Foam Fatigue Tester

The IFD tester is a benchtop, low-cost foam indentation force-deflection (IFD) tester. This IFD tester can also perform indentation load-deflection (ILD) testing. Both test methods are used to determine the hardness, stiffness, or load-bearing capacity of polyurethane foam. The tester can test samples up to 24 inches square and 8 inches thick. The tester uses a manually operated variable-speed DC motor with a speed adjustment range of 5.0 mm/s to 0.5 mm/s.

Standards:

Complies with the compression speed requirements specified in ASTM D3574-95. (This ASTM standard requires a test speed range of 3.3 mm/s to 0.83 mm/s).

Technical Specifications:

1. The maximum load of the foam IFD tester is 1500 psi. The drive unit is mounted on a custom aluminum structure with a lower load-sensing platform topped with a ventilated top plate (ASTM compliant) for placing the test sample.
2. This load-sensing platform is equipped with a digital force reading display.
3. The foam contacts a supplied 203 mm diameter indenter, which is mounted on the power-driven actuator via a flexible pivot connection (ASTM compliant). Foam displacement is measured by a precision digital scale on the front of the machine.
4. While tensile testing is not included in ASTM D3574. the foam IFD tester can perform tensile tests with optional configurations.
5. The standard dimensions of the foam IFD tester (including the stroke of the DC power load unit) can be adjusted to your needs. Contact us for a quote on a standard design or custom equipment to meet your specific specifications. The tester comes with a load cell of your choice.
