scope:

This part of IEC 60393 applies to single-turn rotary low-powerwirewound and non-wirewound potentiometers, with a rateddissipation less than to 10 W. These potentiometers are primarilyintended for use in electronic equipment. This part of IEC 60393prescribes preferred ratings and characteristics and selects fromIEC 60393-1, appropriate quality assessment procedures, tests andmeasuring methods. It provides general performance requirements forthis type of potentiometer. This standard gives the minimumperformance requirements and test severities.
