    The horizontal Tensile Tester, model FRANK-PTI, has been developed especially for the paper industry. Designed to provide easy operation and precise measurement. Colour touchscreen displays values and graphs. Test methods are selectable from the main menu. The instrument measures according to relevant standards. Changing from MD to CD simply by one
    keystroke gives ratio calculations. A printer can be connected and prints single values as well as graphs and statistic.

    Test description

    You can select a test program (e.g. wet tensile test according to EN 12625-5)  with pre-selected parameters. The specimen is given an identification number. Before wet testing, check and if necessary fill the water inlet. The operator inserts the sample. The clamps detect the sample and close. They move towards each other and immerse the sample (depending on the preset time). After immersion time, the tensile process starts. The sample is tensioned until it breaks.

    Other programs (e.g. EN 12625-4, or ISO 1924-1, -2, or -3) immediately tension the sample. The touchscreen displays graphs and single values. The clamps return to their initial position and a new sample can be inserted and tested. By changing from MD to CD values are allocated and stored separately. The single curves can be viewed on the touchscreen. The statistics display gives the single values as well as the MD/CD ratio. Values
    and graphs can be printed or transferred to a PC.

    The clamps have been specially designed for paper testing. The clamps correspond exactly to the appropriate standards. The FRANK-PTI Tensile Tester also allows measurement according to the withdrawn standard 1924-1. Some clients had tested with 180 mm samples for decades. These samples can be still tested on our horizontal tensile tester.
