Annotation of standard text IEC 61757-1-2-ed.1.0 :

IEC 61757-1-2: 2023 defines detailed specifications for distributed strain measurements with a fibre optic sensor, also known as "fibre optic distributed strain sensing". It is applicable to distributed strain sensing systems (DSS) based on spontaneous or stimulated Brillouin scattering in the optical fibre sensor (strain sensitive element), that is, to sensors capable of measuring absolute strain. This document specifies the most important DSS performance parameters and defines the procedures for their determination. IEC 61757-1-2: 2023 definit des specifications particulieres pour les mesures de deformation reparties avec un capteur fibronique, egalement appelees "detection de deformation repartie fibronique". Elle s’applique aux systemes fibroniques repartis de detection de deformation (DSS) bases sur la diffusion de Brillouin spontanee ou stimulee dans le capteur a fibres optiques (element sensible a la deformation), c’est-a-dire aux capteurs capables de mesurer la deformation absolue. Le present document specifie les parametres de performance DSS les plus importants et definit les procedures pour leur determination.
