EN 14058

EN 14058

Protective clothing for protection against cool environments

Cool environments are characterized at temperatures > -5 °C. This can be outdoor clothing, but also clothing for the construction- or food industry. That’s why air permeability (wind) and water-resistance are optional.

The contents of this standard

5 values can be found next to the pictogram. From top to bottom:

a) Rct: thermal resistance class, measured on all textile layers together

b) Air permeability (optional), measured on all textile layers together

c) Water penetration resistance (optional)

d) Optional: Thermal insulation, calculated for a moving mannequin (Icler)

e) Optional: Thermal insulation, calculated for a stationay mannequin (Icle)

An “x” in front of the value means that the characteristic is not determined.

 

Different tests

a) Rct value: is measured on all textile layers together and results in the insulation value. The EN14058 is divided in 3 classes. The higher the class, the better the insulation.

Protective clothing for protection against cool environments

If the Rct value is > than 0,25, then we assume the EN342 applies.

b) Air permeability: is optional and is divided in 3 classes (the higher the class, the better the air permeability and the better the insulation):

c) Water penetration resistance: is optional and is divided in 2 classes. The water-resistance of textile and seams is indicated in Pa (the same test as EN343, but is divided in different classes):

Water penetration resistance: is optional and is divided in 2 classes.

When the water resistance of the garment is indicated, the water vapour permeability (or the garment’s breathability Ret) must also be determined. The Ret of all layers must not be higher than 55.

d) and e) are optional. They respectively stand for the Icler en Icle. These are, respectively, the moving and the stationary mannequin test. The minimal value for Icler is 0.170 and for Icle 0.190.

 

The requirements set in this standard

There are no model requirements for this standard. However, the modeling and layer structure strongly influence the insulating values. In the Annex D of this standard (just like EN342) a few characteristics are standardly included (for example, a jacket or coat should be closeable up to the collar or neck band, they should be adjustable at the waist line to allow for close fitting and the trouser bottoms should be adjustable to give a close fit. Jackets should be long enough to cover the tops of the trousers even when the wearer is bending over).
