Paper and board - Determination of compressive strength - Ring crush method
|Publication Date:||15 September 2011|
|ICS Code (Paper and board):||85.060|
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 μm to 580 μm. For samples having a thickness below 280 μm, test values can result from a combination of both buckling failure and pure compression.
NOTE For samples having a thickness exceeding 580 μm, strain within the sample arising from bending the test piece into a cylinder might affect the test result (see References  and  in the Bibliography).
