The International Electrotechnical Commission (IEC) has issued standard IEC 60393-3:2023 "Potentiometers for use in electronic equipment - Part 3: Sectional specification: Rotary precision potentiometers".

On August 18, 2023, the International Electrotechnical Commission (IEC) issued standard IEC 60393-3:2023 "Potentiometers for use in electronic equipment - Part 3: Sectional specification: Rotary precision potentiometers".


The IEC 60393-3:2023 standard is applicable to rotary precision potentiometers used in electronic equipment. The purpose of this standard is to specify the priority ratings and characteristics of such potentiometers, and to select applicable quality assessment procedures, testing and measurement methods from the IEC 60393-1 standard, as well as to specify the general performance requirements, minimum performance requirements, and test severity levels for such potentiometers.


Compared to the old version of the standard IEC 60393-3:1992, this new version includes the following major technical changes:

(1) Revised all parts of the standard document in accordance with ISO/IEC Guidelines Part 2 (8th Edition 2018) and coordinated with other similar documents;

(2) The arrangement of the file structure has followed the new sub standard structure determined by TC 40;

(3) Revise the information regarding the evaluation level EZ (zero non conformities).
