Winter Insulated Gloves
EN 511 - Cold Environments
Air temperature, wind speed, and moisture present major challenges for working hands in cold environments. EN 511 specifies the requirements and test methods for winter gloves designed to protect against convective and conductive cold down to -50 °C.
CONVECTIVE COLD TEST
Performance Levels 0–4
The glove sample is place on an electrically heated mannequin hand that measures the amount of power required to maintain 30°C and 35°C in a controlled environmental chamber.
The chamber is cooled down to 20°C below that of the heated hand, and constant air flow is applied. The more electrical power required, the lower the thermal insulation rating of the glove.
WATER PENETRATION TEST
Performance Levels 0–1
The glove sample is fully submerged in water for 5 minutes to measure its permeability. If the glove maintains impermeability for the 5 minute duration, it will receive a Level 1 "Pass Rating". If the glove takes on water during the 5 minute duration, it will receive a Level 0 "Fail" rating.
