BS EN 12957 specifies technical safety requirements and measures, applicable to Electro discharge machines (EDM) and EDM systems (e.g. for spark erosion-sinking, spark erosion-wire cutting). It is designed to be adopted by those undertaking the design, construction, installation and/or supply of such equipment. BS EN 12957 also includes information to be provided by the manufacturer to the user.
The design requirements of this standard do not apply to arc eroding and electro chemical machining equipment.
BS EN 12957 takes account of the intended use in normal workshop environment and non explosive atmospheres including installation, setting, maintenance, repair and dismantling for removal or disposal of EDM equipment.
BS EN 12957 also applies to auxiliary devices essential for EDM processing.
