IEC 61000-4-3

IEC 61000-4-3 is an international standard that specifies how electronic devices should be tested to ensure they can operate properly in environments with radio frequency electromagnetic fields, such as wireless signals and radar. It sets out the testing methods and acceptable levels of interference that equipment must withstand without malfunctioning. This standard helps ensure that electronic products like smartphones, medical devices, and communication equipment are resistant to electromagnetic noise, maintaining performance and reliability in real-world electromagnetic environments.
