q STANDARD TESTING MACHINES

Introduction The new technology utilised in this series of testing machines is based on the use of PC applications, which allow a totally new concept in steel testing. Gone are the old control consoles full of knobs and switches. Thanks to the use of the latest technology this new series provides both perfect closed loop hydraulic control and ergonomic operator usage. All the control functions are now managed from a standard keyboard and mouse. Our frames differ substantially from the old traditional models because of the originality of their design, new solutions employed and their extremely simple operation. The sophisticated software consists of a very complete suite of programs, not only for tension tests, but also flexure bending and compression on steel, and flexure and compression tests on concrete specimens, in compliance with the new EN specifications. Other accessories are available to test steel strands and electrowelded steel screen.

Extensometers used for measuring the extension of specimens in traction, particularly in the case of steel or brittle materials, are only able to detect strain during the first stage of the test, or rather, while the brittle materials conserve their elasticity as they have to be disconnected before failure. This simple and economic system, the result of our experience in this field, fully satisfies these requirements because: - it is applied directly to the specimen - it remains connected until breakage - it measures extension with high precision of both the elastic and plastic stage and with the appropriate simple adjustments, it is connectable to almost all testing machines - it avoids markings on the test pieces.
