Board Puncture Strength Tester measures the energy required to puncture board with a pyramidal head affixed to a pendulum arm. These energy includes the energy to tear the material and the energy to bend it out of the way of the point.
Board Puncture Strength Tester Principle:
A puncture head, consisting of a stainless steel right-angled triangular pyramid is attached to a solid arm. The arm, under load, swings through an arc until it contacts the specimen clamped between two horizontal plates. The upper plate is fixed; the lower is spring loaded. Each has a triangular hole to accommodate the puncture head.
A collar, loosely fitted to the cylindrical extension to the puncture head, detaches after penetration and adheres to the specimen, keeping the hole open and preventing and braking action on the pendulum.
