IEC 60393-3:2023 PDF

Scope: IEC 60393-3:2023 applies to rotary precision potentiometers for use in electronic equipment. The object of this document is to prescribe preferred ratings and characteristics and to select from IEC 60393-1, the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of potentiometer. This document gives the minimum performance requirements and test severities.
This edition includes the following significant technical changes with respect to the previous edition:
a) revised all parts of the document based on the ISO/IEC Directives, Part 2:2018 (eighth edition) and harmonized with other similar kinds of documents;
b) the document structure has been organized to follow new sectional specification structure decided in TC 40;
c) revision of the information on the assessment level EZ (zero nonconforming).
