Board bursting testers are specialized instruments used to measure the maximum pressure a board (such as corrugated, fiberboard, or other sheet-like materials) can withstand before failure. This article explains the purpose of these testers, their working principles, and what to consider when buying one. What Is a Board Bursting Tester? A board bursting tester (often known as a burst strength tester) is designed to evaluate the resistance of a board to rupture under increasing pressure. By applying a steadily increasing force—typically via a hydraulic or pneumatic system—the tester determines the point at which the board bursts. This measurement is essential for quality control, ensuring that boards used in packaging, construction, and other […]
