ISO 15831
Measures insulation of the complete clothing combination on a moving thermal manikin, using the parallel calculation model.
Minimum Icler: 0.265 m²·K/W, with the tested underclothing configuration stated.
EN 342
Clothing ensembles and garments for protection against cold
Requirements & test methods
EN 342 evaluates clothing ensembles for cold environments at or below −5 °C through manikin insulation, air permeability and optional water resistance.
Activity, wind and exposure
Estimates heat balance for different air speeds and exposure durations.
Example: Icler = 0.310 m²·K/W; moving wearer at 115 W/m².
| Air speed | 8-hour exposure | 1-hour exposure |
|---|---|---|
| 0.4 m/s | −2 °C | −18 °C |
| 3 m/s | +6 °C | −8 °C |
ISO 9237
Measures air permeability in mm/s across three classes.
Class 3: ≤ 5 mm/s.
Water resistance and moisture transfer
Optional assessment of water penetration and water-vapor resistance.
Water pressure in Pa; water-vapor resistance in m²·Pa/W.
