SKID RESISTANCE AND FRICTION TESTER STANDARD AZA0985

The AZA0985 Skid Resistance & Friction Tester is a precision mechanical instrument designed to measure the coefficient of friction and skid resistance of pavement surfaces. Based on the pendulum operating principle, it accurately determines Skid Resistance Value (SRV) / British Pendulum Number (BPN) for both wet and dry surfaces.

This equipment is widely used by highway authorities, airport maintenance teams, civil engineering laboratories, and R&D institutions to ensure surface safety and compliance with international standards.

Key Features

  • Tests skid resistance of roads, runways & industrial floors

  • Conforms to ASTM E303 and BS 812 Part 114 standards

  • Fully mechanical pendulum system – no power required

  • Heavy-duty base with spring-loaded arm mechanism

  • Portable and field-friendly design

Description

Why This Test Is Important

Low surface friction increases the risk of accidents, especially in wet or high-speed conditions. The AZA0985 helps engineers and inspectors verify that surfaces meet minimum safety requirements before opening them for public use.

Working Principle

A spring-loaded pendulum arm fitted with a standard rubber slider is released to swing across the test surface. As it contacts the surface, part of its energy is lost due to friction.

The remaining energy is displayed as a reading on the calibrated scale, expressed as:

SRV (Skid Resistance Value) or BPN (British Pendulum Number)

Higher readings = Safer surface

Applications

  • Road and highway pavement testing

  • Airport runways & taxiways

  • Footpaths, pedestrian zones & industrial floors

  • Material research and development labs

  • Government road safety audits
