Optical fibres - Part 1-33: Measurement methods and test procedures - Stress corrosion susceptibility
Describes methods for the determination of stress corrosion susceptibility parameters of optical fibres. Dynamic fatigue and static fatigue tests are used to determine stress corrosion susceptiblity parameters, dynamic n-value and static n-value. Five test methods are described: Dynamic and static n-value by axial tension, dynamic and static n-value by two-point bending, and static n-value by uniform bending. These tests provide values of the stress corrosion parameter, n, used for reliablilty calculations in EN 62048.

Fibres optiques - Partie 1-33: Méthodes de mesure et procédures d'essai - Résistance à la corrosion sous contrainte
Décrit des méthodes d'essai pour la détermination de la résistance à la corrosion sous contrainte des fibres optiques. Des essais de fatigue dynamique et de fatigue statique sont utilisés pour déterminer les paramètres de résistance à la corrosion sous contrainte, la valeur n de fatigue dynamique et la valeur n de fatigue statique. Cinq méthodes sont décrites: Valeur n de la fatigue dynamique et de fatigue statique par tension axiale, valeur n de la fatigue dynamique et de fatigue statique par flexion en deux points, et valeur n de fatigue statique par courbure uniforme. Ces essais fournissent les valeurs du paramètre de corrosion sous contrainte, n, utilisées dans les calculs de fiabilité de la EN 62048.

60793-1-33 © IEC:2001– 5 –INTERNATIONAL ELECTROTECHNICAL COMMISSION____________OPTICAL FIBRES –Part 1-33: Measurement methods and test procedures –Stress corrosion susceptibilityFOREWORD1)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.4)
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.5)
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 60793-1-33 has been prepared by subcommittee 86A: Fibres andcables, of IEC technical committee 86: Fibre optics.This standard, together with the other standards in the IEC 60793-1-3X series, cancels andreplaces the second edition of IEC 60793-1-3, of which it constitutes a technical revision.The text of this standard is based on the following documents:FDISReport on voting86A/688/FDIS86A/727/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 2.Annexes A, B, C, D, E form an integral part of this standard.Annexes F, G, H are for information only.
