Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be

20、 held responsible for identifying any or all such patent rights. This document supersedes CEN/TR 1317-6:2012.

21、9:2016CEN/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. Pedestrian parapets are used

22、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 bridges and footbridges and simil

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

24、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 residential, commercial or indu

25、strial 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, are normatively referenced in thi

Where a vehicle restraint system is requ

46、ired to also function as a pedestrian parapet, the requirements of EN 13175 should be met. Figures in Annex E illustrate the constituent parts of a pedestrian parapet. Manufacturers may provide other design types which are not shown in Annex E provided they comply with the requirements of this Techn

47、ical Report. 4.2 Construction 4.2.1 Assembly Design, drawing, installation and maintenance instructions should be provided describing the measures that have to be taken in order to achieve the following performances where they form part of the pedestrian parapet: a) a continuous flowing alignment; b

48、) smooth surfaces; c) the absence of sharp edges that could cause injury to users; PD CEN/TR 16949:2016CEN/TR 16949:2016 (E) 12 d) the provision for expansion, contraction and movement of the main structure (e.g. under traffic loads and temperature effects) so that these do not endanger the performa

49、nce or flowing alignment; e) the avoidance of corrosion pockets; f) the provision for adequate drainage in hollow sections and channels; g) the compatibility between component parts so that there is avoidance of electrolytic action; h) that fixings and fittings cannot be loosened without using tools; i) to demonstrate the ease of assembly at site location, the ease of maintenance and repair including the replacement of parts; j) finish and surface protection; k) any special provisions for end posts/panels.
