The Burst Test Explained
To measure bursting strength the specimen is gripped securely between two clamping rings. Once a corrugated board specimen is clamped it is essential to maintain the gripping force to ensure reproducible test results. Particular attention must be paid to the dynamics of the testing equipment. As a burst test is performed within a few seconds and the maximum pressure must be determined with absolute precision, the measurement speed of the testing instruments must be correspondingly high. If results are to be compared between different laboratories, the measurement speeds of the instruments must be identical. A constant volume-flow must also be maintained during the test with a high degree of accuracy.
