This European Standard defines relevant requirements set out in Annex I of EU Machinery Directive 2006/42/EC, relating to electro-discharge machines which were placed on the EEA for the first time, with the intent of simplifying the means of proving conformity with such requirements. This standard specifies technical safety requirements and measures, applicable to EDM equipment and EDM systems (for example die sinking or wire cutting) intended to be adopted by persons undertaking the design, construction, installation and/or supply of such equipment. This standard also includes information to be provided by the manufacturer to the user. This standard is not applicable to arc eroding or electro-chemical machining equipment. This standard takes account of the precondition of the intended use as well as the reasonably foreseeable misuse, in normal workshop environments and non-explosive atmospheres, including installation, setting, maintenance, repair, and dismantling for removal or disposal of EDM equipment. This standard is also applicable to auxiliary devices essential for EDM processing. This standard deals with specific hazards and the corresponding protective measures.
