MIL-G-83528B: General Specification for Gasketing Material, Conducting Shielding Gasket Electronic, Elastomer, EMI / RFI

This standard precedes the MIL-DTL-83528B standard.

The MIL-DTL-83528C standard involves the measurement of shielding effectiveness of gasketing material, specifically of elastomeric shielding gaskets. The following material of which these gaskets are made of type qualifies 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 will be determined by its ability to electrically bond a test cover panel to an enclosure flange so the radiated RF plane wave will attenuate through a 24-by-24-inch opening. The enclosure needs to be large enough so no part of the transmitting antenna is within one meter of any enclosure surface.
