44、ture (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 material a) does not ignite, or This test is a materials test carried out on a series of standard test specimens. The data obt

45、ained, along with 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

46、 fire hazard assessment, 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 Gu

47、ide 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 specif

48、ically referred to or included in the relevant publications. 2 Normative references The following referenced documents are indispensable for the application of this document.
