1.1 这些测试方法涵盖了恒温器金属柔韧性（热挠曲率或挠曲温度特性的量度）的测定。 1.1.1 试验方法A- 以0.015英寸扁平条的形式进行测试。（0.38毫米）或以上的厚度。 1.1.2 试验方法B- 以小于0.012英寸的螺旋线圈形式进行测试。厚度。 1.2 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对SI单位的数学转换，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性问题（如果有）。本标准的使用者有责任熟悉所有危害，包括制造商提供的本产品/材料的适当材料安全数据表（MSDS）中确定的危害，建立适当的安全、健康和环境实践，并确定应用使用前监管限制的能力。 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 这些测试方法用于确定恒温器金属对温度变化的响应或柔性。柔度由温度、试样尺寸和试样的相对运动计算。简单梁法（方法A）是认证的方法。螺旋线圈法（方法B）的任何使用应由用户和供应商共同商定。

1.1 These test methods cover the determination of flexivity (a measure of thermal deflection rate or deflection temperature characteristics) of thermostat metals. 1.1.1 Test Method A— Tested in the form of flat strip 0.015 in. (0.38 mm) or over in thickness. 1.1.2 Test Method B— Tested in the form of spiral coils less than 0.012 in. in thickness. 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 Material Safety Data Sheet (MSDS) 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 These test methods are used for determining response to temperature change or flexivity of thermostat metal. The flexivity is calculated from the temperatures, dimensions of specimen, and the relative movement of the specimen. The simple beam method (Method A) is the method for certification. Any use of the spiral coil method (Method B) is to be mutually agreed upon between the user and supplier.
