The Mullen Type Bursting Strength Testers, Models HT8020A and HT8320A, are designed to measure the maximum bursting strength of paper and paper products having a bursting strength of 50 kPa up to 1200 kPa (7 psi up to 175 psi) in the form of flat sheets of up to 0.6 mm (0.025 in.) in thickness as described in TAPPI T 403 om-02 “Bursting Strength of Paper”.
These models may also be used to determine the bursting strength of paper and paper products occurring as single or laminated flat sheets not over 0.6 mm (0.025 in) in thickness having a bursting strength of 30 kPa up to 1400 kPa (4 psi up to 200 psi) as described in ASTM D774/D774M “Standard Test Method for Bursting Strength of Paper” as well as ISO 2758 “Paper – Determination of Bursting Strength”.
The Mullen Type Bursting Strength Testers, Models HT8020B, HT8320 and HT8321, may also be used in testing corrugated, fiberboard and linerboard as described in TAPPI T 807 om-03 “Bursting Strength of Paperboard and Linerboard”.
Additionally, the Models HT8020B, HT8320 and HT8321 may be used for testing corrugated and solid fiberboard as described in TAPPI T 810 om-06 “Bursting Strength of Corrugated and Solid Fiberboard”.
