23、 AND PASSIVE COMPONENTS ADAPTORS FOR FIBRE OPTIC CONNECTORS Part 1: Generic specification 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 i
24、s 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 Available Specifications (PAS) an
25、d 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 organizations liaising with the
26、 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 matters express, as nearly
27、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 National Committees in that se
28、nse. 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, IEC National Committees un
29、dertake 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 itself does not provide any a
30、ttestation 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 that they have the latest editi
31、on 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 nature whatsoever, whether dire
32、ct 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 referenced publications is indispensa
33、ble 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. International Standard IEC 61274-1 has
34、 been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This third edition cancels and replaces the second edition published in 2007, and constitutes a technical revision. The specific technical changes from the pre
35、vious edition include removal of quality assessment procedure, to add the definition of plug-socket configuration, to reconsider a drawing showing the relationship between IEC 60874, IEC 61753, IEC 61754 series of standards, and updating the normative references. 61274-1 IEC:2011 5 The text of this
36、standard is based on the following documents: FDIS Report on voting 86B/3273/FDIS 86B/3305/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. This publication has been drafted in accordance with the ISO/IEC Directiv
37、es, Part 2. A list of all parts of the IEC 61274 series, under the general title Fibre optic interconnecting devices and passive components Adaptors for fibre optic connectors can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until
38、 the stability date 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. 6 61274-1 IEC:2011 INTRODUCTION This part of IEC 61274 is divided
39、into four clauses. Clauses 1, 2 and 3 contain general information pertaining to this generic specification. Clause 4 is entitled “Requirements“ and contains all the requirements to be met by adaptors covered by this standard. This includes requirements for classification, the IEC specification syste
40、m, documentation, materials, workmanship, quality, performance, identification and packaging. NOTE Clauses 1 to 4 are applicable generally and refer to all adaptor standards. 61274-1 IEC:2011 7 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS ADAPTORS FOR FIBRE OPTIC CONNECTORS Part 1: Gen
41、eric specification 1 Scope This part of IEC 61274 applies to fibre optic adaptors for all types, sizes and structures of optical fibre connectors. It includes: adaptor requirements; quality assessment procedures. This standard does not cover test and measurement procedures, which are described in th
42、e IEC 61300 series. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
