The standard describes the requirements for protective gloves against cold. The protetive glove should protect the wearer against convection cold and contact with cold surfaces. The standard also provides information about the water resistance.
ABC
Convective cold (A)
For the measurement, a hand model is heated to 35°C. The glove is pulled over this hand model. The power level is based on the energy that must be used to maintain this temperature (30-35°C).
The more energy that can be supplied without increasing the room temperature outside the glove, the better the insulating properties of the glove.
Contact cold (B)
A heated and a cooled plate are separated by the glove material. The basis is again the energy supply that can be supplied to the heated plate without causing a temperature change in the cooled plate.
Waterproofness (C)
Level 1 stand for waterproof, level 0 for not water permeable. Level X means not tested. The waterproofness includes the palm and the back of the hand.
The work to be done is decisive for the selection of the right gloves in cold environments, or the required insulation.
Because the higher the activity of the employee in cold environments, the more energy he will supply to the space in the glove, which is the space to be protected.
However, if the employee hardly moves, or the work does not require any physical activity - greater isolation is required.
