21、INTERNATIONAL ELECTROTECHNICAL COMMISSION _ LUMINAIRES Part 2-24: Particular requirements Luminaires with limited surface temperatures FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (
22、IEC National Committees). The object of IEC is to promote international co-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 Report
23、s, Publicly Available Specifications (PAS) and Guides (hereafter referred 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
24、-governmental organizations liaising with the IEC also participate in this 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
25、 IEC on technical matters express, as nearly as possible, an international 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 a
26、ccepted by IEC National Committees in that sense. While all reasonable efforts 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 interna
27、tional uniformity, IEC National Committees undertake to apply IEC Publications 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
28、 latter. 5) IEC itself does not provide any attestation of conformity. Independent 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
29、should ensure that they have the latest edition of this publication. 7) No 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
30、damage of any nature whatsoever, whether direct or indirect, or for costs (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
31、 of the referenced publications is indispensable for the correct application 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 r
32、ights. International Standard IEC 60598-2-24 has been prepared by subcommittee 34D: Luminaires, of IEC technical committee 34: Lamps and related equipment. This publication is intended to be read in conjunction with IEC 60598-1: Luminaires Part 1: General requirements and tests. This second edition
33、cancels and replaces the first edition published in 1997. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) change of required degree of protection from IP6X to IP4X to harmonize with the international wiri
34、ng rules; b) temperature limits introduced for glass surface of any light source exposed to risk of dust. 4 60598-2-24 IEC:2013 The text of this standard is based on the following documents: FDIS Report on voting 34D/1094/FDIS 34D/1100/RVD Full information on the voting for the approval of this stan
35、dard can be found in the report on voting indicated in the above table. A list of all the parts in the IEC 60598 series, published under the general title Luminaires can be found on the IEC website. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. In this standard
36、, the following print types are used: requirements: roman type. test specifications: italic type. notes: smaller roman type. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in t
37、he data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60598-2-24 IEC:2013 5 LUMINAIRES Part 2-24: Particular requirements Luminaires with limited surface temperatures 24.1 Scope This part of the IEC 60598
38、 series specifies requirements for luminaires intended for use where the necessity of limited temperature on the outer surface exists, due to the risk of thermal effects, combustion or degradation of materials but where the risk of explosion in the atmosphere does not exist. The luminaires are for u
39、se with electric light sources on supply voltages not exceeding 1 000 V. This standard specifically excludes requirements for luminaires for use in explosive gas atmospheres and explosive dust atmospheres. 24.2 Normative references The following documents, in whole or in part, are normatively refere
40、nced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60364-4-42, Low-voltage electrical installations Part 4-42: Protection
