The EN 50147-1 standard is a European technical specification focused on Anechoic Chambers, specifically regarding the measurement of shielding effectiveness.
It addresses different field types, including magnetic fields at lower frequencies and plane waves/microwaves at higher frequencies. BSI Knowledge Accessing the PDF
Keep in mind that EN 50147-1 is a technical standard, and understanding its requirements may require expertise in EMC and electrical engineering. If you're unsure about the standard or its application, consult with a qualified professional or contact the relevant authorities. en 50147-1 pdf
EN 50147-1 applies to all types of shielded enclosures, from small equipment rooms to large anechoic chambers. Its core technical specifications include:
Frequency Selection: Detailed lists of required test frequencies. The EN 50147-1 standard is a European technical
Operating Principle: A transmitter (TX) generates an RF signal outside the enclosure, while a receiver (RX) measures the signal level inside. The shielding attenuation is the ratio (in decibels) between the original signal strength and the reduced signal strength measured inside the enclosure.
While you might be tempted to find a free scanned copy of the en 50147-1 pdf, there are significant reasons to use the official version: If you're unsure about the standard or its
