ISO 15025
Applies flame for 10 s using surface and edge ignition, before and after cleaning.
Afterflame and afterglow ≤ 2 s. Edge-ignition char length ≤ 100 mm; no flaming or molten debris. Surface ignition also checks holes and seam integrity.
EN ISO 15384
Protective clothing for wildland firefighting
Requirements & test methods
ISO 15384 covers clothing for wildland firefighting and associated work, combining thermal protection, strength and physiological performance.
ISO 6942
Measures radiant heat transfer using Method B at 20 kW/m², before and after cleaning.
RHTI24 ≥ 11 s and RHTI24 − RHTI12 ≥ 4 s.
ISO 17493
Exposes clothing materials to 260 ± 5 °C for 5 min after cleaning. Protected hardware and visibility components have separate 180 °C requirements.
No melting, dripping or ignition; shrinkage ≤ 10%.
Mechanical strength
Measures tensile, tear and main seam strength of woven outer material after cleaning.
Minimum strength in N.
| Property | Method | Minimum |
|---|---|---|
| Fabric tensile strength | ISO 13934-1 | 600 N in each direction |
| Woven fabric tear force | ISO 13937-2 | 25 N in each direction |
| Main seam strength | ISO 13935-2 | 300 N |
ISO 12947-2
Measures resistance to Martindale abrasion after cleaning.
At least 20,000 rubs at 12 kPa under Amendment 1.
ISO 11092
Measures thermal resistance and water-vapor resistance of the material or combination.
Maximum Rct and Ret values.

| Water-vapor resistance Ret | 10 m²·Pa/W |
ISO 5077
Measures length and width change after cleaning.
Within ±3% for woven materials and ±5% for knitted materials.
