Mullen burst tester carton bursting test

Mullen burst tester carton bursting test   INTRODUCTION: This is Mullen burst tester carton bursting test  . It is available to test a variety of materials,  such as paper,  paperboard,  textile. These models can also be fitted with a device to measure the deflection of the sample prior to burst. Paper digital bursting strength tester  has abundant functions,  such as,  parameter testing,  parametric transformation,  parameter adjusting,  parameter memory and parameter print. All are in accordance with related national standards. Paper digital bursting strength tester  has data processing function which can directly output result of data statistics with convenient operation,  easy regulation and stable performance.   PRINCIPLE: For Paper digital bursting strength tester  , a test sample is placed over a circular elastic diaphragm,  it is rigidly clamped at the periphery but free to bulge with the diaphragm. Hydraulic fluid is pumped at a constant rate,  and bulged the diaphragm until the test piece ruptures. The bursting strength of the test piece is the maximum value of the applied hydraulic pressure.   APPLICATIONS: Paper,  Foils,  Corrugated,  Textiles   STANDARDS: ISO 2758,  GB/T 454,  QB/T 1057    SPECIFICATIONS :
