Paper and board — Compressive strength — Ring crush method ISO 12192:2002

Publication date:   Nov 13, 2002

Scope

ISO 12192:2002 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 cartons and packing cases.
ISO 12192:2002 applies to all paper and paperboard with a thickness in the range of 280 micrometres to 580 micrometres. It may also be used for paper and board having a thickness less than 280 micrometres but those results are more a reflection of the paper's stiffness than its compressive strength. For paper and board having a thickness exceeding 580 micrometres, it may be impossible to bend them to the circumference without disturbing the structure.
