This European Standard applies to winter service machines which are defined in clause 3.This European Standard deals with all significant hazards (see clause 4) identified through a risk assessment pertinent to winter service machines when they are used as intended and under the conditions foreseen by the manufacturer. This European Standard does not deal with significant hazards associated with EMC.This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards associated only with machine operation, setting and adjustments, load discharge and routine maintenance.Winter service machines are normally mounted on carrier vehicles (e.g. trucks, tractors, construction machinery and mobile industrial handling equipment). This European Standard does not cover requirements for the carrier vehicles even where specific modifications have been made to realise the winter service application. These requirements will be handled in directives and standards for the construction of carrier vehicles. The use of winter service machines in public road traffic is governed by national regulations.This standard does not cover any requirements for demountable bodywork systems (e.g. demountable containers). These requirements are specified in other standards.This European Standard does not deal with:-machines or components which are solely designed for clearing rails such as rail sweepers or blowers;-walker-operated and hand-held winter service machines;-highway maintenance machines covered by EN 13524, such as front-mounted sweepers;-machines for the maintenance of sports grounds;-machines for agriculture, horticulture and forestry;-machines intended for use in potentially explosive atmospheres.This European Standard applies to winter service machines which are manufactured after the date of approval of the standard by CEN.
