Optical fibres - Part 1-54: Measurement methods and test procedures - Gamma irradiation

Provides a method for measuring the steady state response of optical fibres and optical cables exposed to gamma radiation. It can be used to determine the level of radiation-induced attenuation produced in single-mode or multimode optical fibres, in either cabled or uncabled form, due to exposure to gamma radiation. This procedure focuses on two regimes of interest: the low dose rate regime suitable for estimating the effect of environmental background radiation, and the high dose rate regime suitable for estimating the effect of adverse nuclear environments.

Fibres optiques - Partie 1-54: Méthodes de mesure et procédures d'essai - Irradiation gamma

Présente une méthode de mesure de la réponse en régime permanent des fibres optiques et câbles optiques exposés au rayonnement gamma. Elle peut être utilisée pour déterminer le niveau d'affaiblissement induit par le rayonnement produit dans les fibres optiques unimodales et multimodales, sous forme câblée ou non câblée, du fait d'une exposition au rayonnement gamma.La présente procédure d'essai se focalise sur deux régimes intéressants: le régime de débit de dose faible adapté pour l'estimation de l'effet du rayonnement de l'environnement général, et le régime de débit de dose élevé pour l'estimation de l'effet d'environnements nucléaires hostiles.

60793-1-54  IEC:2003– 5 –INTERNATIONAL ELECTROTECHNICAL COMMISSION____________OPTICAL FIBRES –Part 1-54: Measurement methods and test procedures –Gamma irradiationFOREWORD1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the InternationalOrganization for Standardization (ISO) in accordance with conditions determined by agreement between thetwo organizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.4)
In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)
The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)
Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 60793-1-54 has been prepared by subcommittee 86A: Fibres andcables, of IEC technical committee 86: Fibre optics.The text of this standard is based on the following documents:FDISReport on voting86A/852/FDIS86A/866/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives, Part 2IEC 60793-1-5X consists of the following parts, under the general title Optical fibres:Part 1-50: Measurement methods and test procedures – Damp heat (steady state)Part 1-51: Measurement methods and test procedures – Dry heatPart 1-52: Measurement methods and test procedures – Change of temperaturePart 1-53: Measurement methods and test procedures – Water immersionPart 1-54: Measurement methods and test procedures – Gamma irradiationSIST EN 60793-1-54:2004
