26、ensions of optical circuit boards 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 co-operation on all questions

27、 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 to as “IEC Publication(s)”)

28、. 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 this preparation. IEC collabora

29、tes 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 international consensus of opinion on th

30、e 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 efforts are made to ensure tha

31、t 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 Publications transparently to the m

32、aximum 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. Independent certification bodi

33、es 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) No liability shall attach to

34、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 (including legal fees) and

35、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 application of this publication. 9)

36、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 62496-2-2 has been prepared by IEC technical committee 86: Fibre op

37、tics. The text of this standard is based on the following documents: FDIS Report on voting 86/378/FDIS 86/385/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 t

38、he ISO/IEC Directives, Part 2. A list of all parts of the IEC 62496 series, published under the general title Optical circuit boards, can be found on the IEC website. 62496-2-2 IEC:2011 5 The committee has decided that the contents of this publication will remain unchanged until the stability date i

39、ndicated 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. IMPORTANT The colour inside logo on the cover page of this publication indicates that i

40、t contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 6 62496-2-2 IEC:2011 OPTICAL CIRCUIT BOARDS Part 2-2: Measurements Dimensions of optical circuit boards 1 Scope This part of IEC 6249

47、4 Measurement condition All the measurements are made under the conditions specified in IEC 60068-1, unless otherwise specified. Measurements may be made under different conditions to the standard conditions if the standard conditions are difficult to achieve, as long as the actual measurement condi

48、tion does not give rise to any doubt as to the result of the measurement. 5 Objects to be measured and their procedures Objects to be measured as dimensions of OCB are stated in IEC 62496-4. The objects and their methods are summarized in Table 1. This standard specifies mainly mechanical procedures
