Overview

EN 60332-2-1:2004 (CLC / IEC 60332-2-1) defines the test apparatus used to assess vertical flame propagation for a single small insulated electrical conductor, cable or optical fibre cable under fire conditions. This European adoption of the IEC standard is a group safety publication (IEC Guide 104) and specifies only the physical set‑up and equipment requirements - the actual test procedure and performance recommendations are given in EN 60332-2-2.

Key topics and technical requirements

• Scope: Apparatus for testing resistance to vertical flame spread of a single small insulated wire or cable (electrical or optical).
• Primary components:
  • Metallic screen: dimensions (1 200 ± 25) mm high × (300 ± 25) mm wide × (450 ± 25) mm deep; open front, closed top and bottom.
  • Ignition source: a propane burner (diffusion flame) complying with the detailed burner drawing; an 8 mm bore adaptor is permitted where needed.
  • Chamber: a draught‑free enclosure with exhaust for noxious gases; maintained at (23 ± 10) °C.
• Burner fuel and flame:
  • Propane of >95% purity.
  • Gas flow adjusted so the luminous flame length is (125 ± 25) mm.
• Safety and operational notes:
  • Chamber should be substantially free from draughts; a fume cupboard may be used if extractor fan can be independently turned off and outlet sealed.
  • Recommended safe practices for fume cupboards (seal outlet, operate extractor OFF, controlled door gap, evacuate before opening).
• Normative references: IEC 60695-4 (fire test terminology) and IEC Guide 104 (safety publications).

Applications and users

EN 60332-2-1 is intended for:

• Cable manufacturers and materials suppliers validating flame‑resistant constructions.
• Independent test laboratories establishing compliance with vertical flame tests.
• Certification bodies and regulators reviewing fire performance claims.
• Product designers, safety engineers and procurement teams specifying cable fire performance for buildings, transportation, telecoms and industrial installations. Practical uses include apparatus set‑up for vertical flame testing, equipment procurement, standard test lab configuration, and ensuring comparability of test results across laboratories.
