En 50147-1 Pdf [360p 2026]

The European Standard EN 50147-1 provides the official methodology for measuring electromagnetic shielding effectiveness in high-performance enclosures. It is the primary reference for testing shielded rooms and anechoic chambers to ensure they prevent external interference or internal data leakage. Understanding the EN 50147-1 Standard

Q2: Can I use EN 50147-1 for a GTEM cell?

A: No. GTEM cells use a different principle. For GTEMs, refer to IEC 61000-4-20. EN 50147-1 is exclusively for metal enclosures with absorber lining. Method A (Absorber-lined chamber method): Uses absorbers to

• Method A (Absorber-lined chamber method): Uses absorbers to reduce reflections, suitable for most anechoic chambers.
• Method B (Reverse method/TEM waveguide): Used for smaller enclosures or specific frequency ranges.
