IEC 60393-5:2015 applies to single-turn rotary low-power wirewound and non-wirewound potentiometers, with a rated dissipation less than to 10 W. These potentiometers are primarily intended for use in electronic equipment. This part of IEC 60393 prescribes preferred ratings and characteristics and selects from IEC 60393-1, 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.
