Intuitive software for long-term dynamic tests…
Test & Motion + – DYNPACK – intelligent, intuitive and powerful software that will help you increase productivity and testing quality in your test rooms and testing laboratories. You can streamline, refine, and accelerate your testing and adapt your testing environment to make it easy for operators to measure the mechanical properties of materials in a dynamic single-axis or multi-axis test mode with support for EN, ISO, DIN, ASTM, and GOST standards.
BENTROD system
A solution that can precisely and easily set the coaxiality of a dynamic system…
LABORTECH EP series test load frames exhibit excellent rigidity and coaxiality, which minimizes bending stress to increase test accuracy and reduce data scatter. Proper coaxiality prevents off-axis bending stress, which can degrade the sample (sampling and production is very expensive) or the resulting data will be skewed and therefore unusable. BENTROD measuring and setting unit designed for evaluation and optimization of concentric and edge correction of misalignment (clamping) of clamping jaws for static and dynamic testing machines according to ASTM E1012, GES400 (NADCAP), GE450 and ISOTC 164SC5WG11
