24、, Sweden, Switzerland and the United Kingdom. 3 EN 12477:2001(E) Introduction There are various manual welding processes, which are defined in ISO 857-1:1998, Welding and allied processes Vocabulary Part 1: Metal welding processes. The nature and the severity of the risks for welders hands vary acco

25、rding to the various welding processes. The performance (protection and dexterity) required for protective gloves can therefore differ depending on their intended use. 1 Scope This European Standard specifies requirements and test methods for protective gloves for use in manual metal welding, cuttin

26、g and allied processes. Protective gloves for welders protect the hands and the wrists during the process of welding and related tasks. Protective gloves for welders protect against small splashes of molten metal, short contact exposure to limited flame, convective heat and contact heat and U.V. rad

27、iation from the arc. !The gloves material provides minimum electrical resistance up to 100V (DC) for arc welding.“ Besides, they protect against mechanical aggressions. !WARNING: It is not meant to bring any protection in case of defective or wrong use of the welding equipment. It does not qualify t

28、he glove for protection against electrical shock where protective gloves designed according to EN 60903 shall be used.“ According to their performance, protective gloves for welders are classified into two types: type A: lower dexterity (with higher other performance), type B: higher dexterity (with

29、 lower other performance). Protective gloves for special welding processes are outside the scope of this standard. 2 Normative references This European Standard incorporates, by dated or undated references, provisions from other publications. These normative references are quoted at the appropriate

During the test for resistance to small splashes of molten metal, if drops adhere to the material, then the mater

For protective gloves with a multilayer construction, the test shall be carried out on all layers simultaneously, even if these, after removal of the test sam

41、ples, are no longer connected to one another. If care instructions are provided, all the tests shall be performed on the gloves, before and after they have been subjected to the maximum recommended number of cleaning cycles. The lowest performance level obtained from either before or after the maxim

The classification is based on the lowest performance level obtained. 6
