Puncture Test/Bursting Strength on Tissue Paper

• The ball puncture test device is used to determine the resistance that a gripped specimen presents when penetrating a puncture body.
• The test fixture is designed for straightforward testing. The specimen is clamped horizontally between two plates, each of which has a circular aperture in the center.
• The sheet under test is simply laid on the lower plate and the machine is started.
• The specimen is automatically clamped and the test proceeds free from operator influence.
• A polished ball penetrates the center of the specimen at a constant rate.
• Using a 100 N load cell, even forces below 1 N can be recorded with the required accuracy. This allows reliable results to be obtained in research and development studies, with accurate recording of measured values far outside the usual range of 5 to 20 N.
• The maximum force (burst force) and the force with reference to the mass per unit area are measured.
• It is also possible, if relevant, to analyze the force deformation behavior, as deformation values are in principle also supplied by a testing machine .

Benefits:

• Clamping by means of spring force is fast and avoids operator error.
• The force-deformation behavior is shown as a curve, providing information regarding the ductility of tissue products.
• Simple assembly and wide measurement range allow tests to be performed on wet materials also.
• The surface consists of a Vulkolan coating.
