Not directly. EN 50147-1 applies to complete enclosures, not sheet materials. For materials testing, refer to ASTM D4935 or IEEE 299. en 50147-1 pdf

Understanding EN 50147-1: The Standard for Anechoic Chamber Shielding Effectiveness

The shielding effectiveness (SE) is calculated in decibels (dB) using the following formula: The standard is organized into logical sections that

Relevant for industries including telecommunications, aerospace, medical, and defense. iTeh Standards Key Measurement Principles

As (dB)=20log10(VrefVshield)A sub s (dB) equals 20 log base 10 of open paren the fraction with numerator cap V sub r e f end-sub and denominator cap V sub s h i e l d end-sub end-fraction close paren Prefcap P sub r e f end-sub is the reference power level, and Pshieldcap P sub s h i e l d end-sub is the received power through the shield. Critical Test Points Within An Enclosure EN 50147-1:1996 - Shield attenuation measurement For materials testing, refer to ASTM D4935 or IEEE 299

The primary objective of the standard is to provide a reproducible, reliable, and standardized procedure to verify that a chamber can successfully attenuate external electromagnetic fields across a broad frequency spectrum. The EN 50147 Series Structure

Accessing the full document is essential for laboratories seeking accreditation. It provides the technical specifications required to build repeatable test setups.

When performing a scan according to EN 50147-1, technicians do not just test solid walls. They focus heavily on structural discontinuities where RF leaks are most likely to occur:
