Communication cables - Part 2-25: Common design rules and construction - Polypropylene insulation compounds

This European Standard gives specific requirements for PP compounds to be used for multi-element metallic data cables for indoor application. Type 1 is typically a copolymer with better low temperature properties. Type 2 is typically a homopolymer with superior hardness giving better crush resistance. Using compound and type test data as outlined in this standard, the compound supplier will have sufficient data to demonstrate compliance and warrant that the material is suitable for the specified application.

Komunikacijski kabli - 2-25. del: Skupna pravila načrtovanja in konstrukcija - Polipropilenske izolacijske zmesi

Ta evropski standard določa posebne zahteve za zmesi PP, ki se uporabljajo za večelementne kovinske podatkovne kable za notranjo uporabo. Tip 1 je običajno kopolimer z boljšimi lastnostmi pri nizkih temperaturah. Tip 2 je običajno homopolimer z boljšo trdoto, kar mu zagotavlja boljšo odpornost proti drobljenju. Z uporabo podatkov o zmesi in tipskem preskušanju, kot je opisano v tem standardu, bo imel dobavitelj zmesi dovolj podatkov, da dokaže skladnost in jamči, da je material ustrezen za opredeljeno uporabo.

Overview

SIST EN 50290-2-25:2014 is a European Standard developed by the CLC (European Committee for Electrotechnical Standardization) that specifies common design rules and construction requirements for polypropylene (PP) insulation compounds used in multi-element metallic data communication cables for indoor applications. This standard focuses on ensuring the suitability and compliance of PP compounds with physical, dielectric, mechanical, and combustion properties that contribute to cable performance and safety.

This standard supersedes the 2002 version and introduces updated compound test requirements and electrical insulation properties. It supports manufacturers, compound suppliers, and cable producers in meeting stringent quality standards for indoor communication cables.

Key Topics

• Scope and Application
  EN 50290-2-25 covers polypropylene compounds intended for indoor multi-element metallic data cables. Two primary types are defined:

  • Type 1 (Copolymer): Known for enhanced low-temperature flexibility.
  • Type 2 (Homopolymer): Offers superior hardness and crush resistance.

• Compound Test Requirements
  Suppliers must provide detailed test data for granules or molded plaques of insulation compounds. Tests evaluate:

  • Density and melt flow index
  • Shore D hardness and Charpy impact strength at low temperatures
  • Tensile strength and elongation
  • Oxidative induction time (thermal stability)
  • Dielectric properties (dielectric constant and dissipation factor)
  • Combustion properties including smoke opacity, corrosivity, acidity, and toxicity

• Cable Test Requirements
  Cables using compounds that comply with this standard should undergo tests for mechanical robustness, thermal aging, bending resistance at low temperatures, shrinkage, and adhesion strip force. Test methods include EN and IEC standards aligned with electrical insulation evaluation.

• Health, Safety & Environmental Compliance
  Compliance with health, safety, and environmental regulations outlined in EN 50290-2-20 is mandatory. Any deviations must be reported by the compound supplier.

Applications

SIST EN 50290-2-25:2014 is highly relevant for manufacturers and suppliers involved in the production of indoor communication cables, specifically:

• Data Transmission Cables: Multi-element metallic cables used in LAN, WAN, and other data networking systems inside buildings.
• Telecommunication Cables: Suitable for cables requiring dependable insulation with good electrical and mechanical characteristics.
• Control and Signal Cables: Indoor cables used in industrial, commercial, and residential settings for control and signaling applications.
• Low Temperature Environments: Enhanced polymer types (Type 1) provide flexibility and performance under cold conditions.
• Applications Requiring Durability: Type 2 compounds ensure crush resistance and mechanical integrity where physical stresses are common.

Related Standards

EN 50290-2-25 forms part of the broader EN 50290 series addressing communication cables and their material specifications. Key related standards include:

• EN 50290-2-20 – Common design rules and construction for communication cables (General).
• EN 50288 (all parts) – Specification for multi-element metallic cables used in analog and digital communication.
• EN 50290-2-21 & EN 50290-2-22 – PVC insulation and sheathing compounds.
• EN 50290-2-23 & EN 50290-2-24 – Polyethylene insulation and sheathing compounds.
• EN 60811 series – Test methods for non-metallic materials in electric and optical fiber cables.
• EN ISO 179-1 and EN ISO 527 – Plastics impact resistance and tensile property testing.
• EN 50267-2-2 – Testing gases evolved during combustion of cable materials to assess corrosivity.

Compliance with these interlinked standards ensures safety, reliability, and uniformity across electrical communication cable manufacturing in Europe.
