    Abstract - (Show below) - (Hide below)

    1.1This standard specifies technical safety requirements and measures, applicable to EDM equipment and EDM system (e.g. for spark erosion-sinking, spark erosion-wire cutting), 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.1.2The design requirements of this standard shall not apply to arc eroding and electro chemical machining equipment.1.3This standard 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.1.4This standard also applies to auxiliary devices essential for EDM processing.1.5This standard deals with specific hazards defined in clause 4, Table 1, and the measures of prevention in clause 5, Table 2.1.6This standard applies to machines built after its date of issue.NOTEDirective 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by this European Standard. The present standard is not intended to provide means of complying with the essential health and safety requirements of Directive 94/9/EC.
