What is IEC 60320-2-2: 2019 ?

IEC 60320-2-2: 2019 is an essential international standard that outlines the safety requirements for appliance couplers used in electronic equipment. It is published by the International Electrotechnical Commission (IEC) and serves as a technical document that sets the design, construction, and testing requirements for appliance couplers. The main objective of IEC 60320-2-2: 2019 is to minimize the risks of electric shock, fire, and other hazards associated with improper connections or faulty couplers.

Key Requirements of IEC 60320-2-2: 2019

IEC 60320-2-2: 2019 has several key requirements that are essential for ensuring safety, compatibility, and reliability in various technical applications. These requirements include:

Electrical Safety: The standard specifies the maximum allowable voltage and current ratings for the appliance coupler, as well as the use of fuses or circuit breakers to protect against overheating and electrical hazards.

Contact Element: The standard requires the appliance coupler to have a contact element that is accessible to the user, ensuring ease of and maintenance.

Ground Plug: The standard specifies the requirement for a grounding plug that is easily accessible and provides a return path for the electrical current.

Mounting: The standard outlines the mounting requirements for the appliance coupler, including the use of threaded inserts or mounts that provide a secure connection.

Operating Temperature: The standard sets the maximum allowable operating temperature for the appliance coupler, ensuring that it can withstand the temperature variations in an environment without affecting its performance.

Static Discharge: The standard specifies the amount of static discharge that can occur from the appliance coupler, which is a measure of its ability to withstand electrical noise and spikes.

Vibration: The standard outlines the vibration requirements for the appliance coupler, ensuring that it can withstand the mechanical vibrations without affecting its performance.

Radio Frequency Interference (RFI): The standard requires the appliance coupler to have an adequate barrier filter to prevent interference from other radio frequencies, which may interfere with the device's operation.

Conclusion

IEC 60320-2-2: 2019 is an essential international standard that outlines the safety requirements for appliance couplers used in electronic equipment. By ensuring the safety, compatibility, and reliability of the appliance coupler, IEC 60320-2-2: 2019 plays a significant role in protecting people from electrical hazards and ensuring the safety of various technical applications.
