Standards Development
The proposed International Standard defines the terminology, structure, and measurement methods of
optical displacement sensors based on fibre Bragg gratings (FBGs) as the sensitive element. It also
specifies the most important features and characteristics of these fibre optic displacement sensors and
defines procedures for their determination.
If approved, this standard will be part of the IEC 61757 series, which is dedicated to fibre optic
sensors. The individual parts of the IEC 61757 series are numbered as IEC 61757-M-T, where M
denotes the measure and T the technology of the fibre optic sensor. The sub-series IEC 617575-6-T is
concerned with displacement measurements.
Specific aims and reasons for this standardization activity
The proposed standard provides manufacturers and applicants of displacement sensing systems with technical specifications and related measurement procedures, which will improve the confidence in this new technology and accelerate its acceptance in the market, especially for safety relevant applications. The standard defines harmonized and technically accurate specifications as well as corresponding test methods to determine the performances and the reliability of fibre optic displacement sensors.
Main interest and timeliness of the activity
Fibre optic displacement sensors are already used in various fields of application, but still on a relatively small scale. Deployments of these sensors include structural health monitoring in civil engineering (piles, walls, dams, bridges and tunnels, for example), geotechnology (ground movement, landslides), oil and gas (pipeline deformation, fatigue monitoring) and power cables (deformation, installation).
Broader acceptance of this sensor technology is hindered by the lack of internationally harmonized standards in the field of fibre optic displacement sensors.
Feasibility of the activity
There are no factors (e.g. patents, principal regulations from regulatory bodies) known, which could hinder the successful establishment or general application of the proposed standard. Moreover, WG 2 of SC 86C has 69 expert members from 17 countries, representing a wealth of expertise and knowledge in the field of fibre optic sensing.
Benefits
Equipment vendors and users both will benefit from this standard, which provides well-defined guidelines to manufacturers for specifying measurement performance and reliability of their products and, in addition, helps users to select, install and operate fibre optic displacement sensors based on widely recognized procedures.
