The ever-increasing importance of environmental testing (temperature chambers, high-temperature furnaces) in materials testing is reflected in the feature, now standard in all test programs, which supports climatic chambers and high-temperature furnaces with multiple heating zones, eliminating the need for software adaptations. This version also permits freely configurable temperature sequences.

In response to strong demand, a data link between testXpert® II and SAP is now available, providing a straightforward means of importing parameter values from SAP and exporting test results from testXpert® to SAP and eliminating manual entry of test results – a source of potential errors.

In addition to the proven RS232 interface, an Ethernet interface can now also be used for linking testControl electronics and the measuring computer.

Convincing industry solutions - Zwick's approach is based on industry-orientated solutions, a concept reflected at testXpo with cross-company, application-based exhibits. The main areas featured included metals, plastics, automotive, medical technology and building materials, with numerous new developments in testing machines and instruments awaiting visitors' attention.

Particular interest was shown in the wide range of mechanical and optical extensometers, their various functions and properties and in using them in combination. Specialist advice was on hand, with pre-tests in the manufacturer's applications laboratory where appropriate, making it possible to find the ideal extensometer for almost any application.

An initiative launched at Zwick in 2005 has seen the introduction of various new products and product improvements in the field of plastics testing. One new arrival is the instrumentation for the new pendulum impact testers in the HIT range, enabling the force - deformation on specimen impact to be measured in addition to absorbed impact energy. Also on show at testXpo17 was the new HIT 230F drop weight tester for instrumented penetration testing and compression-after-impact pre-damage of composites, while tube-testing received a new extensometer for monitoring the inside diameter.

Other exhibits included automated tensile, compression and flexure testing of duroplastic building materials both at room temperature and in environmental chambers, and a further automation project, ideal for research applications, for the measurement of color, glass and opacity.

The metals-testing product range has also been expanded, as seen with Zwick's two new standardized Pellini drop weight testers rated at 550 J (Type P550) and 1,630 J (Type P1630) and featuring a particularly sophisticated safety concept. Of particular interest for steel manufacturers and processors whose production plants operate round the clock is the fully automatic 'roboTest P' testing system for Standard-compliant testing of steel dumbbell specimens up to 2000kN.

Great interestwas also shown in a spring testing machine for the measurement of precision springs from 1 N to 2,500 N, which has extremely good overall measurement technology characteristics, surpassing even the requirements of Standard EN 7500.

New to the ZHU/zwicki-Line is an innovative fully automatic universal hardness testing system for both classical and instrumented testing, with high reproducibility and a wide range of applications – fully automatic Jominy tests are now also available.

Also new is the X-force load cell series, which scores with low sensitivity to parasitic influences such as transverse forces and bending moments, plus a large measurement range, high accuracy and self-identifying sensor plugs.
