Section 2.1 on slip resistance of walking surfaces is revised and references AS 4586: 2013 ‘Slip resistance classification of new pedestrian surfaces’. Paragraph 1.2.1 includes a requirement for maximum vertical variations in flooring. BS EN 14975: 2006 ‘Loft ladders – Requirements, marking and testing’ is referenced as an acceptable solution. AS 1657: 2013 ‘Fixed platforms, walkways, stairways and ladders – Design, construction and installation’ replaces an earlier version. Minor changes and corrections are made throughout the text for clarity.

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.
