1.1 本规程涵盖了使用基于塞贝克效应的热电方法分拣材料的程序。该程序涉及使用直接和比较器型热电仪器来区分影响材料热电性能的材料变化。 1.2 虽然这种做法最常用于金属的分拣，但也可以应用于其他导电材料。 1.3 热电分选也可用于根据镀层厚度、镀层深度和硬度对材料进行分选。 1.4 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在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This practice covers the procedure for sorting materials using the thermoelectric method, which is based on the Seebeck effect. The procedure relates to the use of direct- and comparator-type thermoelectric instruments for distinguishing variations in materials which affect the thermoelectric properties of those materials. 1.2 While the practice is most commonly applied to the sorting of metals, it may be applied to other electrically conductive materials. 1.3 Thermoelectric sorting may also be applied to the sorting of materials on the basis of plating thickness, case depth, and hardness. 1.4 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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
