BS EN 61482-2-2020 Live working – Protective clothing against the thermal hazards of an electric arc Part 2: Requirements. 4.1 General General requirements for protective clothmg against the thermal hazard of an electric arc which are not specifically covered in this document shall be in accordance with ISO 13688. 4.2 Design requirements for protective clothing Garments protecting the upper part of the body shall have sleeves which extend to provide full coverage to the wrists and shall provide coverage up to the neck. Garments protecting the lower part of the body shall provide full coverage from the waist to the ankles. Closures of the garment shall be designed in a way that the opening function is still present after being exposed to an arc when tested according to 5.2.5. Accessories (e.g. labels, badges, retro-reflective material) and closures used in garment construction shall not contribute to the severity of the injuries to the wearer in the event of an electric arc and related thermal exposure when the clothing is tested according to the garment test in 5.4. Separation of the closure shall not occur. Sewing thread utilized in the construction of garments shall be made of an inherently flame- resistant fibre and shall not melt when tested according to 5.2.5. Threads in seams that have no influence on protection, e.g. hems, pocket seams, need not be flame resistant. No uncovered outside metal parts shall be permitted in the clothing. Hardware penetrating the outer material of the garment shall not be exposed to the innermost surface of the garment. All exposed parts of a garment shall be made of arc thermal protection materials. In case different materials are used for the front and back of the garment, the exact information shall be given in the instructions for use where the weakest area is located (e.g. by means of a drawing of the garment including dimensions and warning indication). NOTE 1 The user can carry Out a hazard risk assessment to determine the level of protection needed. Documents such as NFPA 70E, IEEE 1584, ISSA Guide, and DGUV-l 203-77 help to assess hazards from the practical perspective, For garments covering torso and arms, the front side and the sleeves all around the arms and over their complete length shall fulfil the same arc thermal protection. For garments covering legs, the front over the complete length shall fulfil the same arc thermal protection. For...
