9 AMENDMENT 1
11 FOREWORD
12 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
13 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
14 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
15 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
16 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
17 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
18 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
19 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
20 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
21 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
22 consensus of opinion on the relevant subjects since each technical committee has representation from all
23 interested IEC National Committees.
24 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
25 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
26 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
27 misinterpretation by any end user.
28 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
29 transparently to the maximum extent possible in their national and regional publications. Any divergence between
30 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
31 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
32 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
33 services carried out by independent certification bodies.
34 6) All users should ensure that they have the latest edition of this publication.
35 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
36 members of its technical committees and IEC National Committees for any personal injury, property damage or
37 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
38 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
39 Publications.
40 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
41 indispensable for the correct application of this publication.
42 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
43 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
44 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
45 may be required to implement this document. However, implementers are cautioned that this may not represent
46 the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
47 shall not be held responsible for identifying any or all such patent rights.
48 Amendment 1 to IEC 61291-5-2:2017 has been prepared by subcommittee 86C: Fibre optic
49 systems and active devices, of IEC technical committee 86: Fibre optics.
50 The text of this Amendment is based on the following documents:
