Attention is drawn to the possibility that some of the elements of this document may be the subject of pa

20、tent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes CEN/TR 1317-6:2012. CEN/TR 16949:2016 includes editorial changes with respect to CEN/TR 1317-6:2012 for correcting mistakes which could lead to an incorrect or unsafe application of

21、 the document. PD CEN/TR 16949:2016 CEN/TR 16949:2016 (E) 6 Introduction The safety considerations of pedestrians using road bridges, footbridges and similar elevated structures require the installation of special road restraint systems, so called pedestrian restraint systems or pedestrian parapets.

22、 Pedestrian parapets are used to prevent people from falling off a bridge or other type of elevated structure. Aspects included in the Technical Report are: a) safety in use for pedestrians and other highway users (excluding motor vehicles); b) the safety considerations of pedestrians using road bri

23、dges and footbridges and similar structures; c) analysis and test methods; d) durability; e) labelling and marking. PD CEN/TR 16949:2016 CEN/TR 16949:2016 (E) 7 1 Scope This Technical Report specifies geometrical and technical requirements for the design and manufacture for pedestrian parapets on ro

24、ad bridges, on footbridges, on top of retaining walls and on similar elevated structures. This Technical Report also specifies test methods and provision for the labelling and marking of these products. This Technical Report does not cover: vehicle restraint systems; pedestrian restraint systems in

25、residential, commercial or industrial buildings and within their perimeter; non-rigid rails i.e. rope, cables. This Technical Report may be used for pedestrian parapets on structures which cross over railways, rivers and canals. 2 Normative references The following documents, in whole or in part, ar

46、hould conform to the requirements of this Technical Report. Where a vehicle restraint system is required to also function as a pedestrian parapet, the requirements of EN 13175 should be met.
