scope:

This European Standard specifies the technical requirements to deal with the significant hazards, hazardous situations and events, common to demountable machines, as defined in FprEN 15955-1:2012, intended for construction, maintenance inspection of the railway infrastructure, shunting and emergency rescue vehicles. This European Standard specifies the technical requirements to deal with the common hazards during transport, assembly and installation, commissioning, running on track, use including setting, programming, and process changeover, operation, cleaning, fault finding, maintenance and de-commissioning of the machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer; see Clause 4. The common hazards dealt with include the general hazards presented by the machines, and also the hazards presented by the following specific machine functions: - excavation; - ballast tamping, ballast cleaning, ballast regulating, ballast consolidating; - track renewal; rail maintenance; - craning; - catenary renewal / maintenance; - maintenance of the components of the infrastructure; - inspection and measurement of the components of the infrastructure; - tunnel inspection / ventilation; - shunting; - emergency rescue and recovery during commissioning, use, maintenance and servicing. This European Standard applies to self propelled machines that are not intended to operate signalling and control systems. Other similar machines are dealt with in other European Standards; see Annex D. It is assumed that a finished standard automotive chassis used as a host for a demountable machine will offer an acceptable safety level for its designed functions before conversion. This specific aspect is not dealt with in this European Standard. This European Standard does not deal with: a) requirements with regard to the quality of work and the performance of the machine; b) machines that utilise the catenary for traction purposes;d) negotiations between the manufacturer and the machine operator for additional or alternative requirements; e) hazards due to air pressure caused by the passing of high-speed trains at more than 200 km/h; f) requirements which could be necessary in case of use in extreme conditions, such as: 1) extreme ambient temperatures (below - 20 °C or above + 40 °C); 2) highly corrosive or contaminating environment, e.g. due to the presence of chemicals; 3) potentially explosive atmospheres. This European Standard applies to all machines that are ordered one year after the publication date by CEN of this standard. c) specific requirements established by a railway infrastructure manager;
