IEC 61000-4-21: “Testing and measurement techniques–Reverberation chamber test methods”

IEC 61000-4-21 aims to standardize radiated testing (both emissions and immunity/susceptibility) in reverb chambers. This includes testing for shielding effectiveness.

CISPR 25: “Vehicles, boats and internal combustion engines - Radio disturbance characteristics - Limits and methods of measurement for the protection of on-board receivers”

CISPR 25 is an automotive standard that covers the main emissions testing methods needed to ensure self-compatibility between a vehicle and its own on-board receivers..

ANSI C63.4: “American National Standard for Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz”

ANSI C63.4 contains the main test methods used to verify compliance to FCC Part 15 unintentional emissions limits, making it key for consumer electronics.

MIL-STD-461: “Requirements for the Control of Electromagnetic Interference Characteristics of Subsystems and Equipment”

MIL-STD-461 is one of the core EMC standards, having evolved with military applications since WWII. It is widely used in the aerospace and defense sectors.
