Overview

ISO 10047:1993 - Textiles: Determination of surface burning time of fabrics specifies a laboratory method to measure how quickly a raised-fibre fabric surface (napped, pile, tufted, flocked or similar) burns along its surface. The method times the spread of flame downwards from an ignition point to a fixed reference line on a vertically mounted specimen. Results are intended to characterize surface burning time and flame propagation on pile/nap textiles under controlled conditions, not to predict full-scale fire behaviour.

Key topics and technical requirements

• Scope: Applies to fabrics with a raised fibre surface (napped, pile, tufted, flocked).
• Specimen and holder:
  • Specimen size: 150 mm × 75 mm (fabrics narrower tested full width).
  • Frame exposes 125 mm × 50 mm of surface; reference mark is 75 mm below ignition point.
• Ignition and burner:
  • Burner preheated and adjusted to a flame height of 40 mm ± 2 mm.
  • Burner positioned 15 mm from specimen surface so flame contacts ignition point.
  • Gas fuel: commercial propane or butane (or mixtures).
  • Annex A provides burner construction details (gas jet, burner tube, flame stabilizer).
• Conditioning and preparation:
  • Dry specimens in circulating air oven at 105 °C ± 2 °C for ≥1 h; cool in desiccator ≥30 min.
  • Test atmosphere: 10 °C to 30 °C and 15 % to 80 % relative humidity; air movement
