Protection against cold temperatures - Norm UNE EN 511:1996
This Norm establishes the criterion for protection gloves against convective and contact cold in temperatures of –50°C.
Two things are measured with the glove:
1. how the glove’s material leads cold
2. the material’s insulating capacity (with contact).
The last digit next to the pictogram shows if water penetrates the glove after 30 minutes. The pictogram will be accompanied by a 3-digit code
a) The first digit show resistance to convective cold (performance level 0-4)
b)The second digit show resistance to contact cold (performance level 0-4)
c)The higher performance level the better insulating capacity.
d)The third digit show permeability to water (performance level 0 or 1)
Resistance to convective cold: Termal insulating properties of the glove that are obtained measuring the transfer of convective cold.
Resistance to contact cold: Termal resistance of the material of the glove when it is in contact with a cold object.
Water Resistance: 0 = water penetration after 30 minutes of exposition; 1 = absence of water penetration.
All the gloves must reach at least a level 1 of protection against abrasion and tear.
