Scope

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.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Significance and Use

This test method is intended for use in measuring the two principle dimensions, length and width, of paper sheets. Accurate, reproducible sheet dimensions are required for successful passage of paper sheets through printing or copying machines.

In addition to sheet dimensions, sheet squareness measurements may also be made.

While not specifically described in this test method, the equipment and techniques described herein may be extended to other uses, such as the measurement of location and reproducibility of punched holes in sheets of paper.

This test method is intended for use in measuring conformity of sheet size as stated in standard specifications of materials, such as cut-sized papers.
