1.1.1 This British Standard specifies requirements for the design, materials, workmanship and construction (including storage, transportation and installation) and testing of components for steel and aluminium alloy pedestrian restraint systems.
Other materials such as cast iron, timber, masonry, brickwork or plastics are not at present covered by this standard.
Systems covered by this standard are not designed to protect pedestrians by containing vehicle impact and if this is required reference should be made to BS 6579-1 to Bs 6579-8 and BS 6779-1 and BS 6779-2.
1.1.2 Annex A and Annex B provide information on the layout of pedestrian restraint systems and visibility and inter visibility respectively.
NOTE For barriers in and about buildings see BS 6180. For general fencing see BS 1722. For steel, aluminium and concrete vehicle and vehicle/pedestrian parapets see BS 6779-1 and BS 6779-2. For vehicle safety fences and safety barriers see BS 6579-1 to BS 6579-8.
Specifies requirements for pedestrian and other non-vehicle user restraint systems in metal for use on roads and highways
