I Scope This European Standard specifies the safety requirements and/or measures to remove the hazards and limit the risks on reciprocating internal com

23、bustion compression ignition engines of group I category M 2 for use in underground workings susceptible to firedamp and/or combustible dust hereinafter referred to as engines. The standard does not define requirements relating to the driven machinery. These requirements can be found in the appropri

24、ate application standard. O BSI 04-2000 STD-BSI BS EN Z834-2-ENGL 2000 = lb24bb9 0843943 347 Page 4 This standard does not apply to engines of category M I which require special considerations. This standard does not apply to engines used in premises for the processing, manufacture or storage of exp

25、losives. The safety requirements for engines for use in flammable gas and vapour atmospheres are given in EN 1834-1 :2000. EN 1834-212000 The safety requirements for engines for use in explosive atmospheres with combustible dust are given in EN 1834-3:2000. This standard does not apply to spark igni

26、tion engines. The hazards applicable are listed in 4 and relate to the additional hazards of operation in an atmosphere that 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.

27、 General safety requirements .e. those common to all the RIC engines, are covered in EN 1679- 1 : 1998. This European Standard is applicable to engines which are manufactured after the date of issue of this standard. 2 Normative references This European Standard incorporates by dated or undated refe
