Friction testing device RPG DIN EN ISO 8295

Characteristics

  • Determining the friction coefficents of synthetic materials / sheets / films.

The device is used for testing the friction behavior of two materials which are moved relatively to each other. The testing can be executed according to DIN EN ISO 8295 (Plastics Film and Sheeting - Coefficient of Friction) and mainly serves for quality control. In the test the lower specimen is fixed to the measuring slide - when testing against metal, a metal plate is attached to the slide. The holding mechanism, which is connected to the dynanometer by a spring, holds the upper specimen. A weight which is given by the according testing standard, provides the surface pressure between the friction materials. During the test the measuring slide is moved against the friction resistance with a defined skipping speed (100mm/min) and the dynamometer registers the value of the produced friction force. The measuring distance is ca. 60 mm. Before the test the skipping speed can be set by the software. Possible speeds are from 5 to 300 mm/min. The friction testing device is equipped with a 20 N friction force sensor which is connected to a computer via a measuring amplifier and a USB-interface. The software works together with a USB measuring module which has a resolution of 14 Bit. The measuring slide can be equipped with a heating panel which is attached from below. The temperature of the measuring slide can then be raised to max. 80°C.
