New Ramp and Stair Building Code

The national building code has been updated (August 2016)and now provides a very specific requirement for sliptesting –
It has been advised that new ramps and stairs must be tested under AS4586 by a NATA accredited laboratory –

Building Sign off Inspectors are increasingly wanting to see a NATA TEST REPORT before compliance and handover for the development can be given

And we at Sliptest Australia Pty Ltd can do this for you – So before handover book your Sliptest in and let us certify the surface for you

Slip-resistance requirements for housing

From 1 May 2016, the Queensland variation of the Building Code of Australia (BCA) Volume 2 for slip-resistance on stairs lapsed.

Australian Standard 4586 – 2013 ‘Slip-resistance classification of new pedestrian surface materials’ will now apply to class 1 and 10 buildings in the 2016 edition of the BCA.

Prior to this, the requirements have only applied to building classes 2–9 within Volume 1 of the BCA, as adopted in 2014.

Since that time, the differences in slip resistance between Volume 1 and 2 have been aligned in the draft 2016 BCA.  Slip-resistance classifications are now proposed for all stair treads, ramps and landings for all building classes.

For contractors in the residential sector, application of finishes to these areas must have documentary evidence to prove the classification. This applies to all finishes and surface types, including carpet, tiles, timber, vinyl, concrete and metal.


What do contractors have to do?

  • Identify the slip-resistance classification for stair treads, ramps and landings in  wet or dry surface conditions
  • Source and install products with the correct classification
  • Obtain documentary evidence that states classification, as per AS 4586
  • Documentary evidence must be from an organisation registered by the National Association of Testing Authorities (NATA), or a product certification body accredited by the Joint Accreditation Scheme of Australia and New Zealand (JAS–ANZ)
  • Provide copy of documents to the Building Certifier.


Slip-resistant classifications

The BCA uses two types of classifications. The wet pendulum test gives a slip-resistant value as a P classification, ranging from P0 to P5. The oil wet inclining test gives a slip-resistant value as an R classification ranging from R9 to R13. Higher classifications indicate a good slip-resistance value.

Currently, the classifications are applicable as follows:

Volume 1 – Class 2 to 9 

This requires a classification not less than that listed in Table D2.14 for:

  • A floor surface of a ramp; and
  • A surface of a tread or the nosing strip on the tread; and
  • A surface of a landing or the strip at the edge of the landing;
