Skid Resistance Tester

Instrument Details

Make               : Wessex Test Equipment Ltd., UK.
Model              : SK1851
Specification : Designed to test road surfaces.

This apparatus measures the skid resistance between a rubber slider (mounted on the end of a pendulum arm) and the test surface. This provides highway engineers with a routine method of checking the resistance of wet and dry surfaces to slipping and skidding, both in the lab and on site.

Working Principles

It is based on the Izod principle, a pendulum rotates about a spindle attached to a vertical pillar. At the end of the tubular arm a head of known 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 is obtained.

Applications

• Road surface testing
• Testing of new road surface materials under development
• Testing of aggregates in the PSV (Polished Stone Value) Test
• Testing of floors and pedestrian walkways
• Flooring materials product development
• Accident investigations, both traffic and pedestrian
• Litigation investigations
• Testing of pavers, in the Flat Bed Polisher

User Instructions

1. Testing should be carried out in accordance with the relevant standard or guidelines.
2. Wipe all flooring materials received for testing in the laboratory, with a clean, dry paper towel to remove all dust prior to testing.
3. It is necessary that at the time of testing the flooring material is flat and securely fixed so as to avoid movement of the sample during testing.
