31 FOREWORD
32 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
33 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
34 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
35 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
36 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
37 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
38 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
39 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
40 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
41 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
42 consensus of opinion on the relevant subjects since each technical committee has representation from all
43 interested IEC National Committees.
44 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
45 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
46 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
47 misinterpretation by any end user.
48 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
49 transparently to the maximum extent possible in their national and regional publications. Any divergence between
50 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
51 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
52 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
53 services carried out by independent certification bodies.
54 6) All users should ensure that they have the latest edition of this publication.
55 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
56 members of its technical committees and IEC National Committees for any personal injury, property damage or
57 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
58 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
59 Publications.
60 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
61 indispensable for the correct application of this publication.
62 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
63 rights. IEC shall not be held responsible for identifying any or all such patent rights.
64 IEC 60794-1-119 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical
65 committee 86: Fibre optics. It is an international Standard.
66 This first edition of IEC 60794-1-119 cancels and replaces test method E19 of the first edition
67 of IEC 60794-1-21 published in 2015.
68 This edition includes a few editorial changes to improve the content and the following significant
69 technical changes with respect to the previous edition:
70 a) the mechanical tests contained in IEC 60794-1-21: 2020 will now be individually
71 numbered in the IEC 60794-1-1xx series. Each test method is now considered to be an
72 individual document rather than part of a multi-test method compendium. Full cross-
73 reference details are given in IEC 60794-1-2.
74 b) A system to maintain a constant cable tension during the duration of the test as well as
75 means to measure the free loop antinode amplitude have been added to the Apparatus.

76 c) Cable load is fixed to 25 % of the rated tensile strength for OPGW/OPPC, or to the
77 maximum installation tension (MIT) for ADSS cable.
78 d) The target free loop peak-to-peak antinode amplitude is now defined in the procedure.
79 The quality of the aeolian vibration motion is done through the average antinode peak
80 velocity.
81 e) Fatigue damage and ovality changes of the optical core are included in the
82 Requirements clause.
84 The text of this standard is based on the following documents:

108 This part of IEC 60794 applies to aerial optical fibre cables like ADSS, OPGW and OPPC that
109 might be exposed to aeolian vibrations.
110 The object of this standard is to define test procedures to be used in establishing uniform
111 requirements for mechanical performance – aeolian vibration.
112 See IEC 60794-1-2 for general requirements and definitions and for a complete reference guide

130 4 Method E19: Aeolian vibration
131 4.1 Object
132 The purpose of the test is to expose aerial optical cables and their support hardware to dynamic
133 stresses similar to those imposed by laminar wind-flow-induced vibrations in overhead lines.
134 The method is intended to assess the fatigue performance of the aerial cable and the optical
135 performance of the optical fibres under such conditions.
