Overview

EN IEC 61300-2-5:2022/A1:2025 is the CENELEC amendment to IEC 61300‑2‑5 that defines the torsion (twist) test procedures for fibre optic interconnecting devices and passive components. It is part of the IEC 61300 series on basic test and measurement procedures for optical-fibre components and was approved as a European Standard in 2025. This amendment (A1) updates preconditioning and severity parameters used when performing torsion tests on connectors, splices, passive components, fibre-management systems and protective housings.

Key topics and requirements

• Test focus: Torsion (mechanical twisting) on fibre optic interconnecting devices and passive components.
• Preconditioning updated:
  • Precondition each device under test (DUT) for at least 2 hours for connectors, splices, passive components and fibre management systems at the standard atmospheric condition defined in IEC 61300‑1.
  • For protective housings including closures, precondition for at least 4 hours.
  • If the torsion test is carried out at non‑standard ambient temperatures, allow at least 4 hours of conditioning for components and protective housings.
• Severity (number of cycles) updated: In Table 1, the number of torsion cycles for connectors and field‑mountable connectors with 250 µm primary coated fibre or 900 µm buffered fibre is changed from 10 to 25 cycles.
• Normative link: References and conditioning conditions are tied to IEC 61300‑1 (standard atmospheric conditions and general test conditions).

Applications and who uses this standard

• Manufacturers of fibre optic connectors, splices, passive components, closures and fibre management systems use this standard to design and validate mechanical robustness to torsion.
• Test laboratories and quality assurance teams apply these procedures to verify product compliance and durability.
• Procurement, certification bodies and system integrators rely on the standard to specify and assess component mechanical performance in telecom, data centre and field-installation environments.
• Useful for R&D and product qualification where twist resistance affects optical performance and long‑term reliability.

Related standards

• IEC 61300‑1 (basic test and measurement procedures - general conditions and definitions) - referenced for standard atmospheric condition and conditioning procedures.
• Other parts of the IEC 61300 series (basic test and measurement procedures) covering different mechanical, environmental and optical tests.

Keywords: IEC 61300‑2‑5, EN IEC 61300‑2‑5:2022/A1:2025, torsion test, fibre optic connectors, passive components, preconditioning, test cycles, fibre management systems, protective housings.
