Digital Foam Indentation Force Deflection Tester

Computer-controlled indentation tester that presses a circular indenter into flexible foam to measure the force needed at 25, 40 and 65 percent deflection. Used in mattress, cushion and automotive seat foam quality control per ASTM D3574 and ISO 2439.

Specification

The tester drives a 200 mm diameter indenter foot into a foam block at constant speed while a load cell records force against deflection. Support factor and hardness are computed automatically for batch comparison. It is a core instrument in furniture and bedding foam laboratories.

Features

• Motor driven crosshead with constant 50 mm/min speed
• Interchangeable 323 cm2 circular indenter foot
• Load cell with digital force display and PC software
• Automatic calculation of IFD at 25, 40 and 65 percent and support factor
• Adjustable limit switches protect load cell
