Ring Crush Test Determining the Ring Crush Strength

This test is performed according to ISO 12192 and TAPPI T 822. The ring crush test is similar to the short-span compression test in that the strength of the liner or fluting is measured both in the machine direction and perpendicular to it. It is important that force application to the specimen is exactly perpendicular during these tests.
