EN 50147-1 (titled "Anechoic Chambers — Part 1: Shield Attenuation Measurement") is a European standard specifying procedures for measuring the shielding effectiveness of electromagnetic enclosures across 9 kHz to 40 GHz
EN 50147-1 PDF: Understanding Shield Attenuation Measurement Standards
Accessing the official PDF document is crucial for laboratories aiming for ISO/IEC 17025 accreditation. The document contains explicit instructions regarding:
To ensure these chambers perform correctly, engineers rely on the European standard . This article provides a comprehensive overview of the standard, its testing methodologies, and how to interpret its requirements when working with compliance documentation. What is EN 50147-1? en 50147-1 pdf
The global standard for measuring the shielding effectiveness of electromagnetic shielding enclosures. Most of the mathematical and physical principles in EN 50147-1 align directly with IEEE 299.
The distance between the antennas must match the exact distance planned for the actual shield test. The received power level ( Prefcap P sub r e f end-sub ) or voltage ( Vrefcap V sub r e f end-sub ) is recorded across all target frequencies. 2. Enclosure Positioning (The "Shielded" Measurement)
It provides the authoritative, recognized methods needed to certify an EMC test facility for CE marking or other compliance needs. EN 50147-1 (titled "Anechoic Chambers — Part 1:
Personnel and equipment access doors (gaskets and fingerstrips) Ventilation honeycomb panels and HVAC ducts Power and signal line filter entries Coaxial RF penetration panels Structural panel joints and corners
To ensure comprehensive evaluation across different wave behaviors, EN 50147-1 requires testing across various frequency bands using specific magnetic, electric, and plane-wave fields:
Enclosures designed to prevent external RF signals from entering. What is EN 50147-1
Are you planning to or validate an existing setup ?
Utilizes biconical and log-periodic antennas to test the structural integrity of the shield.
