is more than just a technical document—it is the essential European Standard that defines how to accurately measure the shielding attenuation of anechoic chambers and screened rooms. This article explores the standard's origins, technical content, real-world applications, and how to legally obtain the PDF. It is a critical guide for engineers, EMC test professionals, and anyone involved in building or certifying a shielded enclosure.
The procedure involves measuring the signal level transmitted through the shield over a frequency range (typically 10 kHz to 40 GHz) and calculating the difference from a reference calibration.
EN 50147-1 is a European standard, often available in PDF, defining procedures for measuring the shielding effectiveness of enclosures like anechoic chambers across a 9 kHz to 40 GHz range. It outlines magnetic, electric, and plane wave test methods to validate shielding integrity, typically performed before installing internal absorbent materials.

EN 50147-1:1996 (still the current active version) specifies a procedure for measuring the shielding attenuation of an anechoic chamber—typically a fully or semi-anechoic chamber used for EMC testing. The frequency range covered is generally from 10 kHz to 18 GHz, although practical applications often extend to 40 GHz with appropriate equipment.

The search results yielded several hits, but Emily was cautious, knowing that she needed to download the official document to ensure accuracy. After a few clicks, she landed on the official CENELEC (Comité Européen de Normalisation Électrotechnique) website, which offered the EN 50147-1 standard for download in PDF format.
Precise antenna alignment and distance measurements are critical; even small misalignments can create the illusion of higher attenuation. Related Technical Guidance Shielding Effectiveness Test Guide - A.H. Systems
