  • Ring Crush Test Determining the Ring Crush Strength

    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. The results of this test are highly dependent on proper specimen preparation.
