SIST EN 50441-1:2012

Cables for indoor residential telecommunication installations - Part 1: Unscreened cables - Grade 1

This European Standard specifies the constructional details and performances requirements for cables for indoor residential cabling systems characterized up to 100 MHz. Cables in this European Standard are based on the common design rules specified in EN 50290-2-1 and are specifically intended for supporting ICT and BCT applications (telephone, computer and TV services) as specified in EN 50173-4. The cables covered in this European Standard are intended to operate with voltages and currents normally encountered in communications systems. These cables are not intended to be used in conjunction with low impedance sources, for example, the electrical power supply of public utility mains. Cables covered in this European Standard may however be subjected to voltages of not more than 300 V a.c. or 450 V d.c. and comply with the requirements of the Low Voltage Directive. The maximum current rating per conductor is 3 A/mm? unless otherwise specified in the relevant detail specification.

Kabli za notranjo stanovanjsko telekomunikacijsko montažo - 1. del: Nezaslonjeni kabli - 1. stopnja

Ta evropski standard določa konstrukcijske podrobnosti in zahteve v zvezi z delovanjem za kable za notranje stanovanjske kabelske sisteme za zmogljivosti do 100 MHz. Kabli v tem evropskem standardu temeljijo na splošnih pravilih za načrtovanje iz standarda EN 50290-2-1 in so posebej namenjeni za podporo aplikacij ICT in BCT (telefon, računalnik in TV), kot določa EN 50173-4. Kabli, zajeti v tem evropskem standardu, so namenjeni za delovanje pri napetostih in tokovih, ki so običajni v komunikacijskih sistemih. Ti kabli niso namenjeni za uporabo z viri z nizko impedanco, na primer z električnim napajanjem javnih omrežij. Vendar so kabli, zajeti v tem evropskem standardu, lahko izpostavljeni napetostim do 300 V izmenične napetosti ali 450 V enosmerne napetosti in morajo biti skladni z zahtevami direktive o nizki napetosti. Največji tok na prevodnik je 3 A/mm, razen če je v ustrezni podrobni specifikaciji navedeno drugače.

The summary below is based on the supplied EN 50441-1:2012 material.

Overview

EN 50441-1:2012 specifies constructional details, performance requirements and test methods for unscreened cables for indoor residential telecommunication installations (grade 1) characterized up to 100 MHz. These cables support ICT and BCT applications (telephone, computer and TV services) in residential buildings and comply with applicable Low Voltage Directive limits (≤300 V a.c. or ≤450 V d.c.). The standard defines physical construction, electrical parameters and marking/delivery requirements to ensure reliable in‑building cabling.

Key topics and technical requirements

• Cable construction
  • Conductors: solid annealed copper, minimum 0.5 mm diameter (EN 50290-2-1).
  • Elements: pairs or quads; cables contain at least 4 pairs or 2 quads.
  • Insulation: polyethylene (EN 50290-2-23) with thickness to meet electrical specs.
  • Sheath: thermoplastic compound (EN 50290-2-27 or EN 50290-2-22); default cream colour; minimum sheath thickness ≥0.5 mm.
  • Ripcord and clear identification (sheath marking or identification thread).
• Mechanical & environmental
  • Sheath integrity (spark testing), bending and abrasion tests per referenced EN 50289 and EN 60811 methods.
  • Fire behaviour tested to EN 60332-1-2.
• Electrical performance (up to 100 MHz)
  • DC conductor resistance, dielectric strength, insulation resistance.
  • High-frequency characteristics: attenuation, characteristic impedance, return loss, velocity of propagation.
  • Electromagnetic behaviour: crosstalk (NEXT/PSNEXT) and unbalance attenuation (ELFEXT/PSELFEXT).
  • Maximum current rating 3 A/mm² unless otherwise specified.
• Marking & delivery
  • Mandatory sheath/drum marking: standard designation, fire reaction class, supplier name, batch and length.
  • Delivery ends capped to prevent moisture ingress.

Applications and who uses it

• Practical for residential ICT/BCT cabling: in‑home telephone, broadband, TV and network installations.
• Used by:
  • Cable manufacturers for product design and compliance.
  • Building designers, installers and integrators specifying in‑building cabling.
  • Procurement officers and spec writers preparing technical tender documents.
  • Test laboratories performing compliance measurements (attenuation, NEXT, return loss).
• Ensures interoperability with generic cabling systems (EN 50173-4) and compatibility with common connector/installation practices.

Related standards

• EN 50290-2-1 (common design rules)
• EN 50173-4 (ICT generic cabling – residential)
• EN 50289 series (test methods for electrical/mechanical characteristics)
