General Information
Relations
Overview
IEC 61300-2-22:2024 specifies a standardized change of temperature test procedure for verifying that fibre optic interconnecting devices and passive components can withstand single or repeated temperature changes. Published as part of the IEC 61300 series, this 2024 edition (Edition 3.0) expands the scope to explicitly include passive components, patch cords, splices, fibre management systems and protective housings, and aligns severity categories with IEC 61753‑1.
Key topics and technical requirements
- Test basis: Procedure is conducted in accordance with IEC 60068‑2‑14 (Test Nb) - change of temperature with a specified rate of change.
- Temperature profile: Start from standard atmospheric conditions, ramp to the low extreme, dwell, ramp to the high extreme, dwell, then repeat cycles. Ramp rate specified as (1 ± 0.2) °C/min.
- Dwell times: Each extreme is maintained for a minimum dwell period (minimum 1 hour as stated for typical tests).
- Preconditioning: Maintain the Device Under Test (DUT) under standard atmospheric conditions per IEC 61300‑1 for at least 2 h (or ≥4 h for large devices such as protective housings).
- Test setup: Use a suitable environmental test chamber compliant with IEC 60068‑2‑14. Include 1.5 m of cable in the chamber for each monitored port unless otherwise specified.
- Measurements and monitoring: Optical and physical examinations (e.g., attenuation, return loss, visual inspection) are performed per relevant IEC 61300‑3 parts. At minimum, measurements are taken at the end of each dwell at each temperature extreme and a maximum measurement period of 10 minutes is recommended between optical measurements during performance testing.
- Apparatus and instruments: Use environmental chambers and optical test equipment referenced in IEC 60529 and IEC 61300‑3‑x series, consistent with IEC 61753 performance or IEC 62005 reliability requirements.
- Severity and reporting: Severity categories, cycle counts and extreme durations have been updated to align with IEC 61753‑1. Test details and results must be specified and reported per the standard.
Applications and who uses it
- Manufacturers of optical connectors, patch cords, splices, modules and fibre management systems use this standard to validate product performance under thermal cycling.
- Test laboratories and qualification teams apply IEC 61300‑2‑22 for environmental qualification and reliability testing.
- System integrators and specifiers reference this test when defining environmental requirements for telecom, datacom, industrial and outdoor fibre deployments.
- Certification bodies and OEMs use the procedure to demonstrate compliance with industry performance classes.

clarified or removed. The ambiguous statement “relevant specification” is removed in
Clause 6.
8 The duration of preconditioning for devices such as protective housings is longer due to
their size.

10 Sample configurations is defined in IEC 61300-1 to avoid inconsistency amongst other test
documents.

1 h for connectors, field mountable connectors, passive components, splices, and fibre
management systems. It is 4 h for wall outlets, boxes, optical distribution frame modules,
and closures.

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
