              The TAPPI T826 test method is widely used for evaluating the short span compressive strength of paper and board materials, especially those used in container and box manufacturing. The test provides valuable information about the intrinsic compression performance of paper fibers by measuring the maximum compressive force a small test span can withstand before failure.
