- ISO-12192 – Paper and board – Determination of compressive strength – Ring crush method: Ring Crush (RCT)
This standard was last reviewed and confirmed in 2017. Therefore this version remains current.
ISO 12192:2011 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.
ISO 12192:2011 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.
