Overview

EN 50104:2019/A1:2023 - issued by CLC/CENELEC - defines performance requirements and test methods for electrical equipment used to detect and measure oxygen in gas mixtures (indicating up to 25 % v/v). The amendment A1 updates normative references, general requirements and specific test procedures for portable, transportable and fixed oxygen detection and measurement equipment. It supports conformity with EU regulatory requirements and was prepared by CLC/TC 31 for implementation by national bodies.

Key topics and technical requirements

  • Scope: Measurement of oxygen concentration in gases (≤ 25 % v/v) for portable, transportable and fixed devices.
  • Normative references updated: Integrates related standards such as EN 50270:2015 (EMC), EN 50271:2018 (software/digital technologies), EN 60068-2-6:2008 (vibration), and EN 60079-29-2:2015 (selection/installation for explosive atmospheres).
  • Equipment using software/digital technologies: Devices with software must meet the design, verification and functional requirements of EN 50271:2018 (Clause 4 & 5).
  • Electromagnetic compatibility (EMC): EMC testing is aligned with EN 50270:2015 (Clauses 4–6) and devices must satisfy performance criteria specified in that standard.
  • Vibration testing: Vibration tests follow EN 60068-2-6:2008 procedures, with temperature/pressure/humidity limited only to avoid sensor damage (ambient condition requirements may be relaxed for this test).
  • Installation and user guidance: The amendment recommends users consult EN 60079-29-2:2015 and other codes of practice for selection, installation and maintenance guidance.

Applications and who uses this standard

  • Manufacturers of oxygen detectors and analysers (portable, transportable, fixed) use EN 50104:2019/A1:2023 to design and validate product performance and compliance.
  • Test laboratories apply the specified test methods for type testing, EMC evaluation and software verification.
  • Safety engineers and maintenance personnel rely on the standard for performance expectations and installation recommendations in industrial, medical, laboratory and hazardous-area settings.
  • Procurement and regulatory bodies use the standard to define acceptance criteria and to ensure devices meet EU essential requirements.

Related standards
