Multicore and multipair cables for installation above and below ground

HD 627 applies to multicore and multipair rigid and flexible conductor cables for fixed installations having a rated voltage up to 1 kV and operating at a voltagec above 80 V rms. The insulation and sheath may be either thermoplastic and thermosetting, halogenated or halogen free. This Part 1 specifies the General Requirements applicable to these cables; additional or deviating requirements are given in the particular sections of this HD. Test methods are given in EN 60811, HD 21, HD 22, HD 186, HD 383, HD 405, HD 602, HD 605, HD 606, IEC 189 and this HD. The particular types of cables for each category of fire performance are specified in Parts 3 to 7. Cables designed to be installed within the containment area of nuclear power plants (LOCA), or cables specifically designed to be radiation resistant are not included in this HD.

Overview

HD 627 S1:1996 (CLC) defines the general requirements for multicore and multipair cables intended for fixed installation above and below ground. It applies to cables with rigid or flexible conductors and a rated voltage up to 1 kV, designed to operate at voltages above 80 V rms. The standard covers permitted insulation and sheath types (thermoplastic or thermosetting, halogenated or halogen‑free) and directs users to the specific test methods and additional requirements given in the relevant parts of the HD series.

Key Topics

  • Scope & exclusions: Covers fixed-installation multicore and multipair cables for above‑ground and underground use; explicitly excludes cables for LOCA (nuclear containment) and radiation‑resistant nuclear cables.
  • Construction materials: Insulation and sheathing options including thermoplastic, thermosetting, halogenated, and halogen‑free compounds.
  • Voltage rating: Applies up to 1 kV with operational voltages above 80 V rms.
  • General requirements: Mechanical, electrical and dimensional requirements that apply across cable types (Part 1 establishes the baseline).
  • Test methods: References established test standards - EN 60811, HD 21, HD 22, HD 186, HD 383, HD 405, HD 602, HD 605, HD 606, IEC 189 and this HD - for verification of performance.
  • Fire performance: Indicates that particular cable types and fire performance categories are specified in Parts 3–7 of HD 627.

Applications

  • Specification, manufacture and quality control of multicore and multipair cables for:
    • Building and industrial fixed wiring
    • Underground power distribution and control circuits
    • Overhead and conduit installations where fixed cables are required
  • Useful to cable manufacturers, electrical designers, procurement specialists, installation contractors, testing laboratories and compliance officers who need to ensure cables meet CLC/HD general requirements for safety, construction and testing.
  • Helps stakeholders select appropriate insulation/sheath materials (e.g., halogen‑free for reduced toxic emissions) and align cable selection with installation environment and regulatory testing needs.

Related Standards

  • Test and method references: EN 60811; HD 21; HD 22; HD 186; HD 383; HD 405; HD 602; HD 605; HD 606; IEC 189
  • Fire performance and type details: HD 627 Parts 3–7
  • ICS classification: 29.060.20 (Cables)

This summary helps you identify whether HD 627 S1:1996 applies to your multicore or multipair cable project, which tests to consult, and where to look for more specific fire‑performance or construction requirements.
