Annotation of standard text IEC 61757-1-1-ed.2.0 :
IEC 61757-1-1:2020 defines detail specifications for fibre optic sensors using one or more fibre Bragg gratings (FBG) as the sensitive element for strain measurements. Generic specifications for fibre optic sensors are defined in IEC 61757. This document specifies the most important features and characteristics of a fibre optic sensor for strain measurements, based on use of an FBG as the sensitive element, and defines the procedures for their determination. Furthermore, it specifies basic performance parameters and characteristics of the corresponding measuring instrument to read out the optical signal from the FBG. This document refers to the measurement of static and dynamic strain values in a range of frequencies. A blank detail specification is provided in Annex B. This second edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. This edition includes the following technical changes with respect to the previous edition: - update of cited standards; - clarification of definitions and test specifications. LIEC 61757-1-1:2020 definit des specifications particulieres pour des capteurs fibroniques utilisant un ou plusieurs reseaux de Bragg a fibres (FBG, fibre Bragg gratings) comme element de detection pour les mesures de deformation. Des specifications generiques pour les capteurs fibroniques sont definies dans lIEC 61757. Le present document specifie les caracteristiques les plus importantes dun capteur fibronique servant a mesurer des deformations en utilisant un FBG comme element de detection, et il definit les procedures permettant de determiner ces caracteristiques. Il specifie egalement les parametres et les caracteristiques des performances de base de lappareil utilise pour mesurer le signal optique provenant du FBG. Le present document porte sur la mesure des valeurs de deformations statiques et dynamiques sur une plage de frequences. Une specification particuliere-cadre est fournie a lAnnexe B. Cette deuxieme edition annule et remplace la premiere edition parue en 2016 dont elle constitue une revision technique. La presente edition inclut les modifications techniques suivantes par rapport a ledition precedente: - mise a jour des normes citees; - clarification des definitions et des specifications dessais.
