Metal testing frequently involves standard tensile tests and these can be performed efficiently and with high accuracy using Zwick’s range of modular testing machines. Various measuring and control systems, load frames and drives are available, backed up by versatile functional and add-on units. The model Z 100, which is a 100 kN Universal Testing Machine, is perfectly suited for the large range of forces required in research, quality control laboratories and especially routine production testing.

This machine is equipped with Zwick’s latest and innovative videoXtens extensometer, specially developed for tests in which contact with the specimen is either impractical or inadvisable. Tensile and compressive deformation in metals and foils are measured in high resolution. VideoXtens can measure longitudinal and transverse strain simultaneously, making it ideal for obtaining r and n values to ISO 10113 and ISO 10275. It has also been developed especially for tests where a traditional extensometer would be at risk from damage occurring at specimen break.
