Organization:
AIR FORCE - 82 - San Antonio Air Logistics Center
Year: 1954
Abstract: This specification covers shielding enclosures, (screen rooms) which are provide specified degrees of attenuation of electromagnetic fields within specified frequency ranges for the purpose of test and alinement of electronics equipment and other related purposes.
- Shielding enclosures shall be of the following type, as specified:
Intended Use: The shielding enclosure covered by this specification is intended to provide an interference-free enclosure for the operation, testing, and alinement of electronic equipments. The completely assembled enclosure is intended to attenuate electromagnetic fields from internal or external sources that cause undesirable interference with the test and alinement or operation of all types of electronic receivers. It is intended that the enclosure will be used in the continental United States and at outlying maintenance bases.
- Shielding enclosures shall be of the following type, as specified:
Type I - Double shielding, wire mesh, cell-type construction, demountable, providing a minimum of 100 db attenua- tion to electromagnetic fields within the frequency range of 100 kc to 10,000 m.
