Paper and board. Determination of compressive strength. Ring crush method Ingestion-build-132972 9 Group 2 tests1 Scope 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 100 m to 580 m. For samples having a thickness below 280 m, test values can result from a combination of both
