FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 60794-1-403 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical
committee 86: Fibre optics. It is an International Standard.
This document partially cancels and replaces IEC 60794-1-24:2014.
The text of this International Standard is based on the following documents:

This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at /members_experts/refdocs. The main document types developed by IEC are
described in greater detail at /standardsdev/publications.
A list of all the parts in the IEC 60794 series, published under the general title Optical fibre
cables, can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
INTRODUCTION
This document contains method H3 of IEC 60794-1-24:2014, which will be withdrawn. The
system for optical fibre test methods have been restructured and renumbered. The electrical
tests contained in IEC 60794-1-24:2014 will now be individually numbered in the IEC 60794-1-
4xx series. Each test method is now considered to be an individual document rather than part
of a multi-test method compendium. Full cross-reference details of the methods are given in
IEC 60794-1-2.

OPTICAL FIBRE CABLES –
Part 1-403: Generic specification – Basic optical cable
test procedures – Electrical test methods – Electrical continuity
test of cable metallic elements, method H3
1 Scope
This part of IEC 60794 specifies a method of verifying that cable metallic elements are
electrically continuous throughout the cable. Electrical continuity is important for bonding and
grounding, toning for location, and other related system issues, and may represent a "goodness
of manufacture" criterion. Typically, the test is one of continuity and carries no resistance or
conductivity requirement. The metallic elements can be tested individually or can be tested as
a total group. Since this latter criterion is frequently the case, all elements are measured as a
group unless specified otherwise.
NOTE It is possible detail specifications allow such elements as strength members to be non-continuous throughout
the cable. This is a special case, and attention is directed to the detail specification.
