In addition, applicators shall be designed according to the principles of EN ISO 12100:2010 for relevant but not significant hazards (for instance sharp edges), which

32、 are not dealt with by this standard. 5.2 Safety requirements against mechanical hazards 5.2.1 Crushing, shearing and pinching The distances between movable and fixed parts of applicators shall be wide enough to prevent injuries of parts of the human body due to crushing or pinching. 5.2.2 Mechanica

33、l strength Applicators, their fixing elements and the joints for pressurised liquid supply hoses shall be designed and constructed in such a way to withstand the arising forces. External forces (e.g. by dropping atomising or spraying equipment, forces of the supply hoses), shall be taken into accoun

34、t for all applicators. Additionally, the following forces shall be taken into account for applicators for liquid coating material: static hydraulic pressure, dynamic hydraulic pressure (e.g. oscillating supply system pressure), recoil forces during operation, BS EN 1953:2013EN 1953:2013 (E) 13 vibra
