Warning: Be careful of "free PDF" sites. Many offer outdated drafts, corrupted files, or malware. The standard is copyright-protected; distributing it without permission is illegal in all EU member states.

Do not confuse EN 50147-1 with EN 50147-2, which deals with "Anechoic chambers – Part 2: Alternative test site suitability with respect to site attenuation." Part 1 focuses on the metal shield’s integrity, while Part 2 focuses on the internal absorber performance.

Once you have the legitimate PDF, it becomes the procedural backbone of your chamber validation report. Here is what a compliant test report must include (as per Section 8 of the standard):

Without referencing EN 50147-1 PDF’s procedures, your chamber validation will not be accepted by notified bodies for CE marking, FCC, or ISED certification.

Why is this document still so heavily searched? Because it underpins critical industries:

The shielding attenuation measurement setup diagrams are detailed. Low-quality scans often make these unreadable, leading to incorrect test setups.

Search your institution or company’s standards portal for BS EN 50147-1:1995. If you only need the method (not the official text), many EMC test labs publish summaries in their work instructions — search "shielding attenuation measurement EN 50147-1" to find publicly available extracts.

Overview

EN 50147-1 is part of a series of standards that focus on EMC, which is the ability of electrical and electronic equipment to operate as intended in its environment without being affected by or generating electromagnetic disturbances. The standard provides the necessary requirements and tests to ensure that equipment complies with the essential requirements of the EU's EMC Directive.

Scope

The scope of EN 50147-1 includes:

Normative References

The standard references several other European Norms, including:

Requirements

The standard outlines several requirements for equipment to comply with EMC:

Test Methods

The standard outlines several test methods to verify compliance with the requirements:

Conclusion

EN 50147-1 is an essential standard for ensuring the electromagnetic compatibility of electrical and electronic equipment in various environments. By complying with this standard, manufacturers can ensure that their equipment operates as intended and does not generate or suffer from electromagnetic disturbances. The standard provides a framework for testing and verifying compliance, which helps to ensure the safe and reliable operation of equipment.

The EN 50147-1 standard is a European technical specification focused on Anechoic Chambers, specifically regarding the measurement of shielding effectiveness.

This standard provides the methodology for testing how well an electromagnetic shield (like those used in anechoic chambers) performs. It is part of a three-part series: Part 1 (EN 50147-1): Shielding effectiveness measurement.

Part 2 (EN 50147-2): Site attenuation measurement (used for qualifying chambers for emissions testing).

Part 3 (EN 50147-3): Emission measurements in fully anechoic chambers. Key Content of the Standard en 50147-1 pdf

The document outlines the technical requirements for validating that an enclosure is properly "sealed" against electromagnetic interference (EMI).

Frequency Range: It typically covers measurements in the range of 9 kHz to 40 GHz.

Measurement Methods: It details the placement of transmitting and receiving antennas to ensure the enclosure meets specific decibel (dB) attenuation requirements.

Testing Procedures: It defines how to test critical points like doors, vents, and cable penetrations, which are the most common spots for leaks. Where to Access the PDF

For engineers and labs, compliance with EN 50147-1 is essential for EMC (Electromagnetic Compatibility) testing. Without a certified shield, external radio signals (like cell towers or Wi-Fi) can interfere with delicate measurements, leading to inaccurate product testing results.

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.
