Title: Anechoic chambers — Part 1: Shield attenuation measurement en 50147-1 pdf

It specifies test methods for measuring the shielding effectiveness (attenuation) of anechoic chambers used for electromagnetic compatibility (EMC) testing — typically for radiated emissions and immunity measurements. The standard is designed specifically for road vehicles

This is the section most users search for. The standard outlines two primary methods: including the battery cells

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.
