ISO 15025
Tests the outer face, innermost lining and structural seams before and after cleaning.
EN ISO 14116 Index 3. Afterflame ≤ 2 s; flame spread, debris, holes and seam opening are also assessed.
EN 469
Protective clothing for firefighting activities
Requirements & test methods
EN 469 evaluates firefighting clothing through thermal, mechanical, liquid-protection and physiological requirements.
ISO 9151 / ISO 6942
Measures flame and radiant heat transfer through the clothing assembly. The radiant test uses 40 kW/m²; HTI24 and RHTI24 measure the time to a 24 °C calorimeter rise.
X1 or X2, determined by the lower achieved thermal level.
| Result | X1 | X2 |
|---|---|---|
| Flame: HTI24 | ≥ 9 s | ≥ 13 s |
| Flame: HTI24 − HTI12 | ≥ 3 s | ≥ 4 s |
| Radiation: RHTI24 | ≥ 10 s | ≥ 18 s |
| Radiation: RHTI24 − RHTI12 | ≥ 3 s | ≥ 4 s |
ISO 12127-1 / ISO 17493
Tests contact heat at 250 °C for Level 2, and oven heat at 180 °C for 5 min.
Level 2 contact-heat threshold ≥ 10 s. Oven test: no ignition or melting and shrinkage ≤ 5%.
Mechanical strength
Measures outer material and structural seam strength after cleaning, plus residual tensile strength after radiant-heat exposure.
Outer tensile strength ≥ 450 N; structural seams ≥ 300 N; tear force ≥ 30 N; residual tensile strength ≥ 450 N.
ISO 6530
Tests 30% sulfuric acid and undiluted o-xylene at 20 ± 2 °C, with a 10 s application.
No penetration to the innermost surface and repellency ≥ 80% for each liquid.
ISO 811 / ISO 11092
Measures water penetration pressure and water-vapor resistance of the layers or assembly.
Water penetration: Y1 or Y2. Water-vapor resistance: Z1 or Z2.
| Marking | Result |
|---|---|
| Y1 | Water penetration pressure < 20 kPa |
| Y2 | Water penetration pressure ≥ 20 kPa |
| Z1 | 30 < Ret ≤ 45 m²·Pa/W |
| Z2 | Ret ≤ 30 m²·Pa/W |
Dimensional stability
Measures dimensional change of each material layer after cleaning.
Within ±3% for woven materials and ±5% for knitted materials.
