19、art 20-3: Fire hazard tests Test 20c: Flammability, glow-wire FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international c

20、o-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred

21、 to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in thi

22、s preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an internationa

23、l consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable ef

24、forts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publica

25、tions transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. In

26、dependent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) N

27、o liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs

28、 (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct applicat

29、ion of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60512-20-3 has been prepared by subcomm

30、ittee 48B: Connectors, of IEC technical committee 48: Electromechanical components and mechanical structures for electronic equipment. This standard cancels and replaces Test 20c of IEC 60512-9, issued in 1992. The structure of IEC 60512 series is explained in IEC 60512-1-100. The text of this stand

31、ard is based on the following documents: FDIS Report on voting 48B/2161/FDIS 48B/2196/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. 60512-20-3 IEC:2010 3 This publication has been drafted in accordance with the

32、 ISO/IEC Directives, Part 2. A list of all parts of the IEC 60512 series, under the general title Connectors for electronic equipment Tests and measurements, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability dat

33、e indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 4 60512-20-3 IEC:2010 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Par

34、t 20-3: Fire hazard tests Test 20c: Flammability, glow-wire 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing connectors within the scope of technical committee 48. It may also be used for similar devices when specified in a detail specificatio

35、n. The object of this standard is to detail a standard test method to determine the flammability of a connector when exposed to a glow-wire test under specified conditions. The glow-wire test simulates thermal stresses which may be produced by such sources of heat or ignition as, for example, glowin

36、g elements or overloaded components, for short periods, in order to assess by a simulation technique the fire hazard or burning of a single electronic component. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, on

37、ly the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

38、 Part 2-11: Glowing/hot-wire based test methods Glow-wire flammability test method for end-products 3 Preparation of the specimen The specimen shall consist of an unwired connector, mounted and provided with contacts as specified in the detail specification. 4 Test method The test shall be carried o

39、ut in accordance with IEC 60695-2-10 and IEC 60695-2-11. A wooden board covered with a single layer of tissue paper shall be placed underneath the specimen to be tested as described in IEC 60695-2-10. The position of the specimen and the place of application of glow-wire shall be as specified in the

40、 detail specification. The glow-wire consists of a specified loop of nickel/chromium (80/20) wire 4 mm diameter. A sheathed fine-wire thermocouple, having an overall diameter of 0,5 mm and wires of NiCr and NiAl with the welded point located inside the sheath, is used for measuring the temperature o

41、f the glow-wire. The glow-wire with the thermocouple is shown in Figure 1. 60512-20-3 IEC:2010 5 The test apparatus shall be so designed that the glow-wire is kept in a horizontal plane and a force of 0,8 N to 1,2 N is applied to the specimen, the force being maintained at this value when the glow-w

42、ire or the specimen is moved horizontally one towards the other over a distance of at least 7 mm. The temperature of the tip of the glow-wire and the duration of its application shall be specified in the detail specification.

45、emoval of the glow-wire, the specimen shall preferably not continue to burn. If it continues to burn, the burning time shall not exceed the maximum limit specified in the detail specification. In no case shall any material drops ignite the underlying tissue paper. 6 Details to be specified When this

46、 test is required by the detail specification, the following details shall be specified: a) number and variant of the specimens to be tested; b) mounting of the specimen; c) severity (duration of the application of the glow-wire); d) point of application of the glow-wire; e) maximum burning time; f)

47、 temperature of the glow-wire tip: g) any deviation from the standard test method and/or conditions. _ 8 60512-20-3 CEI:2010 COMMISSION LECTROTECHNIQUE INTERNATIONALE _ CONNECTEURS POUR QUIPEMENTS LECTRONIQUES ESSAIS ET MESURES Partie 20-3: Essais relatifs aux risques du feu Essai 20c: Inflammabilit
