This European Standard deals with all significant hazards, hazardous situations and events relevant to surface finishing machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards. This European Standard deals with the foreseeable lifetime of the machinery including the phases of transport, assembly, dismantling, disabling and scrapping. This European Standard does not deal with:
hand-held grinding machines;
machines intended for operation in a potentially explosive atmosphere;
operation in severe environmental conditions (e.g. extreme temperatures, corrosive environment);
machines intended for outdoor operation. This European Standard is not applicable to machinery which is manufactured before the date of publication of this document by CEN. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
