This European Standard shall be given the status of a national standard, either by publication

20、 of an identical text or by endorsement, at the latest by July 2000, and conflicting national standards shall be withdrawn at the latest by July 2000. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and support

21、s essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this standard. According to the CENKENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this Euro

22、pean Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. The standards prepared by CENTTC 270 are specific to internal combustion engines and supp

23、lement those A and B standards concerned with safety. Normative and informative annexes to this standard are indicated in the contents list. General Safety requirements for internal combustion engines are given in EN 1679-1:1998. O Introduction This European Standard has been prepared to be a harmon

24、ized standard to provide one means of conforming with the essential safety requirements of the Machinery (98/37/EEC) and ATEX (94/9/EEC) Directives, and associated EFTA regulations. This European standard is a type C standard as defined in EN 292:1991. The extent to which hazards are covered are ind

25、icated in the scope of this standard. In addition, machinery shall comply as appropriate with part I and 2 of EN 292:1991 for hazards which are not covered by this standard. The requirements of this standard apply to designers, manufacturers, suppliers and importers of reciprocating internal combust

26、ion engines. This standard also contains the information to be provided by the manufacturer to the user of reciprocating internal combustion engines. 1 Scope This European Standard specifies the safety requirements and/or measures to remove the hazards and limit the risks on reciprocating internal c

These requirements can be found in the a

29、ppropriate application standards. This European standard does not apply to engines used in premises for the processing manufacture or storage of explosives. The safety requirements for engines for use in potentially explosive atmospheres for underground applications are given in EN 1834-2:ZOOO. The

30、safety requirements for engines for used in explosive atmospheres with combustible dust are given in EN 1834-32000. I This European Standard does not apply to spark ignition engines. The hazards applicable are listed in clause 4 and relate to the additional hazards of operation in an atmosphere that

31、 may become explosive. The tests which the engine and its ancillary fittings are required to undergo to verify compliance with this specification are detailed in this standard. General safety requirements .e. those common to all RIC engines, are covered in EN 1679-1 1998. This European Standard is a

32、pplicable to engines which are manufactured after the date of issue of this standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.
