Springiness is a measure of how far the sample returns after being compressed to the target

deformation.

Adhesiveness is a measure of stickiness and is calculated as the area under the negative peak as

probewithdrawsaftertherstcompression.

TENSION TEST–thistestcanbeusedtopullapartasample,usuallyusinggripxturestoapply

tension load on the sample.

The operator sets the trigger value, target deformation and the test speed using the Tension menu

screen:

TEST: TENSION

TRIGGER: XXX.X g

DEFORMATION:XXX.X mm

SPEED: XX.X mm/s

The deformation value shown in this screen is the current distance from the top Home position and

as such shows how much travel is possible once the test begins. Be sure this value is greater than

the sum of the distance necessary to reach the trigger plus the programmed target deformation.

When clamping the sample try to exert only minimal lateral loads on the probe shaft. Pressing Start
