Tested at high frequencies (100 MHz to 1 GHz) using log-periodic antennas.

EN 50147-1 has been as identical national standards in many European countries. These include:

The standard clearly defines which types of enclosures it applies to—typically, welded or modular shielded rooms and anechoic chambers used for EMC testing. It does not apply to small shielded enclosures like those for individual electronic components. en 50147-1 pdf

Understanding EN 50147-1: The Standard for Anechoic Chambers

This article is for informational purposes. Always refer to the official EN 50147-1 PDF for definitive requirements. Standards are subject to update; verify the current version before use. Tested at high frequencies (100 MHz to 1

1 GHz to 40 GHz (depending on the intended use of the chamber) 2. Test Setup and Equipment

Standards evolve. The official PDF ensures you are using the exact version required by your Notified Body or customer contract. It does not apply to small shielded enclosures

The standard establishes a common measurement procedure for validation, applicable to any shielded chamber or room. It is designed to ensure consistency in testing, regardless of the test lab or equipment manufacturer. EN 50147-1 is primarily for final validation after a chamber is built, not for ongoing monitoring (which may be covered by other documents like ).

The reference level establishes the baseline measurement against which attenuation is calculated, typically involving a calibration measurement in an open, unobstructed environment.
