Protection against the cold is expressed by a pictogram followed by a series of 3 performance levels relating to specific protective qualities.
abc- aConvective cold (x, min. 0, max. 4)
- bContact cold (x, min. 0, max. 4)
- cPenetration by water (x, 0/1 – after 30 min)
Level X means that this test cannot be carried out on this particular glove. The higher the level, the better performance.
A - Resistance to convective cold (Performance level 0 - 4)
Based on the thermal insulation properties of the glove. The power required to maintain a constant temperature on a heated hand model in a climatic room is measured.
B - Resistance to contact cold (Performance level 0 - 4)
Based on the thermal resistance of the glove material when exposed to contact with a cold object.
C - Penetration by water (0 or 1)
0 = water penetrates after 30 minutes of exposure
1 = water does not penetrate after 30 minutes of exposure
