1.1 本试验方法适用于恒温器金属横曲率的测定。 注1: 该试验方法不限于恒温器金属，也可用于必须准确测量横曲率的其他材料。 注2: 本标准包括计算宽度不同于具有相同曲率半径的试样的横向曲率的方法。 1.2 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任熟悉所有危险，包括制造商提供的本产品/材料的适当安全数据表（SDS）中确定的危险，制定适当的安全、健康和环境实践，并在使用前确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 该程序提供了一种定义横曲率大小和方向的方法，横曲率是恒温器金属的固有特性。

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. ====== 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.
