Overview

EN IEC 61300-2-5:2022 (IEC 61300-2-5:2022) specifies a standardized torsion test for fibre optic interconnecting devices and passive components. Published as the fourth edition and adopted by CLC/CENELEC, this standard determines the ability of a device’s cable attachment element to withstand torsional loads encountered during installation and normal service. The 2022 edition is a technical revision of the 2009 edition, adding terms and definitions, refining the test procedure and sequence, updating figures, and revising test severity based on component and operating conditions.

Key Topics

• Scope and purpose: Assess resistance of cable attachments to torsional stress that may occur in the field.
• Apparatus: Describes required test fixtures such as mounting fixtures for components/devices, clamps/mandrels, tensile-load equipment and optical/mechanical measurement tools.
• Test procedure (Clause 6): Includes preparation and preconditioning of the device under test (DUT), mounting, initial optical measurements, clamping and application of tensile load, controlled twisting of the cable, monitoring of optical properties (attenuation, return loss, transient loss) and sealing (for closures), recovery, and final measurements and examinations.
• Monitoring: Active monitoring of changes in attenuation and return loss during torsion is specified to capture transient and permanent effects.
• Severity levels: Test severity is updated and recommended by component type and operating conditions (see Table 1 in the standard); severity selection is part of test specification and reporting.
• Test set-ups: Illustrations for component/device and protective-housing arrangements (Figure 1 and Figure 2) are provided for reproducible testing.

Applications

EN IEC 61300-2-5:2022 is used by:

• Manufacturers of fibre optic connectors, adapters, splice closures and passive components for design validation and production quality control.
• Test laboratories and QA teams performing type approval, incoming inspection and failure analysis.
• Procurement and compliance engineers specifying mechanical robustness requirements for installation-ready products.
• Field and installation engineers who need to understand expected mechanical limits under torsional stresses.
• Certification bodies assessing conformity to IEC/CENELEC test suites for optical interconnection devices.

Practical outcomes include improved product durability, reliable optical performance under mechanical stress (reduced attenuation/return-loss degradation), and verified sealing performance for closures subjected to twisting.

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 61300-2-5 has been prepared by subcommittee 86B: Fibre optic interconnecting devices
and passive components, of IEC technical committee 86: Fibre optics. It is an International
Standard.
This fourth edition cancels and replaces the third edition published in 2009. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) The terms and definitions clause was added;
b) the procedure description was modified;
c) new subsections are included in Clause 6 for a better sequence description;
d) Figure 1 was improved and Figure 2 was updated in text descriptions;
