Description and Specification for Lab Tenders
Split Tear Tester.
Micro cellular sheets used in the manufacture of hawai chappals and
shoe soles should be resistant to slitting if they get split across
their thickness. & The ability of micro cellular rubber sheets
and soles to resist propagation of splits is determined by splitting a
rectangular test specimen taken from the sheet or sole under test across
its thickness and pulling the two split ends away from each other. The
maximum load exerted before failure gives the measure of the resistance
of the sheet or sole under test to splitting. & The Split Tear
Tester for microcellular sheets and shoe soles consists of an
arrangement to hold two split tongues of the test specimen in two
separate grips in a vertical plane, an arrangement to move one of the
grips downward at a specified speed, and an arrangement to record the
maximum load exerted while propagating the split.
