The Tortus & the Banana Skin
The Australian building and design industry measures the slipperiness of flooring surfaces by two units – the Sigler and the Tortus.
Percy Sigler designed the Sigler Pendulum Skid Resistance Test in the 1940s and motoring authorities around the world have since adopted the Sigler Pendulum Skid Resistance Test for quantifying tyre friction on road surfaces. The Sigler test involves swinging a pendulum at 2.7 metres-per-second across a surface and measuring the energy lost on its upswing after contact between the pendulum foot and the test surface.
The Torus Testing method, meanwhile, was designed by the British Ceramic Research Association. It involves moving a rubber disk across a surface with a velocity of 0.17 metres-per-second. Both are slip resistance value units (SRVs).
Overdone
Feeling overdone
I can’t take the hard decisions anymore
I might just stay on the floor
Close to the door
You’re telling everyone
It seems that I’m deficient and I’m thin
I don’t know where to begin
Put the aspirin in
Never had a better reason
Never need another try
I know it all will come to nothing
If you want a man alive
