MET Labs is one of just a few labs that employs an advanced in-house reverberation (mode-stirred) chamber for testing shielding effectiveness (SE).
We can efficiently and accurately test cables, materials, and absorbers to IEC 61000-4-21 and other SE standards.
MET can easily develop sound engineering measurement techniques to quantify the SE of your product. Our process involves creating detailed SE Test Plans used to insure accurate and repeatable test results.
MET Laboratories has years of experience to assure our customers that the evaluation reflects the electrical attenuation performance of the material. Often times, our test report becomes supporting documentation for our customer’s end-user contractual requirement, where Independent Test Laboratory results verify the electrical performance of the material being tested.
MET Laboratories can use standardized SE test methods, or use standards such as IEEE-299 or ASTM E 1851 or MIL-STD-285 as procedural guides to the evaluation.
MET also tests shielding effectiveness to these military standards:
MET's testing of the electromagnetic shielding effectiveness of planar material to ASTM test method D4935-1 has benefitted from the pictured test fixture. Dynamic range of greater than 80dB is achievable.
