TESTING SERVICES - Shielding Effectiveness

One of the more difficult tests to understand is shielding effectiveness or transfer impedance. The data from these tests may vary dramatically based on the test method selected, test fixture, test setup, measurement sensitivity, test personnel, etc. At Radiometrics all shielding effectiveness test are performed or supervised by NARTE Certified engineers. We will assist our clients to ensure that their tests are performed in a manner that yields valid, supportable, reproducible data consistent with the final application of their product.

a.		ASTM D4930		Measuring the Shielding Effectiveness of Planar Materials
b.		MIL T 81490		Transmissions Lines, Transverse Electromagnetic Mode
c.		Mil-Std 285		Attenuation Measurements for Enclosures
d.		MIL-STD 188-125-1		High-Altitude Electromagnetic Pulse (HEMP) Protection
e.		MIL-STD 1344A		Shielding Effectiveness of Multicontact Connectors
f.		IEC 61726:2001		Attenuation Measurements by Reverberation Chamber Method

We understand that many development projects are unique and the above set of standards may not always directly apply. Alternate tests are available. Our staff is on call to assist you in selecting, developing and executing any special needs.
