This standard specifies the method for determining the ring compressive strength of paper and paperboard using a compression tester. This standard is applicable to paper and cardboard with a thickness of 0.28 to 0.51 mm for cartons and cartons. It can also be used for paper and cardboard with a thickness as low as 0.15 mm and as high as 1.00 mm, but it indicates that the edge crush strength of the sample is less reliable.
