The Ring/Edge/Flat Crush Tester is commonly used in the paper and packaging industry to evaluate the strength of the corrugated boards and other paper-based materials used in products such as boxes, cartons, and other similar items. It's an important quality control step in the production process to ensure that the materials are strong enough to protect the contents inside them and meet industry standards for strength and durability.

A Ring/Edge/Flat Crush Tester is a tool used to measure the compressive strength of the corrugated board and other paper-based materials. The tester typically consists of a compression platen, a load cell or force sensor, and a digital readout or indicator that displays the compressive strength measurement.It is based on standard IS 7063-2.
