Short span compression tester

Bursting Strength Tester (Mullen method)

The Short Span Compression tester is used for paper or board stripes with 15 mm width. The jaws clamps the stripe with definite force and then the clamps move from 0,7 mm towards the middle till a break is detected. On the touch screen display the curve is displayed and the value is shown.

 

Test Description

The sample is put into the open clamps. By pressing the start-button
the clamps close and move together with a speed of 3 +/- 0,1 mm/
min. The curve is displayed and as soon the break is detected, the
value is shown on the touch screen. After several tests the statistic
values and the ratio between MD and CD are displayed. Optionally a
sample feeder can be delivered, which moves the sample stripe for
the next test sequence. The sample feeder moves the sample approx.
3 cm and allows several tests on one stripe.
