SRPS EN 60393-2:2017

Potentiometers for use in electronic equipment - Part 2: Sectional specification - Lead-screw actuated and rotary preset potentiometers

Scope

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.
