ASTM D813 De Mattia Rubber Flexing Fatigue Tester Vulcanized Rubber Crack Growth Testing Machine for Laboratory CF8390

ASTM D813 De Mattia Flexing Fatigue Tester CF8390

The CF8390 De Mattia Flexing Fatigue Tester evaluates the resistance of vulcanized rubber and elastomeric materials to crack growth and flex fatigue under repeated bending cycles per ASTM D813 and ISO 132. This test is critical for rubber products subjected to dynamic flexing, including tire sidewalls, conveyor belts, automotive hoses, and footwear soles.

Key Features

• ASTM D813 & ISO 132 Compliant: Standard De Mattia flexing method with specified grip geometry and stroke for reproducible crack growth measurement.
• Multi-Station Design: 12-station test capacity with individually adjustable grips allows simultaneous testing of multiple specimens for statistical significance.
• Precision Stroke Control: Adjustable stroke from 0-100mm with 57mm standard setting ensures accurate bending amplitude per ASTM specifications.
• Digital Cycle Counter: High-capacity 6-digit counter with auto-stop at preset cycle count, plus individual cycle tracking for each station.
