1. Introduction:
It is used primarily for testing highly elastic, soft, elastic specimens: plastics and elastomers, films, rubber, etc. with a tensile force of 20 kN.
Opening and closing is carried out by means of a lever. The scissor effect creates a prestressing force at the start of the test. Thanks to the scissor principle, an automatic clamping occurs with increasing tensile force – an advantage for specimens that narrow during the test. Equipped with a lock function.
Clamping jaws have different types of surfaces:
-smooth (G);
-serrated pyramidal (Z);
-notched V-shaped (ЗV), for all types of round samples;
-wavy (B);
-roller with a serrated surface (RZ), used for specimens of the “bone” shape;
