标准摘要
[中文适用范围]： 本部分IEC 61757定义了使用一个或多个光纤布拉格光栅(FBG)作为应变测量敏感元件的光纤传感器的详细规范。光纤传感器的通用规范在IEC 61757-1:2012中定义。 本文件规定了基于FBG作为敏感元件的光纤应变传感器的最重要特性和特征，并定义了其确定程序。此外，它还规定了读取FBG光学信号的相应测量仪器的基本性能参数和特性。本文件涉及在一定频率范围内的静态和动态应变值的测量。 空白详细规范见附录B [外文原描述]： IEC 61757-1-1:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. 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.
