1.1 This test method determines the average length, width, and squareness of sheets of paper. It may also be used to determine the difference between consecutive sheets in a lot of paper. It is especially useful with printing and writing papers which have been cut to specific sizes. The procedure is applicable to a wide range of sheet dimensions, including dimensions as small as 1.6 in. (41 mm) to as large as 60.2 in. (1530 mm). While not the subject of this test method, the equipment described may be used to determine uniformity of hole punching and various process variables related to the cutting of sheeting papers.
