STANDARD
EN 511:2006
European Standard for Protective Gloves Giving Protection from Cold
EN 511:2006 is the standard that gloves must meet to offer protection against convective cold, contact cold, and water permeability.
The standard specifies the requirements and test methods that glove manufacturers test for A) Resistance to Convective Cold, B) Resistance to Contact Cold, and C) Permeability by Water.
Resistance to Convective Cold
This test determines how well the glove protects against convective cold based on the insulating properties of the glove, which are obtained by measuring the transfer of cold via convection. In a controlled environmental chamber, the glove is placed on a model hand and heated to around body temperature (30-35°C). The chamber is cooled to 20°C below that of the heated hand with constant air flow applied. The electrical power needed to maintain a constant temperature between the surface of the heating hand and the chamber temperature is measured. The greater the electrical energy used indicates lower levels of thermal insulation. The protection level is indicated by a number between 1 and 4, where 4 indicates the strongest level of resistance to convective cold.
Resistance to Contact Cold
This test shows how well the glove protects against contact cold based on the thermal resistance of the glove material when exposed to contact with a cold object. A piece of glove material from the palm side is placed between a warm plate that is heated to around body temperature (30-35°C) and a cold metal plate. An extractor fan is used to cool down both plates and after 30 minutes the measured drop in temperature across the inner and outer surface of the sample is used to calculate the glove’s thermal resistance to contact cold. The protection level is indicated by a number between 1 and 4, where 4 indicates the strongest resistance to contact cold.
Permeability by Water
The third test shows the glove protection against water penetration. The glove is fully submerged in water for 30 minutes. If no water penetration is realized, the glove passes and gets a 1 rating. If any water passes through to the inside the glove it is considered a fail and receives a 0 rating.
Tests are verified by an accredited third party laboratory.
