Utilizes biconical and log-periodic antennas to test the structural integrity of the shield.
The standard provides a harmonized procedure for measuring the shielding attenuation of anechoic chambers and shielded enclosures . This standard is critical for validating that a test environment is adequately isolated from external electromagnetic interference, which is essential for accurate EMC testing. Report Overview: EN 50147-1:1996 en 50147-1 pdf
Before formal validation, leakage tests are performed around critical "weak points" like door frames, air ducts, filters, and joints. Acceptance measurements are typically conducted before the installation of internal RF absorbers to ensure the base metallic structure is sound.
EN 50147-1 is part of a multi-part series that addresses different aspects of anechoic chamber validation. You can find the document at BSI Knowledge
If an EMC lab notices a sudden spike in ambient floor noise (e.g., seeing local FM radio stations appearing on their spectrum analyzer), they will reference the EN 50147-1 test procedures to systematically probe the chamber for leaks. Relationship with International Standards
Without the rigorous testing mandated by EN 50147-1, laboratories could not guarantee the validity of their EMC certifications. As wireless technology becomes more prevalent—with 5G and IoT devices filling the airwaves—the integrity of these shielded environments is more important than ever. The standard provides the mathematical and procedural framework to ensure that "quiet" really means quiet, allowing for the safe development of the technology we use every day. This standard is critical for validating that a
