Overview
EN IEC 60794-1-125:2026 is an international standard published by CLC and IEC that specifies the ripcord functional test method (Method E25) for optical fibre cables. This standard focuses on evaluating the functionality of cable ripcords - the embedded cords designed to facilitate the safe and efficient opening of optical cable sheaths. As the first edition, EN IEC 60794-1-125:2026 replaces the previous Method E25 from IEC 60794-1-21:2017, reflecting an updated editorial structure with no technical changes while aligning with the ongoing series of optical cable test procedures.
Key Topics
- Ripcord Functional Test Scope:
- Establishes procedures to test ripcords integrated in optical fibre cables.
- Ensures ripcord can rip through the cable sheath (jacket and armour, if present) without breaking.
- Test Methodology:
- Specifies sample preparation and minimum lengths for reliable testing.
- Details the use of a climatic chamber to simulate real-world installation temperatures (minimum/maximum), as referenced in IEC TR 62691.
- Outlines the test steps, including preconditioning, pulling the ripcord through 1 meter of sheath, and evaluation criteria.
- Requirements and Reporting:
- The ripcord must fully open the sheath over a specified length without failing.
- If initial tests fail, additional specimens must be tested for statistical reliability.
- Reports must document sample construction, ripcord material, temperatures, and test results.
Applications
The guidelines in EN IEC 60794-1-125:2026 are critical for:
- Optical fibre cable manufacturers: Provides a standardized process for assessing the performance and reliability of ripcords during product development and quality control.
- Network installers and operators: Ensures that optical cables can be safely and efficiently accessed in the field, minimizing the risk of damage to fibre elements during sheath removal.
- Certification bodies and testing laboratories: Offers a repeatable, internationally recognized procedure to validate cable designs prior to deployment in telecommunication networks.
- Procurement and specification: Supports purchasing decisions by standardizing ripcord performance expectations for cables deployed in a range of environmental conditions.
Testing ripcord functionality as described is vital for reliable cable access in construction, maintenance, and repair scenarios where efficient and controlled sheath removal is necessary for splicing or reconfiguration.
