IEC 60393-5:20 15适用于额定耗散小于10 W的单匝旋转低功率线绕和非线绕电位计。这些电位计主要用于电子设备。IEC 60393的这一部分规定了优选的额定值和特性，并从IEC 60393-1中选择适当的质量评估程序、测试和测量方法。它提供了这类电位器的一般性能要求。该标准给出了最低性能要求和测试严重性。与上一版相比，此版本包括以下重大技术变更: a)修订关于评估级别EZ和FZ（零不合格）的信息； b)完成编辑修订。 本出版物应与IEC 60393-1:20 08一起阅读。

IEC 60393-5:2015 applies to single-turn rotary low-power wirewound and non-wirewound potentiometers, with a rated dissipation less than to 10 W. These potentiometers are primarily intended for use in electronic equipment. This part of IEC 60393 prescribes preferred ratings and characteristics and selects from IEC 60393-1, appropriate quality assessment procedures, tests and measuring methods. It provides general performance requirements for this type of potentiometer. This standard gives the minimum performance requirements and test severities. This edition includes the following significant technical changes with respect to the previous edition:
a) revision of the information on the assessment level EZ and FZ (zero nonconforming);
b) complete editorial revision.

This publication is to be read in conjunction with IEC 60393-1:2008.
