IEC 61000-4-24:2015-AMD1:2018 is a technical standard that addresses the immunity requirements for electromagnetic compatibility (EMC) in electrical and electronic equipment against radio frequency (RF) disturbances when exposed to conducted and radiated disturbances in the frequency range of 9 kHz to 400 GHz. This standard provides guidelines for testing and evaluating the performance of equipment in different environments and ensures their proper functioning in the presence of RF disturbances.
Understanding EMC Immunity Requirements
Electrical and electronic equipment are becoming increasingly susceptible to RF disturbances due to the rising number of wireless communication devices and industrial equipment. As a result, these devices may experience operational issues or even fail when exposed to RF disturbances such as electromagnetic fields generated by other nearby devices or external sources like lightning strikes. To prevent such malfunctions, standards like IEC 61000-4-24:2015-AMD1:2018 have been developed to impose specific immunity requirements that equipment should meet to ensure their reliability and performance in the presence of RF disturbances.
Testing Methodologies
The standard specifies various test methods and procedures to evaluate the equipment's immunity against RF disturbances. These tests include assessing the equipment's resilience to conducted and radiated disturbances by subjecting them to specified levels of electromagnetic fields. Conducted disturbances are injected directly into the equipment through its power supply lines, while radiated disturbances are applied using antennas positioned at predefined distances from the equipment. The performance of the equipment is then evaluated based on criteria defined in the standard, ensuring that the device remains functional and operates within acceptable limits during and after exposure to RF disturbances.
Benefits and Significance
IEC 61000-4-24:2015-AMD1:2018 provides numerous benefits for manufacturers and end-users of electrical and electronic equipment. For manufacturers, compliance with this standard assures their products' reliability and immunity against RF disturbances, enhancing the market reputation and customer trust in their offerings. It also allows manufacturers to demonstrate legal compliance with international electromagnetic compatibility regulations. For end-users, adherence to this standard ensures that the purchased equipment will perform as intended even in the presence of RF disturbances, minimizing potential operational disruptions and improving overall system performance and safety.
