Digital
Pneumatic Stiffness Tester. Determines fabric stiffness using
the ASTM circular bend test method. A plunger of 25.4mm (1 in)
diameter pushes the fabric through a 38mm (1.5 in) diameter
orifice for a distance of 57mm (2.25 in) in 1.7 seconds and the
maximum force is recorded. Provided with pneumatic cylinder,
controls and battery-operated digital force gauge 50 kgf, 500N
or 100lb (switchable) with peak-hold facility. Laboratory
standard compressed air supply required.
