Usage: for determining bursting strength of paper and board and Linerboard
Standardization: TAPPI T 807, T 810, SCAN P-25, BS 3137, ISO 2759.
Device Description: the Burst Tester is built on a sturdy aluminum frame and the results are displayed on a digital load indicator. The
Burst tester works according to Mullen principle. A piston pumps glycerin under the circular elastic diaphragm. The diaphragm bulges
and distorts the sample, which is clamped around the periphery around the clamping bell. Pressure is increased until the sample is
burst.
Test Description: It is measured by giving a hydraulic pressure through a rubber diaphragm on a circular area of the specimen of CBF
under test conditions. Force requires to burst or complete rupture of the board is measured through a Digital Indicator. The bursting
strength value is expressed in terms of kg/cm2. The bursting strength defines the materials quality compare to the others. The value of
the bursting strength will give the indication that how much weight may be carried in the box/Paper.
