EN342 Ensembles and Garments for Protection Against Cold
Workwear Clothing Certification Explained.
The EN 342:2004 standard related to clothing designed for protection in cold environments ranging from chill (-5°C) through to cold store (-25°C) to deep freeze (-40°C).
The EN342 standard is determined by four parameters (a,b,c,d) all detailed below:
The standard does not contain any specific requirements for head, hand or foot protection. however, sufficient protection must be worn along with a thermal base layer for this certification to apply.
EN342
a
Thermal insulation properties with motion Indicates the thermal insulation of the garment in (m2.K/W), the higher the value the better the insulating properties. The (B) indicates that the item has been tested with thermal undergarments.
b
Thermal insulation properties without motion (optional) This is an optional test which is measured the same as parameter a, but without any motion factored in.
c
Air permeability (1-3) This indicates breathability of a garment, (1 highest, 3 lowest) breathability. A high air permeability allows for proper dry evaporative heat loss required to keep you warm and comfortable.
d
Waterproof penetration properties (1-2 optional) Determines waterproof properties - this is not a requirement as garments being used in sub zero temperatures do not require waterproofing capabilities.
