This European Standard applies to road surface cleaning machines, which are defined in clause 3. The equipment would normally be mounted on a carrier vehicle (e.g. truck, tractor, construction machinery and mobile industrial handling equipment). It is also possible to mount a road surface cleaning machine on its own chassis construction and propulsion system. In all cases the machine and chassis form an integral unit. Directives and standards for the vehicular truck chassis aspect, termed 'carrier vehicle' in this standard, would be those relative to that equipment, even where specific modifications have been made to realize the road surface cleaning application. The use in public road traffic is governed by the national regulations. This European Standard deals with all significant hazards identified through a risk assessment pertinent to road surface cleaning 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 !deleted text" EMC. This European Standard only specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards associated with machine operation, setting and adjustments, load discharge and routine maintenance. This European Standard does not include requirements for the carrier vehicles (e.g. truck) or special constructions. These are covered in directives related to the construction of vehicles. Demountable bodywork systems (e.g. demountable containers) are specified in other standards.
