Shielding effectiveness test following the Standard ASTM D4935-18:
ASTM D4935-18 - MEASURING THE ELECTROMAGNETIC SHIELDING EFFECTIVENESS OF PLANAR MATERIALS
The Standard ASTM D4935-18
describes how measuring the electromagnetic (EM) shielding effectiveness (SE) of a planar material for a plane, far-field EM wave.
The measurement method is valid over a frequency range of 30 MHz to 1.5 GHz
. These limits are not exact, but are based on decreasing displacement current as a result of decreased capacitive coupling at lower frequencies and on overmoding (excitation of modes other than the transverse electromagnetic mode (TEM)) at higher frequencies for the size of specimen holder described in this test method.
This test method is not applicable to cables or connectors.Emctest Technologies is a laboratory that performs shielding effectiveness tests on site
, directly to the customer, in Italy and in Europe
, or at its headquarters in Rimini - Italy.
