This Technical Report specifies geometrical and technical requirements for the design and manufacture for pedestrian parapets on road 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 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.
