Description

Digital burst tester, working according to Mullen: A plunger pushes glycerin against the membrane in order to bulge it. The distended membrane imposes pressure upon the sample (which is clamped over the membrane by means of a clamping bell). Pressure is increased until the sample bursts. The sample is clamped pneumatically. The device is equipped with safety protection. Results are displayed digitally. The maximum sample thickness is 12 mm.

Test description

The sample is placed between clamping bell and membrane. After pushing the start button, the sample holder lowers and clamps the sample. A piston pumps glycerin at a constant rate under the membrane. The sample is bulged until it bursts. The burst value is displayed. As soon as the sample bursts, the burst value is displayed. The plunger returns to its initial position, and the sample is released. The instrument is ready for further measurements. Besides single values, the menu shows statistic values (min, max, average, and standard deviation). The values can be processed by means of Probe Net or printed out.
