Remember: a chamber that fails EN 50147-1 validation is a liability, not an asset. It can produce false passes (due to external noise masking real emissions) or false failures (due to ambient signals entering during immunity tests). By mastering this standard, you protect the integrity of every EMC measurement you will ever make.
If you are involved in electromagnetic compatibility (EMC) testing, radar cross-section (RCS) measurement, or wireless device certification, you have likely searched for the term . This search query is more than just a request for a document—it represents the need for clarity on how to validate one of the most expensive and sensitive pieces of test equipment in any lab: the anechoic chamber. en 50147-1 pdf
The reference measurement must be performed in a location with ambient noise at least 10 dB below the received signal. In dense urban environments, this is nearly impossible—hence many labs perform the reference measurement inside a larger shielded room or a TEM cell, which is a deviation allowed only with careful documentation.

Measurements in the low-frequency range focus on magnetic field attenuation.
The standard is the European benchmark for measuring the shielding attenuation of anechoic chambers and shielded enclosures. Published by CENELEC, it provides a rigorous, standardized procedure to verify that these rooms provide the electromagnetic isolation necessary for high-accuracy EMC testing . Scope and Applicability
