Accredited Shielding Effectiveness Testing for Enclosures and Facilities
At EMC Technologies, we provide independent and accredited shielding effectiveness test services to help verify how well enclosures, rooms, buildings and materials attenuate unwanted electromagnetic energy.
Our testing services help organisations confirm that their EMI shielding solutions perform as specified, protecting sensitive equipment, communications systems and people from interference and signal leakage.
Why Test Your Shielding Performance?
Shielding environments are used to control electromagnetic emissions and susceptibility. However, performance can’t be assumed without measurement. A formal shielding effectiveness test confirms that installed shielding delivers the required attenuation across relevant frequency ranges.
Independent verification is critical where EMI / EMC shielding is used to:
- Protect mission critical systems from interference
- Prevent emissions from escaping from secure environments
- Demonstrate compliance for defence, medical, broadcast and industrial installations
- Validate supplier claims for shielded rooms, cabinets and materials
Without testing, even minor installation defects can significantly reduce RF shielding effectiveness.
Standards and Regulatory Compliance
At EMC Technologies, we perform shielding effectiveness test programs in accordance with recognised international standards, including:
- MIL-STD-285
- IEEE-STD-299
These standards are widely used across EMI shielding performance for defence, government, healthcare, telecommunications and secure commercial facilities.
All testing conducted by EMC Technologies is carried out using assessed procedures to ensure accurate, repeatable and defensible results
Our Shielding Testing Capabilities
We offer comprehensive shielding effectiveness test services for a wide range of applications, including:
- Shielded rooms, buildings and secure facilities
- Equipment enclosures such as racks, cabinets and housings
- Medical suites including MRI and diagnostic environments
- Broadcast studios, control rooms and RF test spaces
- Materials testing including panels, windows, coatings and conductive paints
At EMC Technologies, our capabilities cover both laboratory and on-site testing which allows us to assess EMI shield performance in urban, industrial and remote environments.
Shielding Effectiveness Testing Process
All shielding effectiveness test applications are planned to suit the enclosure type, frequency range and performance requirements.
Our process typically includes:
-
Review of shielding design, construction and intended use
-
Selection of an appropriate test standard and measurement method
-
Measurement of RF shielding effectiveness across relevant frequencies
-
Identification of leakage points, joints or penetrations
-
Clear reporting with quantified results and recommendations
Where shielding does not meet specification, our experienced team of engineers can isolate faults and advise on practical corrective actions.

Validate Your Shielding Performance with Accredited Testing
Independent testing is the most reliable way to confirm RF shielding effectiveness and to ensure long-term protection against interference and emissions leakage.
FAQs about Shielding Effectiveness Testing
What is a good shielding effectiveness rating?
Good shielding effectiveness levels depend on application and standard. However, many installations require attenuation ranging from 60dB to over 100dB across defined frequency levels.
How often should a shielded room be retested?
Retesting is recommended for a shielded room after installation, modification, relocation or if interference issues arise. Periodic testing is also common in regulated environments.
How do you measure shielding effectiveness?
A shielding effectiveness test measures signal attenuation between a transmitter and receiver positioned inside and outside the enclosure under controlled conditions.
Can you test the shielding of small components like gaskets?
Yes. At EMC Technologies, we can assess materials and components used for EMI / EMC shielding, including gaskets, panels and conducive elements.
