This European Standard specifies the safety requirements applicable to stationary and relocatable mixing plants for the production of materials (e.g. hot-mix asphalt, cold-mix asphalt, cement gravel) used for the construction and maintenance of traffic routes (roads, highways, sidewalks, airfields, etc.) water retaining works, dam walls, culverts, etc.
This European Standard applies to the following types of mixing plant:
a) hot Asphalt mixing plant;
b) cold mixing plant (e.g. for production of cement gravel, cold mix asphalt);
c) mixing plant for bituminous or non-bituminous reclaimed materials;
d) mixing plant for mastic asphalt, also including natural asphalt.
Machines moving during the working process (e.g. mobile mastic asphalt mixers) and crushers are not covered by this European Standard.
Those types of asphalt mixing plants can also be combined or enlarged by additional installations (e.g. Plant for storage of binders (e.g. bituminous, synthetic, vegetal).
This European Standard deals with all significant hazards pertinent to mixing plants, when they are used as intended and under the conditions of misuse which are reasonably foreseen 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 does not apply to machines for the production of cement concrete and mortar as covered in EN 12151.
This European Standard does not deal with hazards caused by flammable gases. As soon as information is available it will be included.
This European Standard is not applicable to mixing plants for road construction materials, which are manufactured before the date of publication of this European Standard by CEN.
