Full title and description

IEC 61757:2018 — Fibre optic sensors. Generic specification. This international standard provides a common framework, definitions, classification and generic requirements for optical fibres, components and sub‑assemblies intended for use in fibre optic sensing applications, to be used by vendors, designers, manufacturers and users across applications and industries.

Abstract

IEC 61757:2018 establishes terminology, classification schemes, interface and marking rules, safety considerations, ordering information and generic test and performance attributes applicable to the IEC 61757 family of standards. It is intended as the foundational (generic) specification that other sectional, family and detail specifications within the 61757 series reference and build upon.

Scope

Defines a generic specification applicable to fibre optic sensors and to the optical-fibre components and sub-assemblies used in sensing systems. The scope covers classification and designation, definitions and terms, transduction principles, spatial distribution and interface levels, marking/packaging/instructions, IEC type designation, safety aspects, ordering information and illustrative examples of sensor types and applications. The requirements apply across the IEC 61757 series and provide the framework for subsequent parts that address particular measured quantities or specific sensor families.

Key topics and requirements

• Terminology and definitions specific to fibre optic sensing (to harmonize communication between suppliers and users).
• Classification scheme for fibre optic sensors, components and sub‑assemblies (by measured quantity, transduction principle and interface level).
• Generic functional and performance attributes to be specified (sensitivity, range, resolution, response time, environmental limits).
• Transduction principles and mapping of common sensing mechanisms (intensity, phase, polarization, spectrum, FBGs, interferometric and other techniques).
• Requirements for marking, labelling, packaging, documentation and IEC type designation to support traceability and procurement.
• Safety considerations including personal safety and requirements for hazardous environments.
• Ordering information template and examples; illustrative annex with typical fibre‑optic sensor examples and use cases.

Typical use and users

Used by component suppliers, sensor system designers, equipment manufacturers, test labs and end users in industries that deploy optical fibre sensing (structural health monitoring, civil engineering, oil & gas, utilities, aerospace, transportation, industrial process monitoring, laboratory and R&D). It is intended to harmonize specifications between vendors and purchasers and to serve as the base reference for detail specifications addressing particular measurement quantities.

Related standards

IEC 61757:2018 supersedes older generic documents in the 61757 family (for example EN/IEC 61757‑1:2012 as the previous generic specification) and is intended to be used alongside other sectional and detail parts of IEC 61757 (e.g., parts specifying strain sensors based on FBGs and other quantity-specific detail specifications). The standard family also cross-references related standards for optical fibres and components (examples include EN/IEC publications in the 61753 family and relevant fibre and optical component specifications).

FAQ

Q: What is this standard?

A: IEC 61757:2018 is the international generic specification for fibre optic sensors — it provides the definitions, classification, generic requirements, and framework used across the IEC 61757 series.

Q: What does it cover?

A: It covers terminology, classification, interface levels, transduction principles, marking/packaging/instructions, safety aspects, ordering information and illustrative examples; essentially the foundational rules and templates that other 61757 parts use to specify sensors for particular measured quantities.

Q: Who typically uses it?

A: Component and sensor manufacturers, system designers and integrators, procurement specialists, certification and test labs, research institutions and end users deploying fibre optic sensing across civil, industrial and scientific applications.

Q: Is it current or superseded?

A: IEC 61757:2018 is the current generic specification (published 25 Jan 2018) and replaces the previous IEC/EN 61757‑1:2012 generic document; its stability/date of validity is listed in the IEC record.

Q: Is it part of a series?

A: Yes — IEC 61757 is a family of standards. Part 1 (the generic specification) is intended as the base; other parts, family and detail specifications of IEC 61757 address sensors for specific physical quantities and specific sensor types.

Q: What are the key keywords?

A: Fibre optic sensors, optical fibre components, FBG, transduction principles, sensor classification, interface levels, marking/packaging, generic specification.
