Pendulum Skid Resistance Tester AZA1297
Slip & Skid Resistance Measurement System
Model AZA1297
The AZA1297 Pendulum Skid Resistance Tester is a proven, industry-recognized instrument designed to measure the slip and skid resistance of surfaces in accordance with international safety and performance standards. It is widely used to evaluate pedestrian walkways, road surfaces, ramps, tiled floors, industrial workspaces, and sports facilities where slip-related hazards must be controlled and documented.
Based on the energy loss pendulum principle, the AZA1297 provides accurate and repeatable measurements expressed as Pendulum Test Value (PTV) or British Pendulum Number (BPN), enabling engineers, inspectors, and quality managers to quantify surface friction reliably.
Description
Importance of Skid Resistance Testing
Slip and fall accidents remain a major safety concern in public infrastructure, industrial facilities, and transportation networks. Insufficient surface friction—especially under wet conditions—can lead to serious injuries, liability issues, and regulatory non-compliance.
The AZA1297 allows objective assessment of surface friction to:
-
Verify compliance with safety regulations
-
Identify hazardous low-friction surfaces
-
Compare materials during selection or approval
-
Monitor surface wear and performance over time
-
Provide documented evidence for audits and tenders
Working Principle
The AZA1297 operates on a simple yet highly reliable mechanical principle:
-
A pendulum arm with a standardized rubber slider is released from a fixed height.
-
As the slider contacts the test surface, friction causes a loss of kinetic energy.
-
The reduction in swing height is directly proportional to surface friction.
-
This energy loss is displayed as a Skid Resistance Value (SRV / PTV / BPN) on the calibrated scale.
Higher values indicate greater slip resistance and improved safety.
