The EN 342 standard specifies requirements and test methods for the performance of clothing ensembles (i.e., two-piece suits or coveralls) for protection against the effects of cold environments equal to or below -5 °C. These effects comprise not only low air temperatures, but also humidity and air velocity.
Tested for:
Thermal insulation: measured with a mannequin in motion (Icler) it must have a minimum value of 0.265 m2K/W
Air permeability (AP): the permeability of the fabric is measured and divided into 3 classes, with 3 meaning maximum protection. This value is optional.
Water impermeability: this regards protection against water penetration. If declared, the material must have a minimum value of 8000 Pa,
This value is optional. If present, it must also determine the aqueous vapour transmission coefficient that must not be higher than 55 m2Pa/W.
