1.1.1<\/b> 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.<\/p>\n

Other materials such as cast iron, timber, masonry, brickwork or plastics are not at present covered by this standard.<\/p>\n

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.<\/p>\n

1.1.2<\/b> Annex A and Annex B provide information on the layout of pedestrian restraint systems and visibility and inter visibility respectively.<\/p>\n

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.<\/p>\n<\/blockquote>\n
