Th

24、e work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-gov

25、ernmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.Th

26、e main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote

28、 ISO 2013 All rights reservedBS EN ISO 28881:2013ISO 28881:2013(E)IntroductionThis International Standard has been prepared to be a Harmonized Standard to provide one means of conforming to the Essential Safety Requirements of the Machinery Directive of the European Union and associated EFTA regulat

29、ions.This document is a type-C standard as defined in ISO 12100:2010.The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the Scope of this International Standard. In addition, electro-discharge machining (EDM) equipment and EDM system

30、s are intended to be designed according to the principles of ISO 12100 for hazards which are not dealt with in this International Standard.When requirements of this type-C standard are different from those which are stated in type-A or -B standards, the requirements of this type-C standard take prec

31、edence over the requirements of other standards for machines that have been designed and built according to the requirements of this type-C standard.This International Standard defines performance level and safety categories of the safety-related parts of the control system for EDM equipment and EDM

32、 systems as defined in ISO 13849-1:2006.The requirements of this International Standard concern designers, manufacturers, suppliers and importers of machines described in the Scope.This International Standard also includes a list of informative items intended to be provided by the manufacturer to th

33、e user. ISO 2013 All rights reserved vBS EN ISO 28881:2013Machine tools Safety Electro-discharge machines1 ScopeThis International Standard specifies safety requirements and/or protective measures, applicable to EDM equipment and EDM systems, such as manually controlled EDM die sinking or EDM drilli

34、ng machines, numerically controlled EDM die sinking or EDM drilling machines, and numerically controlled EDM wire cutting machinesintended to be adopted by persons undertaking the design, construction, installation and/or supply of such equipment. This International Standard also includes informatio

35、n to be provided by the manufacturer to the user.This International Standard is not applicable to arc eroding and electro-chemical machining equipment.This International Standard takes account of the precondition of the intended use as well as the reasonably foreseeable misuse, in normal workshop en

36、vironments and non-explosive atmospheres, including transportation, installation, setting, maintenance, repair and dismantling for removal or disposal of EDM equipment and EDM systems.This International Standard is also applicable to auxiliary devices essential for EDM processing.This International

37、Standard deals with all significant hazards, hazardous situations or hazardous events relevant to EDM equipment and EDM systems, where they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).This International Standard is intended

38、to apply to machines manufactured after the date of publication of this International Standard.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
