IEC 60717:2012适用于电子设备中使用的具有单向导线终端的电容器和电阻器。本标准提供了一种确定具有单向导线终端的电容器和电阻器所需空间的方法。注意:无需测量实际空间，只需确保组件适合其设计的最大空间即可。这可以通过固定量规来实现。与第一版相比的主要技术变化如下: -采用基于毫米的网格，IEC 60097中给出的优选网格系统， -仅使用国际单位制单位，导致从表1中删除英制尺寸， -图1中倒角深度的公差减小，以及 -引入相关规范中提供信息的要求。

IEC 60717:2012 applies to capacitors and resistors with unidirectional wire terminations intended for use in electronic equipment. This standard provides a method for determination of the space required by capacitors and resistors with unidirectional wire terminations. NOTE: Instead of measuring the actual space, it may be sufficient to ensure that a component fits into the maximum space for which it is designed. This may be achieved by means of fixed gauges. The main technical changes with respect to the first edition are the following:
- employment of the millimetre-based grid, the preferred grid system given in IEC 60097,
- employment of SI units only, causing deletion of the imperial dimensions from Table 1,
- reduction of the tolerance on the chamfer depth in Figure 1, and
- introduction of requirements on information to be given in a relevant specification.
