BBT - Ball Burst Tester
The burst resistance measurement (dry) determines the resistance of tissue paper against mechanical penetration by a spherical head.
Burst strength in accordance with DIN EN ISO 12625-9:2015-05.
The test piece is fixed between two concentric circular rings. The spherical head is fixed to the retaining arm and once the test is started moves downwards to the test piece at a defined speed until the test piece is punctured. The maximum force for this test is measured and displayed.
The tissue sheets require the following size: Ø 112.8 mm.
