Standard Test Method for Mechanical Torque Rate of Spiral Coils of Thermostat Metal 温控金属螺旋线圈机械扭矩的标准测试方法
发布日期: 2020-10-01
1.1 本试验方法涵盖了确定恒温器金属螺旋线圈机械扭矩率的原理。 注1: 本试验方法专门用于测定化油器和歧管热控制用恒温器金属制成的螺旋线圈的机械扭矩率。该方法不仅限于恒温器金属,还可用于其他材料的螺旋线圈,必须准确测量其扭矩率。 1.2 以英寸-磅为单位的数值应视为标准值。英寸-磅单位的公制等价物可能是近似值。 1.3 本标准并非旨在解决与其使用相关的所有安全问题(如有)。本标准的用户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,建立适当的安全、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(TBT)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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 该试验方法有助于确定恒温器金属螺旋线圈的机械力。 4.2 线圈的机械性能可能因恒温器金属材料的批次而异。该方法可用于确定给定机械扭矩规格下材料的最佳厚度和长度。 4.3 该测试可用作质量测试,以确定许多恒温器金属线圈的验收或拒收。
1.1 The test method covers the principles of determining the mechanical torque rate of spiral coils of thermostat metal. Note 1: This test method has been developed particularly to cover the determination of the mechanical torque rate of spiral coils made of thermostat metal for carburetors and manifold heat controls. The method is not limited to thermostat metals and can be used for spiral coils of other materials for which the torque rate must be measured accurately. 1.2 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of 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 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 test method is useful to determine the mechanical force of spiral coils of thermostat metal. 4.2 The mechanical properties of a coil may vary from lot to lot of thermostat metal material. This method is useful for determining the optimum thickness and length of the material for a given mechanical torque specification. 4.3 This test is useful as a quality test to determine acceptance or rejection of a lot of thermostat metal coils.
