1.1 This test method covers the measurement of distortions in thin metal strip and the application of these measurements to an equation that will indicate the deviation from flatness.

1.2 The distortions to be measured in this test method are dish, wavy edges, buckle, longitudinal corrugation, and herringbone.

1.3 This test method is not intended to include the measurement of coil set or longitudinal curl, camber or edgewise curvature, or twist.

1.4 This test method is limited to metal strip 0.003 to 0.020 in. (0.08 to 0.50 mm) thick and not more than 6.0 in. (150.0 mm) wide.

1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are for information only.

1.6 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.
