一、适用范围 本标准作为联邦德国工业标准1715第一部分的补充,规定了热双金属的检验方法。根据这个方法,厚度范围为0.3～1.25mm直条片状的热双金属,其测得的相对误差极限为±1％。(当厚度超出该范围时,误差极限将急剧增大)。 二、方法简述 根据图1所示,将厚度为S的热双金属条片放置在距离为L_M的两个支点上,在温差为t_2—t_1时测得其挠度A,即可计算得到 A scope of application This standard as a supplement to the first part of the Federal Republic of Germany Industry Standard 1715 provides for the test method of thermal bimetallic. According to this method, hot bimetal strip with a thickness in the range of 0.3-1.25 mm is measured with a relative error limit of ± 1%. (When the thickness is out of the range, the error limit will increase sharply). Second, a brief description of the method According to Figure 1, the thickness of the hot bimetal strip S placed on the distance L_M two fulcrum, the temperature difference t_2-t_1 when measured deflection A, can be calculated
