标准范围

IEC 60393-2:20 15适用于电子设备中使用的丝杠驱动和旋转预设电位计，线绕和非线绕。这些电位计主要用于需要不经常调整的微调电路。IEC 60393的这一部分规定了优选的额定值和特性，并从IEC 60393-1中选择了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 60393-2:2015 applies to lead-screw actuated and rotary preset potentiometers, wirewound and non-wirewound for use in electronic equipment. These potentiometers are primarily intended for use in circuits for trimming purposes which require infrequent adjustments.This part of IEC 60393 prescribes preferred ratings and characteristics and selects from IEC 60393-1 the 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.
