APPENDIX A: The wet pendulum test for measuring slip resistance (AS / NZS 4586 Appendix A) is generally
performed using a pendulum test instrument. The pendulum device is portable and consists of a weighted foot
and a test slider swinging downwards and flowing on a wet surface with water. The foot includes a spring-
loaded rubber slider which exerts a predetermined force on the sample as it slides onto the surface. The test
results are expressed as British Pendulum Number (BPN) and classified according to AS / NZS 4586, as shown
in the following table:

Floors are classified according to their degree of resistance to Rd
slipperiness. The floor is more non-slip as the Rd value increases.
Los suelos se clasifican según su grado de resistencia al
deslizamiento Rd. El suelo es más antideslizante a medida
que aumenta el valor Rd.
