SATRA STD 172 Simple tensile tester

This general-purpose machine has been designed to measure the strength and stretch of a variety of shoe materials with an accuracy sufficient for many requirements of the shoe manufacturers.

It is easy to use and the load and extension values can be easily read. The instrument is suitable for testing most shoe materials if the load does not need to exceed 150lb or 68kg and the extension 100%.

Description

The machine can also be used for the Baumann tear test and jaws STD 172ST, to suit this test, are illustrated in the photograph right. These jaws need to be ordered separately.

In use, a strip of the material being tested is clamped between two jaws, initially, four inches (10cm) apart, which are separated by a hand drive to apply increasing tension. One jaw is fixed to a cantilever beam. The deflection of the end of the beam is proportional to the applied load and is measured by a dial gauge calibrated to give the load directly. The dial gauge is fitted with a maximum-reading device to make it easy to measure breaking loads. The second jaw moves over a scale which gives the extension as a percentage.
