Foam Tear Strength Tester with Trouser Specimen Fixture

Tear testing machine with trouser-type grips that measures the force to propagate a cut through flexible polyurethane foam. Used by foam and bedding manufacturers to qualify material under ASTM D3574 Test F.

Specification

A pre-cut specimen is gripped in two arms and pulled apart at constant speed, recording the force needed to extend the tear. Peak and mean tear forces are reported in N/m. It gives a quick indication of foam cell structure and processing quality.

Features

• Low capacity 100 N load cell for soft foams
• Wide pneumatic grips for thick specimens
• Speed control from 50 to 500 mm/min
• Automatic tear strength calculation in N/m
• Tear initiation cut template included
