This document applies to road surface treatment machines, which are in particular: - binder sprayers [or sprayers]; - chipping spreaders [or spreaders]; - machines for surface repairs (binder sprayer chipping spreader [or sprayer spreader]); - mastics asphalt mixers; - joint sealer; - micro-surfacing machines/slurry machines; - cold asphalt laying / micro-asphalt-paving machines; (see also Clause 3). Road surface treatment machines can be mounted on a carrier vehicle, trailer or articulated truck, combining to form an integral unit. It is also possible to mount a road surface treatment machine on its own chassis construction and propulsion system (self-propelled or pedestrian-controlled). In all cases the machine and chassis form an integral unit. Directives and standards for the vehicular truck chassis aspects, termed 'carrier vehicle' in this document, would be those relative to that equipment, even where specific modifications have been made to realize the road surface treatment application. The use in public road traffic is governed by the national regulations. This document deals with all significant hazards identified through a risk assessment relevant to road surface treatment machines when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4). This document does not deal with significant hazards associated with pressurized tanks, noise and EMC. This document 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 document does not include requirements for the carrier vehicles 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.
