196 Standards EN 407:2020 · DIN EN 511:2016 DIN EN 407:2020 Standard for safety gloves providing protection against thermal risks — heat The European standard DIN EN 407 regulates the requirements for safety gloves that provide protection against thermal risks in applications involving heat. Safety gloves certified according to this standard protect the wearer against contact heat, radiant heat and small splashes of molten metal, for example. However, this does not apply to the specific use of safety gloves in firefighting. According to DIN EN 407, heat protection gloves must have the following features: • low flammability and low flame propagation • low heat transmission (protection against radiant, convective and contact heat) • high temperature resistance The test described in DIN EN 407 assigns safety gloves a performance class in relation to each of the individual thermal hazards. It is important that the glove does not come into contact with open flames if it does not meet the criteria of performance class 3 in the limited flame spread test. Permeability to water (0 to 1) Resistance to contact cold (0 to 4) Resistance to convective cold (0 to 4) Resistance to large quantities of molten metal (0 to 4) Resistance to small splashes of molten metal (0 to 4) Resistance to radiant heat (0 to 4) Resistance to convective heat (0 to 4) Resistance to contact heat (0 to 4) Flame resistance (0 to 4) DIN EN 511:2006 Standard for safety gloves providing protection against thermal risks — cold Cold safety gloves must meet the requirements of the European standard DIN EN 511. The certified gloves below are designed to protect the wearer from penetrating ambient cold and from contact cold through direct contact. Gloves can also be tested for water impermeability in accordance with EN ISO 15383, thus enabling them to protect the hands from wetness and moisture. This test is considered to have been passed if water does not penetrate the safety glove over a 30-minute period. As with mechanical risk protection, the safety glove is assigned a different performance class for each individual aspect. The performance classes are indicated by a number from 0 to 4 next to the pictogram, whereby 4 is the highest performance class. Important changes to standards! In the latest version of DIN EN 407: As of 2020, the first performance class is no longer named “resistance to flammability”, but is now called “limited flame spread”. If the glove has not been tested for this, a new pictogram is used (see above right). However, there are no changes to the performance classes. EN 511 0 1 0 4 2 3 3 4 2 EN 407 EN 407 X 2 3 3 4 1
