Overview
IEC 60393-5:2015 is an international standard developed by the International Electrotechnical Commission (IEC) that defines the sectional specification for single-turn rotary low-power wirewound and non-wirewound potentiometers. These potentiometers are designed for use in electronic equipment and have a rated power dissipation of less than 10 watts. The standard outlines preferred ratings, characteristics, quality assessment procedures, tests, and measurement methods by selecting appropriate requirements from IEC 60393-1.
This edition includes significant updates such as revised assessment information for zero nonconforming levels (EZ and FZ) and a complete editorial revision. IEC 60393-5:2015 must be used alongside IEC 60393-1:2008 to ensure comprehensive compliance.
Key Topics
-
Scope and Application
Focus on single-turn rotary low-power wirewound and non-wirewound potentiometers used primarily in electronic devices with rated dissipation under 10 W.
-
Preferred Ratings and Characteristics

- Insulation resistance and torque requirements for starting and switching
- Nominal resistance values and tolerances
- Rated dissipation limits and voltage constraints
-
Quality Assessment Procedures
- Qualification approval through fixed sample size procedures
- Structurally similar component considerations
- Assessment levels EZ and FZ targeting zero nonconformity
- Lot-by-lot quality conformance inspection and periodic testing
-
Testing and Measurement Methods
- Environmental tests such as vibration, shock, and drying
- Sealing tests for container, shaft, and panel integrity
- Measurement of resistance law adherence and performance stability over time
-
Marking and Documentation
- Essential marking for components and packaging to facilitate traceability
- Detailed specifications including outline drawings, mounting, styles, and ordering information
Applications
The IEC 60393-5:2015 standard is essential for manufacturers, designers, and quality assurance professionals working with single-turn rotary potentiometers in electronic equipment. These components are widely used for:
- Volume and tone control in audio devices
- Position and level sensing in instrumentation
- Calibration and tuning in electronic circuits
- Low-power control applications where precise resistance adjustment is required
By adhering to this standard, organizations ensure product reliability, performance consistency, and international compliance, facilitating global market access.
