By using a tear test, this gives paper processors an estimated value of the future behavior of the end product (multi-layered carton, corrugated board). The tear test according to Elmendorf (ISO 1974 or TAPPI T 414), is used as the quality control criteria for the paper producer (final inspection) as well as for the processor (incoming goods quality control).
A tear test is performed in seconds therefore, the test data must be quickly acquired and evaluated.
The Elmendorf-Pendulum fulfills these requirements with a simple connection to a PC. Thus the raw data (energy values) can be converted into force values and then easily transferred to a QDA-System.
Empirical tests can be performed on a testing machine. Tensile grips or the
