The purpose of this standard is to determine the suitability of optical fibre sub-category A1a to A1d multimode fibres and class B and C single-mode fibres to withstand the environmental condition of high temperature (dry heat) which may occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of effects of high temperature over a given period. This procedure is conducted in accordance with IEC 60068-2-2, Test Bd. This second edition cancels and replaces the first edition, published in 2001, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - harmonizing the content with sectional specifications of relevant fibre types; - extending the applicability of the document to class C single-mode fibres.

IEC 60793-1-51:2014 présente une méthode pratique pour l'évaluation des performances des fibres dans un environnement défini. L'objet de la présente norme est de déterminer l'aptitude des fibres optiques multimodales de sous-catégories A1a à A1d et des fibres optiques unimodales de classes B et C à résister aux conditions d'environnement présentant une température élevée (chaleur sèche), susceptibles de survenir en utilisation réelle, pendant le stockage et/ou le transport. L'essai est essentiellement destiné à permettre l'observation des effets d'une température élevée pendant une période donnée. Cette procédure est appliquée conformément à l'IEC 60068-2-2, Essai Bd. Cette deuxième édition annule et remplace la première édition, publiée en 2001, dont elle constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - l'harmonisation du contenu avec les spécifications intermédiaires concernant les types de fibres correspondants; - l'extension de l'applicabilité du document aux fibres unimodales de classe C. Mots clés: optiques multimodales de sous-catégories A1a à A1d, fibres optiques unimodales de classes B et C, température élevée (chaleur sèche)

EN IEC 60793-1-51 zagotavlja praktično metodo za ocenjevanje delovanja vlaken v nadzorovanem okolju. Namen tega standarda je določiti ustreznost podkategorij večrodovnih optičnih vlaken A1a do A1d in enorodnih optičnih vlaken razredov B in C pri prenašanju okoljskih pogojev, kot je visoka temperatura (suha toplota), ki se lahko pojavi pri dejanski uporabi, shranjevanju in/ali prevozu. Preskus je zlasti namenjen omogočanju opazovanja učinkov visoke temperature v določenem časovnem obdobju. Ta postopek se izvaja v skladu s preskusom Bd iz IEC 60068- 2-2.

Overview
EN 60793-1-51:2014 (IEC 60793-1-51:2014) defines a measurement and test procedure for evaluating optical fibre performance under sustained dry heat. The standard specifies a practical method to determine whether optical fibre sub-category A1a to A1d multimode fibres and class B and C single-mode fibres can withstand high temperature (dry heat) conditions that may occur during use, storage or transport. This edition harmonizes content with sectional fibre specifications and extends applicability to class C single-mode fibres.
Key topics and technical requirements
- Test environment: Conducted in an environmental chamber per IEC 60068-2-2, Test Bd (dry heat, steady state). Chamber must avoid direct radiant heat and may use forced air circulation to ensure homogeneity.
- Temperature and exposure:+85 °C for 30 days (humidity uncontrolled; recommended ≥ 50 % RH at test start).
- Specimen length and preparation:
- Minimum 1 000 m for A1a–A1d multimode fibres.
- Minimum 2 000 m for class B and C single-mode fibres.
- Specimens are loosely coiled (horizontal or vertical) with minimum bend diameter 150 mm; dusting (e.g., talcum) is recommended so coils move freely. A control length is removed before the test for baseline mechanical measurements.
- Temperature change rate: Rate of change must not exceed 1 °C/min, averaged over a maximum period of 5 minutes, during ramp-up and cool-down.
- Optical measurements: Attenuation shall be measured at wavelengths specified in the relevant product specification using IEC 60793-1-40 methods (insertion loss - Annex B, or backscattering - Annex C) before, during (once stabilized) and after conditioning. Record attenuation changes; other optical tests may be specified by product details.
- Preconditioning and measurements during conditioning: Per detail specification when required. The standard defines sampling, apparatus and test procedure; pass/fail criteria are given in the applicable product or sectional specification.
Applications and who uses it
- Quality assurance and type-approval testing by optical fibre manufacturers and independent test laboratories.
- Product development and reliability assessment for telecommunications, data center interconnects, and other fibre-optic systems subject to elevated temperature during installation, storage or transport.
- Procurement and compliance verification for spec writers, purchasers and certification bodies who need objective evidence of fibre performance under high-temperature (dry heat) conditions.
Related standards

- IEC 60793-2-50 - Sectional specification for class B single-mode fibres
- IEC 60793-2-60 - Sectional specification for class C single-mode fibres
This standard is essential when evaluating the resilience of optical fibre sub-category A1a–A1d multimode fibres and class B and C single-mode fibres to prolonged high temperature (dry heat) exposure and for ensuring measurable, repeatable attenuation and mechanical performance under those conditions.

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 determin
