IEC 61757-1-1:20 20作为IEC 61757-1-1:20 20 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 61757-1-1:20 20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。IEC 61757中定义了光纤传感器的通用规范。本文件基于使用FBG作为敏感元件，规定了用于应变测量的光纤传感器最重要的特征和特性，并定义了其确定程序。此外，它规定了相应测量仪器的基本性能参数和特性，以从FBG读取光信号。本文件涉及一系列频率中静态和动态应变值的测量。空白详细质量标准见附录B。这第二版取消并取代了2016年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下技术变更:-更新引用的标准；-澄清定义和测试规范。

IEC 61757-1-1:2020 is available as IEC 61757-1-1:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the 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.
