The standard defines the required instrumentation and the setup of transmitting and receiving antennas within and outside the enclosure. Proper calibration practices are outlined, as noted on ShieldingTests.com . 4. Shielding Attenuation Calculation
To obtain a legitimate, fully compliant copy of the EN 50147-1 PDF, you should purchase it through recognized national standards organizations and authorized distributors, such as:
Following the PDF ensures that tests can be repeated and validated, which is important for quality control in chamber manufacturing.
Invest in the standard, and it will pay dividends in regulatory compliance and measurement confidence. en 50147-1 pdf
If you need a PDF copy of the standard, you can search for it on various websites, such as:
The receiving antenna is placed inside the chamber directly opposite the transmitter, maintaining the identical calibration distance. The attenuated signal strength ( Vchambercap V sub c h a m b e r end-sub ) is recorded. Step 3: Calculating Shielding Effectiveness (SE)

This standard is a critical quality control tool for ensuring confidence in sensitive EMC test results. The primary users include:
Using this European standard ensures that a shielded enclosure meets its intended performance characteristics. Benefits include:
Shielding effectiveness is expressed in decibels (dB). It is calculated using the ratio of the received signal strength without the shield ( E1cap E sub 1 H1cap H sub 1 The attenuated signal strength ( Vchambercap V sub
Often available through reputable industry standards aggregators. Conclusion
The standard is crucial for validating that an enclosure provides the necessary environment for EMI (Electromagnetic Interference) testing, radiated immunity tests, or for preventing eavesdropping in sensitive information facilities. Key Details of the Standard
