ISO 2758 Automatic Bursting Strength Tester for Paper Bursting Strength Determination

Bursting Strength Tester

Application

Bursting Strength refers to the ability of paper and paperboard materials to withstand bursting or breaking when subjected to external forces, typically measured using a bursting strength tester. The result indicates the maximum force that the paper or paperboard can resist per unit area before rupturing, providing insights into the material's structural strength and durability, particularly relevant in the context of packaging and transportation.

Bursting strength testing is essential for evaluating the structural integrity and durability of paper and board, particularly in the context of packaging and transportation. This test ensures that the chosen paper materials for packaging can withstand external pressures, minimizing the risks of damage or breakage during transit and handling. Regular testing serves as a crucial quality control measure for manufacturers, allowing them to maintain consistent production standards and promptly address any issues. The results provide valuable insights into the selection of appropriate paper and board materials for packaging design.

Board Bursting Tester

BNP-01 Board Bursting Tester is used to measure the bursting strength of board submitted to increasing hydraulic pressure. It is applicable to all types of board (including corrugated and solid fiberboard) having bursting strengths within the range 350 kPa to 5 500 kPa, It is also applicable to papers or boards having bursting strengths as low as 250 kPa if the paper or board is to be used to prepare a material of higher bursting strength, such as corrugated board.

Board Bursting Test Standards:

GB 1539, GB 6545, ISO 2759, TAPPI T 810, TAPPI T 807，QB/T 1057

Paper Bursting Tester

ZNP-01 Paper Bursting Tester is used to measure the bursting strength of paper submitted to increasing hydraulic pressure. It is applicable to paper having bursting strengths within the range70 kPa to 1400 kPa. It is not intended to be used for the components (such as fluting medium or linerboard) of a combined board, for which the method given in ISO 27591 is more suitable.

Paper Bursting Test Standards:

GB/T 454, QB/T 1057, ISO 2758, TAPPI T 403, JIS P 8112, BS 3137, ASTM D774

Test Principle

A test piece, placed over a circular elastic diaphragm, is rigidly clamped at the periphery but free to bulge with the diaphragm. Hydraulic fluid is pumped at a constant rate, bulging the diaphragm until the test piece ruptures. The bursting strength of the test piece is the maximum value of the applied hydraulic pressure.
