17025 ACCREDITED TESTING/MEASUREMENT OF SHIELDING EFFECTIVENESS !!

Testing and Measurement of Shielding Effectiveness is a compulsory activity which needs to be performed for applications which use shielded rooms, enclosures, anechoic or semi-anechoic chambers for EMI/EMC testing, Magnetic Resonance Imaging (MRI) etc. This activity requires specialised equipment like antennae, signal generators, amplifiers, attenuators and more importantly qualified and trained persons to undertake it

BNNEMR provides accredited Shielding Effectiveness testing for the following:-

  • Anechoic and Semi anechoic chambers, rooms and enclosures
  • Defence installations where high levels of shielding are required
  • Secure buildings and facilities such as defence, Tempest, government and financial institutions where electronic security is required
  • Radio communications transceiver test rooms
  • Equipment enclosures, racks and smaller cabinets
  • Hospital medical theatres and medical suites housing medical and diagnostic equipment such as MRI, X-ray imaging and other EMI/RFI susceptible equipment
  • Shielded enclosures and buildings where the existing RF ambient signals from nearby high power commercial transmitters, portable and mobile transmitters pose an interference threat to computer installations
  • Audio/TV studios and message centres

BNNEMR Technologies can perform the RF attenuation testing in the laboratory or on site in urban or remote locations. 17025 accredited procedures ensure accurate and repeatable tests with the highest possible confidence in the results. If an enclosure fails to meet the required performance, EMC Technologies can isolate the problem and provide recommendations for appropriate and cost effective solutions.

For the highest level of confidence, always independent accredited test is strongly recommended for obvious reasons

BNNEMR has acquired all necessary test equipment required to undertake this activity and offers measurement/testing of Shielding Effectiveness of shielded enclosures, rooms between 9 KHz to 40 GHz. The onsite testing and measurement of Shielding Enclosures is carried out as per following scope:-

  • IEEE 299: 2006.
  • Enclosures and boxes having all dimensions between 0.75m to 2m as per IEEE 299.1: 2013.
  • Appendix A of MIL Std. 188-125.2: 3 Mar 1999.
