具有轴向引出端的圆柱形元件尺寸的测量

[中文适用范围]： 本国际标准适用于电子设备中使用的圆柱形电容器和电阻器。该标准给出了测量主体长度和检查延伸到带有轴向电线端子的组件的电线端子上的过度保护涂层的方法。它还提供了一种用于检查具有轴向电线端子的圆柱形部件的整体直径的方法。注：IEC 60717 中给出了具有单向端子的元件的测量方法。 [外文原描述]： IEC 60294:2012 applies to cylindrical capacitors and resistors for use in electronic equipment. This standard gives methods for measurement of the body length and for checking the excessive protective coating extending onto the wire terminations of components with axial wire terminations. It further provides a method for checking the overall body diameter of cylindrical components with axial wire terminations. NOTE: A measuring method for components with unidirectional terminations is given in IEC 60717. This second edition cancels and replaces the first edition, published in 1969, and constitutes a technical revision. The main technical changes with respect to the first edition are the following: - employment of SI units only, causing deletion of all imperial dimensions, - reduction of the tolerance on the chamfer depth in Figure 1 and Figure 2, - elaboration of the method for coating material extending onto wire terminations, - elaboration of the method for the overall body diameter, and - introduction of requirements on information to be given in a relevant specification.
