44 FOREWORD
45 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
46 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
47 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
48 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
49 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
50 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
51 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
52 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
53 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
54 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
55 consensus of opinion on the relevant subjects since each technical committee has representation from all
56 interested IEC National Committees.
57 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
58 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
59 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
60 misinterpretation by any end user.
61 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
62 transparently to the maximum extent possible in their national and regional publications. Any divergence between
63 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
64 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
65 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
66 services carried out by independent certification bodies.
67 6) All users should ensure that they have the latest edition of this publication.
68 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
69 members of its technical committees and IEC National Committees for any personal injury, property damage or
70 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
71 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
72 Publications.
73 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
74 indispensable for the correct application of this publication.
75 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
76 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
77 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
78 may be required to implement this document. However, implementers are cautioned that this may not represent
79 the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
80 shall not be held responsible for identifying any or all such patent rights.
81 IEC 60794-1-205 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical
82 committee 86: Fibre optics. It is an International Standard.
83 This document partially replaces IEC 60794-1-22:2017. This edition constitutes a technical
84 revision.
85 This edition includes the following significant technical changes with respect to IEC 60794-1-
86 22:2017:
87 a) Revision of the contents of 4.6 Details to be specified and 4.7 Details to be reported in
88 comparison to IEC 60794-1-22: 2017, 5.6 and 5.7.
