Overview
EN 50290-2-26:2002 - Communication cables: Part 2-26 - defines specific requirements for halogen‑free flame retardant insulation compounds used in communication cables. Published by CENELEC/CLC, this Part is intended to be read in conjunction with EN 50290‑2‑20 and establishes mechanical, thermal, electrical and fire‑related performance criteria and test methods for insulation materials (both cross‑linked and thermoplastic grades).
Key topics and technical requirements
The standard specifies:
- Scope and normative references - integrates test methods from the EN 60811 series, IEC 60250, IEC 60754‑2, HD 405.3 and others for consistent verification of material properties.
- Material grades - separate provisions for cross‑linked and thermoplastic insulation compounds with defined maximum rated cable temperatures (typically 90 °C for cross‑linked, 70 °C for thermoplastic).
- Mechanical properties - delivery-state and post‑ageing tensile strength and elongation requirements (median minima and allowable variation), using EN 60811‑1‑1 and EN 60811‑1‑2.
- Thermal endurance and heat shock - ageing protocols (e.g. multi‑day oven ageing at specified temperatures) and heat‑shock/low‑temperature bending tests to demonstrate no cracking.
- Dimensional stability - shrinkage and pressure‑at‑high‑temperature acceptance criteria (EN 60811‑1‑3, EN 60811‑3‑1).
- Fire and toxicity indicators - guidance on oxygen index, smoke opacity and corrosivity; gases corrosivity referenced to IEC 60754‑2. Toxicity is noted as under consideration.
- Electrical properties - volume resistivity requirements (normative Annex A describes the measurement method and provides the formula), and typical dielectric constant/dissipation factor measurement guidance (IEC 60250) when required.
- Other tests - hot‑set, low temperature and hot‑set tests per EN 60811 series where applicable.
Practical applications and users
EN 50290-2-26:2002 is used by:
- Cable designers and manufacturers specifying halogen‑free flame retardant insulation for telecom, data and coaxial cables.
- Material suppliers qualifying polymer compounds for communication cable use.
- Test laboratories performing acceptance and type tests to EN/IEC methods.
- Procurement/specification authors and safety engineers who require documented fire‑performance, low smoke and low corrosivity characteristics for indoor and public network installations.
Benefits include improved fire safety (halogen‑free, reduced corrosive gases), clearer material selection criteria, and harmonised test methods for reliable cable performance.
Related standards
- EN 50290‑2‑20 (general rules for cable design and construction)
- EN 60811 series (insulating and sheathing materials - common test methods)
- IEC 60250 (permittivity and dissipation factor)
- IEC 60754‑2 (gases evolved during combustion - corrosivity)
