ASTM D4935: Standard Test Method for Measuring the Electromagnetic Shielding Effectiveness of Planar Materials
This test method provides a procedure for measuring the electromagnetic (EM) shielding effectiveness (SE) of a material due to a plane-wave, far-field EM wave. The test utilizes a coaxial transmission line to determine the shielding effectiveness of a given material. The test method is valid for a frequency range of 30 MHz to 1.5 GHz. Various thicknesses and types of materials can be tested to acquire a relative ranking of shielding effectiveness.
