Foam IFD Tester

Foam IFD Tester

SCHAP’s IFD Tester is a bench-top, low cost foam Indentation Force Deflection (IFD) tester. The IFD Tester also performs Indentation Load Deflection or ILD testing. Both are a test method for urethane foam to determine firmness, stiffness or load bearing capacity. It is capable of testing samples 24 inches square and up to 8 inches thick.  This tester utilizes a manually operated variable speed DC motor with an adjustable speed range of 5.0 mm/sec to 0.5 mm/sec. This provides the required compression speeds per ASTM D3574-95. (This ASTM specification requires testing to be done within a range of 3.3 and 0.83 mm/sec).

The Foam IFD Tester is capable of a maximum load of 1500 pounds-force. The drive is mounted to a custom aluminum structure with a lower load sensing platform that has a vented top plate (per ASTM specifications) for placement of test samples.

The load sensing platform has a digital force readout display.

Foam contact is made with the provided 203 mm diameter indenter mounted to the power drive actuator with a flexible pivoting union (per ASTM specifications), and foam displacement is measured using a precision digital electronic scale on the front of the machine.

Although not in the ASTM D3574 specification, the Foam IFD Tester is capable of tension testing in an optional configuration.

The standard dimensions of the Foam IFD Tester, including the stroke of the DC powered loading device, can be modified to meet your needs.  Feel free to contact us for a quote on our standard design or a custom unit to meet your exact specifications. This tester is supplied with one load cell of your choosing.
