标准摘要
[中文适用范围]： 本部分 IEC 60393 适用于用于电子设备的螺杆操作式和旋转预设式电位器，包括线绕和非线绕类型。这些电位器主要用于需要对电路进行很少调整的调节目的。本部分 IEC 60393 规定了优选额定值和特性，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。它为这种类型的电位器提供了通用性能要求。本标准给出了该类型电位器的最低性能要求和测试严酷度。 [外文原描述]： 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 .
