Technical specifications
The Pendulum is based on the Izod principle: a pendulum consisting of a tubular arm rotates about a spindle attached to a
vertical pillar. At the end of the tubular arm a head of constant mass is fitted with a rubber slider.
The pendulum is released from a horizontal position so that it strikes the sample surface with a constant velocity.
The distance travelled by the head after striking the sample is determined by the friction of the sample surface. A reading of Skid Resistance Values is obtained.
