EN 50147-2 addressed the suitability of alternative test sites regarding site attenuation, and applied to radiated emission measurements above 30 MHz conducted according to CISPR 16-1. The document was withdrawn in 2007, and its requirements are now incorporated into newer CISPR standards.

EN 50147-1 is part of a multi-series European standard dedicated to anechoic chambers. Specifically, Part 1 focuses on the of the chamber's metallic enclosure. Before any RF-absorbing materials are installed inside a room, the outer shield must prove it can block external electromagnetic fields. The Scope of the Standard

The EN 50147 series outlines the performance criteria and verification steps for full and semi-anechoic chambers. Part 1 specifically focuses on . en 50147-1 pdf

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.

EN 50147-1 contributes to the "presumption of conformance" for CE marking under relevant EU Directives. EN 50147-2 addressed the suitability of alternative test

The primary goal of an EN 50147-1 test is to determine how well an enclosure blocks electromagnetic energy. This is critical for two main reasons:

Building or maintaining an EMC facility requires precision. Relying on an unverified chamber can lead to false test failures or, worse, undetected compliance issues in your products. Specifically, Part 1 focuses on the of the

The knife-edges and beryllium-copper fingerstock gaskets must be checked. They wear down over time.
