Smithers Pira measures the puncture resistance of paperboard and corrugated board using a Beach test. The puncture test determines the board’s resistance to penetration by sharp and solid objects.
A GE test apparatus with a moving pendulum that has a pyramid shaped puncture head is used. The results are given in Beach units (each unit is equal to 0.0299 joules).
Puncture testing is performed in accordance with BS4816, ISO 3036 and Tappi T803.
