This standard applies to any gloves to protect the hands against convective and contact cold down to -50℃.
DEFINITION AND REQUIREMENTS
Protection against cold is expressed by a pictogram followed by a series of 3 performance levels, relating to specific protective qualities.
a. Resistance to convective cold (performance level 0-4)
Convective cold resistance: based on the thermal insulation properties of the glove which are obtained by measuring the transfer of cold via convection.
b. Resistance to contact cold (performance level 0-4)
Contact cold resistance: based on the thermal resistance of the glove material when exposed to contact with a cold object.
c. Permeability by water (0 or 1)
0 = water penetration after 30 minutes of exposure
1 = no water penetration
