EN 469 – Protection for Structural Firefighting

Overview
EN 469 defines performance requirements for protective garments used in structural firefighting. It includes requirements for the outer fabric, moisture barrier, and thermal liner, all tested under extreme thermal conditions.

Testing Methods & Minimum Performance Levels

Test Method Description Requirements Min. Performance Level
EN ISO 15025 Procedure A Surface Flame Spread
A small flame is applied to the surface of the fabric for 10 seconds.
  • Self-extinguish within 2 seconds after flame removal.
  • Not produce flaming debris.
  • Hole formation < 50 mm.
 A1
EN ISO 15025 Procedure B Edge Flame Spread
The flame is applied to the bottom edge of a vertically suspended fabric.
  • Self-extinguish within 2 seconds.
  • Not burn the upper or vertical edge.
  • Hole formation < 50 mm.
 A2
ISO 17493 Heat Resistance at 180°C

Fabric is exposed to dry heat at 180°C to evaluate thermal stability.
  • Must not melt, drip, or ignite.
 PASS
EN ISO 9151 Convective Heat (Xf)
Measures heat transfer through the fabric when exposed to flame.
  • Xf1: HTI ≥ 11 s
  • Xf2: HTI ≥ 21 s
 Xf2 (minimum)
EN ISO 6942 Radiant Heat (Xr)
Measures insulation time against radiant heat (20 kW/m²).
  • Xr1: ≥ 7 s
  • Xr2: ≥ 20 s
Xr2 (minimum)
EN 20811 Water Penetration Resistance

Determines resistance to water under hydrostatic pressure.
  • Minimum: 20 kPa
 PASS
ISO 11092 Water Vapour Resistance

Measures breathability to evaluate thermal comfort.
  • Ret ≤ 30 m²·Pa/W
 PASS
ISO 13934-1 Tensile Strength (Strip Method)
Measures the maximum force needed to break a strip of fabric in warp and weft directions.
  • Warp: ≥ 450 N
  • Weft:  ≥ 450 N
 PASS
ISO 13937-2 Tear Strength (Wing Method)

Evaluates resistance to tearing using a trapezoidal-shaped cut and applying load to propagate it.
  • ≥ 20 N (warp and weft)
 PASS
ISO 5077 Dimensional Stability to Washing
Determines shrinkage or growth of the fabric after domestic laundering.
  • Shrinkage should not exceed ±3% (woven)

±5% (knitted)

 PASS
