Abstract
A board testing apparatus and method and in particular a testing apparatus for testing a board made of a corrugated material, such as corrugated cardboard, for failure characteristics. The method comprises taking a corrugated board from a corrugator or converter, locating at least a part of the board into a testing machine, performing a non-destructive compression test on a sample region of the part of the board within the machine and providing a compression test characteristic reading of that region of the board, comparing that characteristic reading against a predefined acceptable compression test characteristic reading that design of corrugated board should have and concluding from the comparison as to whether the board, or that sample region of the board, meets a required compression stiffness parameter.
