ASTM B478-23

SIGNIFICANCE AND USE 4.1 This procedure provides a method for defining the magnitude and direction of cross curvature, an inherent property in thermostat metal. SCOPE 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 may 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 standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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 Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use. 1.4 This 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.
