Over deze norm
This European Standard deals with the technical requirements to minimize the specific railway hazards of self-propelled road-rail machines - henceforward referred to as machines - and associated equipment, which can arise during the commissioning, the operation and the maintenance of machines when carried out in accordance with the specification given by the manufacturer or his authorized representative when designed and intended for running, travelling and/or working on urban railways only. Where a machine is designed and intended for use on mainline and urban rail the most onerous conditions of prEN 15746-1 and prEN 15746-4 will need to be complied with. The requirements in this standard amend those in prEN 15746-1 as required for the use of the machine on urban railways. This European Standard does not apply to the following: - the requirements for quality of the work or performance of the machine; - the specific requirements established by the machine operator for the use of machines, which will be the subject of negotiation between the manufacturer and the controller of an urban railway; - moving and working while not on rails; - separate machines temporarily mounted on machines and associated equipment. This European Standard does not establish the additional requirements for the following: - operation subject to special rules, e.g. potentially explosive atmospheres; - hazards due to natural causes, e.g. earthquake, lightning, flooding; - working methods; - operation in severe working conditions requiring special measures, e.g. work in tunnels or in cuttings, extreme environmental conditions such as: freezing temperatures, high temperatures, corrosive environments, tropical environments, contaminating environments, strong magnetic fields; - hazards occurring when used to handle suspended loads which may swing freely. For a road-rail machine it is assumed that an EU road permissible host vehicle will offer an accepted safety level for its designed basic functions before conversion. Unless explicitly stated otherwise in a particular clause this specific aspect is not dealt with in this European Standard. Other track construction and maintenance machines used on railway tracks are dealt with in other European Standards, see Annex B.
