ASTM B 754 : 2022 : REDLINE

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

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

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

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

1.5Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard.

1.6The following safety hazard caveat pertains only to the test method(s) described in this test method:

1.7This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
