Shielding Effectiveness Testing
Laboratory testing and on-site testing capability
EMC Bayswater can perform NATA accredited Shielding Effectiveness Testing to MIL-STD 285 & IEE STD 299. Shielding Effectiveness Testing is carried out to assess the attenuation (suppression) performance of shielding installed in a building or that of shielded enclosures used for scientific, medical research and other purposes.
EMC Bayswater are NATA accredited for MIL-STD-285 & IEE 299 shielding effectiveness testing and have perform many shielding tests both in our fully equipped laboratory and on site at various private, commercial, and military work places.
We can measure magnetic fields, electric fields, plane waves, etc. The most widely accepted shielding effectiveness standards are MIL-STD-285 and IEEE std 299. Our shielding effectiveness frequency capability range is from 10kHz to 40GHz usually with a dynamic range over approximately 100dB.
We can test a range of materials individually such as Lycore magnetic panels, absorbing sheets, penetrations, patch panels, filters, windows and more.
What are electromagnetic shielding and shielding effectiveness?
Electromagnetic radiation consists of coupled magnetic fields (H field) and electric fields (E field) components. For many purposes, these magnetic and electric fields are required to be excluded or contained within an environment or area such as a shielded enclosure. Effective Uses of Electromagnetic Shielding would include telecommunication equipment racks, MRI, EMC testing chambers as found at EMC Bayswater.
How does electromagnetic shielding work and what affects the shielding effectiveness?
Shielded enclosures can fall under the banner of many naming conventions such as ‘Faraday cage’, ‘screened room’, ‘shielded enclosure’, ‘indoor open area test site (iOATS)’, ‘EMC chamber’. They are all essentially a means to eliminate or attenuate an electromagnetic source between the inner and the outer of the enclosure.
