This European Standard, together with part 1, deals with all significant hazards for road surface cleaning machines when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer associated with the whole life time of the machine (see Clause 4). The requirements of this part are complementary to the common requirements formulated in prEN 17106-1:2017. This European Standard does not repeat the requirements from prEN 17106-1:2017, but adds or replaces the requirements for application for road surface cleaning machines.
