Pincer grips are mainly used for tesile tests on soft foam materials and elastomers (Dog-bone or standard specimens) at low forces. Pincer Grips can also be used as the upper grip for tear growth and peel tests. The main application of pincer grip is to test flat specimens with re-inforced gripping ends (dog-bone specimens).
The spring pre-tensioning principle enables the pre-gripping force at the start of the test, and keeps the grips open for inserting the specimen. The specimen is then gripped by the pincer action of the Pincer Grips. These grips are opened and closed using a lever. The jaw inserts also can be exchanged.
Advantages of the Pincer Grip:
- Gripping force is proportional to the tensile strength using the self-clamping principle
- Pincer grips are designed to be very simple and for quick gripping of the specimens
- The lateral movement of the pincer grips ensures that the specimens are always loaded centrally with respect to the tensile axis.
- The high temperature resistance and low overall height of the pincer grips makes them suitable for use in temperature chambers.
