ML Burst Strength Tester

The procedure for determining burst pressure is different for paper and board. Therefore the ModularLine burst pressure device is also available in two variants. These are different, essentially, in the clamping bell and membrane designed for the procedure being used. The exact construction of the individual components as well as the high-precision measurement and regulation technology give the testing device a unique accuracy. As with all ModularLine testing devices, the burst test device can be used as either an independent laboratory device, and/ or as part of a ModularLine. In the standard configuration, the burst pressure is measured from the underside of the sample. According to requirements, a configuration is also available where the measurement is carried out at the upper surface.

Test Description

The sample for testing is placed in the measurement area. After pressing the start button the clamping bell travels down and fixes the sample. The glycerine, which is located below the membrane, is compressed and in this way the membrane is held continuously against the sample. This bulges, loses cohesion, and eventually bursts. Then the clamping bell travels back to the start position. The burst pressure measured and the energy absorption characteristics are displayed on the touch screen numerically and graphically. If more than one test is carried out, these can be compared statistically and standard deviation can be displayed.
