Handrails must be the right size, strength and shape, conveniently placed for a secure grip and able to carry a user's full weight. On a ramp or stair the rail stands 30 mm to 50 mm clear of the wall with 70 mm of clear height above the bracket, its top is 850 mm to 950 mm above the nosing, floor or landing, and it is either tubular with an external diameter of 32 mm to 50 mm or another profile giving a comparable grip. It extends horizontally at least 300 mm past the first and last nosing of each flight and past each end of a ramp (100 mm is allowed where a door opening intervenes), finishing in a closed end turned down or returned to the post or wall so nothing projects into the route, and it withstands at least 1.3 kN whether the load is applied vertically or sideways. For the Table 2 uses, Braille and tactile information is fixed to the rail. The Best Practice Section covers second lower rails and materials.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
