ZHTest Method: SATRA TM162
Tear strength - Baumann method
April 2017
SCOPE
This method is intended to determine the force required to tear a material. The method is applicable to all types of leather and is generally not used with any other type of material.
PRINCIPLE
A wide slot with tapered ends is cut in the centre of a rectangular test specimen. The slot is then pulled open by a tensile testing machine causing the material to tear from the tapered ends of the slot, see cover photograph. The test is stopped when the tear has propagated to at least one edge of the test specimen. The maximum force required to propagate the tear and the thickness of the test specimen are recorded.
