Skid Resistance Tester

About Skid Resistance Tester

A Skid Resistance Tester (also known as a British Pendulum Tester) is a precision instrument used to determine the frictional resistance (skid resistance) of road surfaces, paving materials, and flooring under wet or dry conditions. It is widely used in highway engineering, airport runway testing, and material quality control to ensure safety against skidding accidents.

Key Features:

• Designed as per ASTM E303, EN 1097-8, BS 812 standards
• Portable and field-friendly design for on-site testing
• Equipped with pendulum arm and rubber slider system
• Direct reading scale for skid resistance value (SRV / PTV)
• Adjustable leveling base with three leveling screws
• Supplied with rubber sliders, thermometer, and accessories kit
• Robust construction for laboratory and field use

Working Principle:

The tester operates on a pendulum mechanism, where a rubber slider attached to the pendulum arm swings and contacts the test surface. The loss of energy due to friction is measured and displayed as skid resistance value.

The higher the value, the greater the surface friction and safety against skidding.

Applications:

• Road and highway surface testing
• Airport runway friction testing
• Asphalt and concrete pavement evaluation
• Floor, tile, and ceramic slip resistance testing
• Polished Stone Value (PSV) determination
• Research laboratories and civil engineering institutes

Technical Specifications (Typical):

• Pendulum weight: ~1.5 kg
• Measuring range: 0150 Skid Resistance Value (SRV)
• Test surface: Flat, curved, or gradient surfaces
• Slider: Standard rubber slider (TRL type)
• Instrument weight: ~2530 kg
• Operation: Manual, portable

Standard Accessories:

• Rubber sliders (standard & PSV type)
• Thermometer
• Water bottle / spray
• Tool kit and spanners
• Carrying case
• Calibration certificate

Advantages:

• Provides reliable measurement of surface friction
• Helps prevent road accidents due to skidding
• Suitable for both laboratory and field testing
• Easy to operate and maintain
• Widely accepted international testing method
•
