What is BS EN 60393-5 –low-power wire wound and non-wire wound Potentiometers about?  
BS EN 60393-5 is an international standard that discusses potentiometers for use in electronic equipment.
BS EN 60393-5 is the fifth part of multi-sereis. BS EN 60393-5 applies to single-turn rotary low-power wirewound and non-wire wound potentiometers, with a rated dissipation of less than 10 W. These potentiometers are primarily intended for use in electronic equipment.
Who is BS EN 60393-5 – low-power wire wound and non-wire wound Potentiometers for? 
BS EN 60393-5 on potentiometers for use in electronic equipment is relevant to: 
- Manufacturers of electronic equipment
- Potentiometers industry
- Electronics industry
Why should you use BS EN 60393-5 – low-power wire wound and non-wire wound Potentiometers?  
A position sensor is a sort of potentiometer. They're used to determine how far something has moved in any direction. Rotary potentiometers measure rotational displacement whereas linear potentiometers measure linear displacement.
BS EN 60393-5 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.
BS EN 60393-5 gives the minimum performance requirements and test severities.
The ability to operate within specified limits of temperature, pressure, humidity, mechanical endurance tests, or other environmental conditions and combinations of these conditions
The test conditions are outlined in BS EN 60393-5, and the fixed sample size test schedule's performance criteria are identical to those outlined in the detailed specification for quality conformity inspection. To assess the quality or useful life of a given production lot, the test methods should be applied in accordance with a suitable sampling plan and may be supplemented by appropriate additional tests, if necessary.
Thus, BS EN 60393-5 helps you to controls electrical devices such as volume controls on audio equipment. This can enable you to measure voltage properly and achieve variable voltage from a fixed-voltage source.
