Slip Rating Requirements

New slip resistance requirements for stairs from 1 May 2014

The Building Code of Australia (BCA) has introduced Deemed to Satisfy (DtS) provisions for determining the slip-resistance to treads and nosing to stairways of all Classes of buildings and pedestrian ramps and landings of Class 2 - 9 buildings.

From 1 May 2014, treads or nosing to treads of a stairway must comply with a slip resistance classification as tested to Australian Standard AS 4586 – 2013 Slip resistance classification of new pedestrian surface materials.  This is a new test method for slip resistance, the old 'X' ratings have been replaced with 'P' ratings.

Coatings must meet, or exceed, the following classifications for stair treads or nosing to treads of a stairway:

  Dry surface Wet surface
Tread surface P3 or R10 P4 or R11
Nosing strip P3 P4
