电子设备用电位器 第5部分:分规范:单圈旋转线绕和非线绕低功率电位器

[中文适用范围]： IEC 60393 的这一部分适用于额定功耗小于 10 W 的单圈旋转低功率线绕和非线绕电位器。这些电位器主要用于电子设备。 IEC 60393 的这一部分规定了首选额定值和特性，并从 IEC 60393-1、适当的质量评估程序、测试和测量方法中进行选择。它提供了此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格程度。 [外文原描述]： 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 .
