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
63 Publications.
64 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
65 indispensable for the correct application of this publication.
66 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
67 rights. IEC shall not be held responsible for identifying any or all such patent rights.
68 IEC 60794-1-207 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical
69 committee 86: Fibre optics. It is an International Standard.
70 This first edition of IEC 60794-1-207 cancels and replaces method F7 of the second edition of
71 IEC 60794-1-22 published in 2017.
72 This edition includes the following significant technical changes with respect to the previous
73 edition:
74 a) the environmental test contained in IEC 60794-1-22: 2017 will now be individually numbered
75 in the IEC 60794-1-2xx series. Each test method is now considered to be an individual
76 document rather than part of a multi-test method compendium. Full cross-reference details
77 are given in IEC 60794-1-2;
78 b) detailed content of sample, apparatus, procedure, requirements and details to be specified
79 of the methods is added.

86 accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
87 at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
88 described in greater detail at www.iec.ch/publications.
89 A list of all parts in the IEC 60794 series, published under the general title Optical fibre cables,
90 can be found on the IEC website.
91 The committee has decided that the contents of this document will remain unchanged until the
92 stability date indicated on the IEC website under webstore.iec.ch in the data related to the
93 specific document. At this date, the document will be
94 • reconfirmed,

99 OPTICAL FIBRE CABLES –
101 Part 1-207: Generic specification – Basic optical cable test procedures –
102 Environmental test methods – Nuclear radiation, Method F7
106 1 Scope
107 This part of IEC 60794 describes test procedures to be used in establishing uniform
108 requirements for optical fibre cables for the environmental property- nuclear radiation.
109 This document applies to optical fibre cables for use with telecommunication equipment and
110 devices employing similar techniques, and to cables having a combination of both optical fibres
111 and electrical conductors.
112 Method F7A evaluates performance degradation of optical fibre cable in environmental
113 background radiation; Method F7B evaluates performance degradation of optical fibre cable in
114 adverse nuclear environments.
115 NOTE Throughout the document, the wording "optical cable" can also include optical fibre units, microduct fibre units,
116 etc.
