Optical fibre cables - Part 1-201: Generic specification - Basic optical cable test procedures - Environmental test methods - Temperature cycling, method F1
IEC 60794-1-201: 2024 defines test procedures to be used in establishing uniform requirements for the environmental performance of: - optical fibre cables for use with telecommunication equipment and devices employing similar techniques; and - cables having a combination of both optical fibres and electrical conductors. Throughout this document, the wording "optical cable" can also include optical fibre units, microduct fibre units, etc. This document defines a test standard to determine the ability of a cable to withstand the effects of temperature cycling by observing changes in attenuation. See IEC 60794-1-2 for a reference guide to test methods of all types and for general requirements and definitions. This document partially replaces IEC 60794-1-22:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60794-1-22:2017: a) all references to the temperature sensing device have been removed and replaced with a note "for further study"; b) the conditioning procedure has been separated into Procedure 1 and Procedure 2 to avoid confusion; c) the ambient temperature test condition has been defined as per IEC 60794-1-2; d) the minimum soak time has been decreased for sample mass >16 kg in Table 1.

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 60794-1-201 has been prepared by subcommittee 86A: Fibres and
68 cables, of IEC technical committee 86: Fibre optics.
69 This first edition of IEC 60794-1-201 cancels and replaces Method F1 of the second edition of
70 IEC 60794-1-22: 2017. It constitutes a technical revision.
71 This edition includes the following significant technical changes with respect to the previous
72 edition:
73 a) remove all references to the temperature sensing device and replace with note “for further
74 study”;
75 b) separate the conditioning procedure into Procedure 1 and Procedure 2 to avoid confusion;
76 c) define the ambient temperature test condition as per IEC 60794-1-2;
77 d) decrease the minimum soak time for sample mass larger than 16 kg in table 1.
78 The text of this International Standard is based on the following documents:

134 4.1 Object
135 This measuring method applies to optical fibre cables, which are tested by temperature cycling
136 in order to determine the stability behaviour of the attenuation of cables submitted to

137 temperature changes. This method can also be used for evaluation of buffer tubes or other
138 elements independent of a cable construction, as defined by a detail specification.
139 Changes in the attenuation of optical fibre cables, which can occur with changing temperature,
140 are generally the result of buckling or tensioning of the fibres resulting from differences between
141 their thermal expansion coefficient and the coefficients of the cable strength and sheath
142 members. Test conditions for temperature-dependent measurements shall simulate the worst
143 conditions.
144 This test can be used either for monitoring cable behaviour in the temperature range, which can
145 occur during storage, transportation and usage, or to check, in a selected temperature range
