35 FOREWORD
36 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
37 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
38 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
39 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
40 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
41 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
42 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
43 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
44 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
45 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
46 consensus of opinion on the relevant subjects since each technical committee has representation from all
47 interested IEC National Committees.
48 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
49 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
50 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
51 misinterpretation by any end user.
52 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
53 transparently to the maximum extent possible in their national and regional publications. Any divergence between
54 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
55 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
56 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
57 services carried out by independent certification bodies.
58 6) All users should ensure that they have the latest edition of this publication.
59 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
60 members of its technical committees and IEC National Committees for any personal injury, property damage or
61 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
62 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
63 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
64 indispensable for the correct application of this publication.
65 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
66 rights. IEC shall not be held responsible for identifying any or all such patent rights.
67 International Standard IEC 61300-2-37 has been prepared by sub-committee 86B: Fibre optic
68 interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
69 This fourth edition cancels and replaces the third edition published in 2016. This edition
70 constitutes a technical revision.
71 This edition includes the following significant technical changes with respect to the previous
72 edition:
73 a) changed title from cable bending for fibre optic closures to cable bending for fibre optic
74 protective housings;
75 b) broadened the application to all protective housings (closures, boxes, terminals, street
76 cabinets, and optical distribution frame modules);
77 c) changed limit of force for bending cable from 500 N to 100 N;
78 d) included free breathing protective housings.

FDIS Report on voting
86B/xxxx/FDIS 86B/xxxx/RVD
82 Full information on the voting for the approval of this standard can be found in the report on
83 voting indicated in the above table.
84 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
85 A list of all the parts in the IEC 61300 series, published under the general title, Fibre optic
86 interconnecting devices and passive components – Basic test and measurement procedures
87 can be found on the IEC website.
88 The committee has decided that the contents of this publication will remain unchanged until the
89 stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
90 the specific publication. At this date, the publication will be
91 • reconfirmed,
92 • withdrawn,
93 • replaced by a revised edition, or
94 • amended.
