13 The burst test The Zwick Roell burst tester is an accessory of the testing machine for performance of the burst test (Fig.1). The testing machine takes over the functions of the hydraulic pump, the data acquisition and evaluation. This makes the burst test a program controlled test which assures correct test results with a minimum of manual operation. Fig. 2: Burst tester and pressure pre-selector unit When clamping a corrugated board specimen, it is important for the reproducibility of test results, to apply and maintain an accurate clamping force. For easy use, Zwick offers a pressure preselector,...
