The pendulum test apparatus measures  friction (CoF) and provides results as BPN (british pendulum number). The pendulum test is portable and therefore is frequently used on site as well as in laboratory conditions. It is one of the approved test methods under the Australian Standards AS4586 :2013  & AS4663:2013

The test has a number of advantages  over other test methods.

• Portable and used for on site testing
• The most likely test to be used in an investigation following a slip incident
• Wet test using water – the most common contaminant
• Consistent results with minimal operator impact
• Used in conjunction with accelerated wear testing (AWT)

The results in BPN are grouped into categories  of P0, P1, P2 …P5 (highest). Pendulum tests carried out prior to July 2013, were done with a slightly different method of preparation and results were classified as  (lowest) Z, Y, X, W, V (highest).  Tests provided under the previous method with  Z – V results are still current, however they cannot be directly stated as equal to current P0 – P5 results.
