This standard speci es requirements and test methods for performance of two piece suits, coveralls or single garments for protection against cold environments (characterised by a combination of humidity , wind and at air temperature lower than -5 °C).

Using S585 thermal rating as an example, a person wearing S585 standing still, can withstand 17 0 C for 1 HOUR and 3 0 C for 8 HOURS .

A person wearing S585 performing light activity can withstand 35 0 C for 1 HOUR and 15 0 C for 8 HOURS A person wearing S585 performing mediumactivity can withstand 58 0 C for 1 HOUR and 38 0 C for 8 HOURS

The following parameters are used: A =Thermal insulation B = Air permeability (Class 1, 2 or 3) C = Resistance to water penetration (optional) (Class 1 or 2) EN 342
