7、be conditioned for at least 24 h in an atmosphere having a temperature of (20 t 2) C and a relative humidity of (85 t 3) %. Testing in accordance with EN 1149-2 shall be carried out under these conditions or within 5 min of removal from this atmosphere. The vertical electrical resistance of each dif
8、fering part of the glove or gauntlet including the cuff shall be tested. If the external surface of the glove on its own exceeds the requirements, then only the differing external surfaces need to be tested. However, if the external surface does not pass but the combination of the external surface a
9、nd the lining do meet the requirements, then each differing construction of the glove and cuff shall be tested. - When gloves are intended for arc welding: these gloves do not provide protection against electric shock caused by defective equipment or live working, and the electrical resistance is reduced if gloves are wet, dirty or soaked with sweat, this could increase the risk.
