IEC 60393-1:2008适用于电子设备中使用的所有类型的电阻电位计，包括丝杠驱动型、预置型、多匝单元等。它规定了用于质量评估或任何其他目的的电子元件的章节和详细规范的标准条款、检验程序和测试方法。它主要是为了符合广泛使用的带操作轴的单圈旋转电位计而编写的，并描述了测试方法。与前一版本相比，本版本包含以下重大技术更改:实施附录H，取代前一版本的第3节。它还包括与表格、图表和参考资料有关的小修订。

IEC 60393-1:2008 is applicable to all types of resistive potentiometers, including lead- screw actuated types, presets, multi-turn units, etc., to be used in electronic equipment. It establishes standard terms, inspection procedures and methods of test for use in sectional and detail specifications of electronic components for quality assessment or any other purpose. It has been mainly written, and the test methods described, to conform to the widely used single-turn rotary potentiometer with an operating shaft. This edition contains the following significant technical changes with respect to the previous edition: implementation of Annex H which replaces Section 3 of the previous edition. It also includes minor revisions related to tables, figures and references.
