Overview

The Compressibility Test Rig is an advanced, ISO 6310-compliant machine designed to measure the compressive strain and displacement of brake linings and pads under varying load and temperature conditions. It evaluates the thermal swell, growth, and mechanical compressibility of friction materials — essential parameters for braking system performance validation.

Key Features

• Complies with ISO 6310:2009(E) standards

• Tests brake pads, shoes, and coupon samples

• Performs Cold & Hot Compressibility Tests (up to 400 °C)

• Servo-pneumatic control system for precise load application

• Real-time data acquisition and report generation software

• Integrated calibration module and automated test scheduling

• NI USB- DAQ Card for accurate signal processing

• Compact, safe, and fully automated system
