What is BS EN 61000-4-22 - Electromagnetic compatibility about?
BS EN 61000 is a series on Electromagnetic compatibility (EMC). Electromagnetic compatibility is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI) or even physical damage in operational equipment. BS EN 61000-4-22 considers immunity tests and emission measurements for electric and/or electronic equipment. Only radiated phenomena are considered. It establishes the required test procedures for using fully anechoic rooms for performing radiated immunity testing and radiated emission measurements.
BS EN 61000-4-22 establishes a common validation procedure, equipment under test (EUT) set-up requirements, and measurement methods for fully anechoic rooms (FARs) when both radiated electromagnetic emission measurements and radiated electromagnetic immunity tests will be performed in the same FAR. BS EN 61000-4-22 main goal is to provide general measurement procedures to all concerned product committees of IEC or CISPR. Specific product requirements and test conditions are defined by the responsible product committees. The methods described in As a basic measurement standard, BS EN 61000-4-22 does not intend to specify the test levels or emission limits to be applied to a particular apparatus or system(s) are appropriate for radiated emission measurements and immunity tests in the frequency range of 30 MHz to 18 GHz.

Why should you use BS EN 61000-4-22 - Electromagnetic compatibility?
The goal of Electromagnetic compatibility is the correct operation of different equipment in a common electromagnetic environment. It is also the name given to the associated branch of electrical engineering. BS EN 61000-4-22 establishes the required test procedures for using fully anechoic rooms for performing radiated immunity testing and radiated emission measurements. The main text of BS EN 61000-4-22 provides all information that is common to both radiated emission measurements and immunity tests in a FAR (fully anechoic room). BS EN 61000-4-22 includes the description of a FAR, a common set-up for equipment under test (EUT), and a harmonized validation/calibration procedure.
The test methods described in BS EN 61000-4-22 are based on the harmonized validation/calibration which verifies a fully anechoic room as a measurement system, including the room, antenna, and associated cables simultaneously. The validation procedure determines a combined transducer factor for a fully anechoic room measurement system that is later applied to both emission measurements and immunity tests. If different sets of antennas and/or cables are used for emission measurements and immunity tests the validation/calibration process is performed twice. BS EN 61000-4-22 provides the measurement procedure and any special considerations for performing radiated immunity tests and the measurement procedure and any special considerations for performing radiated emission measurements. BS EN 61000-4-22 also provides background on the system transducer factor and simultaneous emissions/immunity validation method and guidance for the calculation of the uncertainty of measurement results obtained using a fully anechoic room and instrumentation in accordance with ISO/IEC Guide 98-3 [4]1). Using BS EN 61000-4-22:2011 you can establish a common validation procedure, equipment under test (EUT) set-up requirements, and measurement methods for fully anechoic rooms when both radiated electromagnetic emission measurements and radiated electromagnetic immunity tests will be performed in the same fully anechoic rooms.
