3 Fig. 4: Hygienic articles give protection Fig. 3: Paper compounds in daily use Fig. 1: Paper as robust Fig. 2: Paper for technical uses packing Paper and paper materials Paper has accompanied man since ancient times (Fig. 1, page 2). Papyrus rolls show that man searched for, and found, a medium with which information could be stored and spread, while saving space and weight. This did not remain the only use. Books, and later industrial production of paper found new applications for this material. In the broadest sense, paper can be a structural material today, which carries and protects...

8 Scope of applications Materials testing machines are employed to determine the strength and deformation performance of specimen and components. These are stressed primarily with regard to tension, pressure, and deflection but also shear and torsion. These testing machines are characterized by large testing travel, high testing speed ranges, exchangeable measurement heads, and testing tools. This allows specimens and components of various shapes and dimensions and made from diverse materials and material combinations and accordingly different characteristics to be tested (Fig. 1). Most of...

This allows comfortably seated operation with sufficient legroom so that the system is also suited for wheelchair users. The Floor testing machines achieve a high accuracy from hard chromium-plated guide columns and a precision ball-type linear drive with play-free spindle nuts. Zwick offers...

11 Zwick Roell test software testXpert® II - Intelligent and Reliable, The New Software Generation for Materials Testing Zwick Roell has set the standard with testXpert® for intelligent materials testing software. Unlike other software, Zwick has standardized on testXpert® for all of its applications, both static and dynamic tests meaning you spend less time learning software and more time conducting tests. With testXpert® II, you benefit from over 80 years of testing experience and from over 10,000 successful installations worldwide. Some of the significant benefits of testXpert® II...

12 Screenshot of the graphical sequence editor Screenshot of testXpert® II Lims Synchronized video system in testXpert® II You can record the test procedure with a video camera or an USB webcam. testXpert® II saves the recorded images synchronized with the measuring data. The visual recording shows, for example, when, how and where the specimen necks, buckles or changes color. The alterations in specimen dimensions can be measured exactly from the captured images. In addition, before the test you can determine which events images should be recorded, for example the point in a cycle when...

13 The burst test The Zwick Roell burst tester is an accessory of the testing machine for performance of the burst test (Fig.1). The testing machine takes over the functions of the hydraulic pump, the data acquisition and evaluation. This makes the burst test a program controlled test which assures correct test results with a minimum of manual operation. Fig. 2: Burst tester and pressure pre-selector unit When clamping a corrugated board specimen, it is important for the reproducibility of test results, to apply and maintain an accurate clamping force. For easy use, Zwick offers a pressure...
