ASI Foam Indentation Hardness Tester, ASI-IFD

Technical Features:
The Foam Indentation Hardness Tester is designed to determine the hardness of flexible 
polyurethane (PU) foam by measuring the force required to indent a foam sample to a 
specified percentage of its original thickness. This method, known as Indentation Force 
Deflection (IFD), is the industry-standard technique for characterising foam comfort 
grades used in furniture, mattresses, automotive seating, and healthcare applications.
The machine compresses the foam sample in a defined sequence — first pre-compressing
to 70% deflection, then measuring load at 25%, 50%, and 65% indentation levels with a 
programmed dwell time at each point. Results are displayed digitally on the load monitor, 
eliminating operator read errors and enabling consistent, repeatable QC testing on the 
production floor
