Summary of MIL-G 83528 Regulatory Compliance Testing

The MIL-DTL-83528C standard evaluates the shielding effectiveness of gasketing material, specifically of elastomeric shielding gaskets. A list of materials in which gaskets are made is specified below. These materials are qualified under this standard:

  1. Silver-plated copper-filled silicone
    • rated for shielding effectiveness of a 110-dB plane wave at 10 GHz
  2. Silver-plated aluminum-filled silicone
    • rated for shielding effectiveness of a 110-dB plane wave at 10 GHz
  3. Silver-plated copper-filled flurosilicone
    • rated for shielding effectiveness of a 110-dB plane wave at 10 GHz
  4. Silver-plated aluminum-filled silicone
    • rated for shielding effectiveness of a 90-dB plane wave at 10 GHz
  5. Medium pure silver-filled silicone durometer
    • rated for shielding effectiveness of a 110-dB plane wave at 10 GHz
  6. Pure silver-filled flurosilicone
    • rated for shielding effectiveness of a 110-dB plane wave at 10 GHz
  7. Silver-plated copper-filled silicone
    • rated for shielding effectiveness of a 110-dB plane wave at 10 GHz
  8. Pure silver-filled high durometer silicone
    • rated for shielding effectiveness of a 110-dB plane wave at 10 GHz
  9. Pure silver-filled low durometer silicone
    • rated for shielding effectiveness of an 80-dB plane wave at 10 GHz
  10. Copper-filled silver-plated high durometer
    • rated for shielding effectiveness of a 110-dB plane wave at 10 GHz
  11. Nickel-filled silver-plated silicone
    • rated for shielding effectiveness of a 100-dB plane wave at 10 GHz
  12. Glass-filled silver-plated silicone
    • rated for shielding effectiveness of a 100-dB plane wave at 10 GHz

Measurements are made using the plane wave shielding effectiveness method. The gasket is determined by its ability to electrically bond a test cover panel to an enclosure flange. The radiated RF plane wave will attenuate through a 24-by-24-inch opening. Furthermore, the enclosure needs to be large enough so no part of the transmitting antenna is within one meter of any enclosure surface.
