ISO 13668 : DESIGN
Welders’ protective clothing shall be designed without electrical conduction, from the outside to the inside. Shall be checked by visual inspection.Welders’ protective suits shall completely cover the upper and lower torso, neck, arms and legs. Is possible a single garment or a two-piece garment. The jacket of a two-piece suit shall provide a minimum overlap of 20 cm between the jacket and the top of the trousers. This minimum overlap shall be maintained in all positions and in movements encountered during welding.Pockets: if its necessary, shall be constructed with external openings shall be made of materials conforming to ISO 15025, flame spread. External opening pockets including pass through openings shall be flapped except for; side pockets below the waist which do not extend more than 10º forward of the side seam, and a single rule pocket with an opening not grater than 75 mm placed behind the side seam on one or both legs and measured flat. All flaps shall be stitched down or capable of fastening the pocket closed. They shall be 20 mm wider than the opening (10 mm on each side).Closures and seams: closures shall be designed with a protective cover flap on the outside of the garment. The maximum distance between buttonholes shall be 150 mm. If zippers are used, the slide fastener shall be designed to lock when completely closed. Cuff may be provided with closures to reduce their width. The closure and any fold which it creates shall be on the underside of the cuff. Cuff shall not have turn-ups. Necks openings shall be provided with closures.Trousers or one-peace suits shall not have turn-ups. They may have side slits which shall have a means of closure and the slit and closure shall be covered.Overlapping seams on the outside of the garment shall be downward facing and overstitched
