EN 511 Protective Gloves In Contact With Cold Testing Device

The Protective Gloves Contact Cold Tester is designed and manufactured according to the EN 511 hand protection cold gloves test standard. This device tests the temperature drop value when gloves come into contact with cold surfaces, enabling calculation of glove thermal resistance. It is primarily used to evaluate gloves' ability to resist hand heat loss and simulate performance against low-temperature injuries in cold environments.

Applicable Standards

GBT 38304-2019 - Hand protection, cold-weather gloves
EN 511
