All of the Acceptable Solutions and Verification Methods relating to D1 are contained in one document.
- D1/VM1 provides a verification method for slip resistance and measuring the coefficient of friction.
- D1/AS1 contains general criteria for variables such as slope, cross fall, changes in level, height clearance and obstructions. It shows means of complying for slip resistance; level access routes and ramps; landings; stairways; fixed ladders and handrails; doors and openings; the movement of vehicles; and lifts. It provides design solutions for access to places of assembly and the accessible accommodation units of communal residential buildings.
