24、IC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-37: Tests Cable bending for fibre optic closures FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical com

25、mittees (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, Technic

26、al Reports, 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, governmenta

27、l and non-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 agre

28、ements of 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

29、and are accepted 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 promot

30、e international 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 indicat

31、ed in the 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) A

32、ll users 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

33、or other 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 publica

34、tion. Use 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

35、 patent rights. International Standard IEC 61300-2-37 has been prepared by sub-committee 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 2006. This edition constitute

36、s a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) substantial updating of Subclauses 4.1, 6.5, 6.7 and Figure 1; b) addition of severities which are determined by the number and direction of cable bends, test temperatur

37、e and overpressure for each environmental category according to IEC 61753-1. BS EN 61300-2-37:2016 4 IEC 61300-2-37:2016 IEC 2016 The text of this standard is based on the following documents: FDIS Report on voting 86B/3975/FDIS 86B/3981/RVD Full information on the voting for the approval of this st

38、andard 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. A list of all the parts in the IEC 61300 series, published under the general title, Fibre optic interconnecting devices and passive component

39、s Basic test and measurement procedures can be found on the IEC website. 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

40、date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended.

47、C 2016 4 General description 4.1 Device under test (DUT) The DUT is defined as an assembled closure with cable comprising all necessary parts for the required function. Separate DUTs for sealing performance and optical evaluation may be used. The sealing performance DUT shall be provided with an air

48、 pressure test access valve. The length of the cables extending from the DUT shall be at least 1 m. The open ends of the cables shall be sealed. Each applicable cable type with minimum and maximum cable dimensions shall be represented in the test program. Multiple DUTs may be required to accommodate

49、 these cables. The optical evaluation DUT shall be constructed in such a way that it represents all allowed functions of the product. This shall be realised by building optical circuits for each fibre separation level. Each applicable cable type with minimum and maximum cable dimensions shall be represented in the test program. 4.2 Test procedure The DUT shall be securely fixed and placed in a conditioning chamber. The cable shall be subjected to a specified
