Describes a method for the determination of the edgewise compressive strength (ring crush resistance) of paper and paperboard, especially board used in the manufacture of fibreboard shipping containers.

This International Standard specifies a method for the determination of the edgewise compressive strength (ring crush resistance) of paper and paperboard, especially board used in the manufacture of fibreboard shipping containers.

This International Standard is applicable to all paper and paperboard with a thickness in the range 100µm to 580µm. For samples having a thickness below 280µm, test values can result from a combination of both buckling failure and pure compression.

NOTE For samples having a thickness exceeding 580µm, strain within the sample arising from bending the test piece into a cylinder might affect the test result (see References [6] and [7] in the Bibliography).
