This procedure provides the means for defining the magnitude and direction of cross curvature (an inherent property in thermostat metal).

1.1 This test method covers the determination of cross curvature of thermostat metals.

Note 1—This test method is not limited to thermostat metals and can be used for other materials for which the cross curvature must be measured accurately.

Note 2—This standard includes means for calculating cross curvature for widths other than that of the specimen having the same radius of curvature.

1.2 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of the inch-pound units may be approximate.

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 become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
