26、MISSION _ MISCELLANEOUS LAMPHOLDERS Part 2-3: Particular requirements Lampholders for double-capped linear LED lamps FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Commi
27、ttees). 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 Reports, Publicly Availa
28、ble 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- governmental org
29、anizations 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 IEC on technical
30、 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 accepted by IEC Na
31、tional 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 international uniformity
32、, 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 latter. 5) IEC i
33、tself 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 should ensure tha
34、t 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 damage of any nat
35、ure 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 of the reference
36、d 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 rights. Internatio
37、nal Standard IEC 60838-2-3 has been prepared by subcommittee 34B: Lamp caps and holders, of IEC technical committee 34: Lamps and related equipment. The text of this standard is based on the following documents: FDIS Report on voting 34B/1851/FDIS 34B/1857/RVD Full information on the voting for the
38、approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 4 IEC 60838-2-3:2016 IEC 2016 This Part 2-3 is to be used in conjunction with the latest edition of IEC 60838-1 and its am
39、endments. It was established on the basis of the fifth edition (2016) of that standard. A list of all parts in the IEC 60838 series, published under the general title Miscellaneous lampholders, can be found on the IEC website. In this standard the following print types are used: test specifications
40、and compliance statements: in italic type; NOTES: in small roman type. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this da
41、te, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IEC 60838-2-3:2016 IEC 2016 5 MISCELLANEOUS LAMPHOLDERS Part 2-3: Particular requirements Lampholders for double-capped linear LED lamps 1 Scope This part of IEC 60838-2 applies to lampholders for double-c
42、apped linear LED lamps intended for building-in (to be used for general lighting service and with caps as listed in Annex A). Lampholders within the scope of this standard do not include heat management. Double-capped linear LED lamps can also be used with lampholders originally been designated for
43、other technologies. The requirementsfor these lampholders are covered by separate standards. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applie
