MIL-STD-1605 Procedures For Conducting A Shipboard Electromagnetic Interference Emi Survey Surface ShipThis standard provides the procedures for demonstrating compliance with the intra and inter-system electromagnetic compatibility EMC, hull-generated Intermodulation Interference IMI, and electrical bonding requirements of MIL-STD-464 for naval surface ships. In addition, an EMI survey is required for new construction ships and ships receiving overhauls or other major repair work that changes the ships electromagnetic configuration.

6.  NOTES

(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)

6.1  Intended use.  The requirements and test methods covered by this standard are intended to determine the EMC posture of the interface between shipboard equipments and the operational electromagnetic environment. Copies of the completed Data Item Descriptions (DIDs) should be forwarded to the contracting entity and cognizant program manager.

6.2  Acquisition requirements.  Acquisition documents should specify the following:

a.    Title, number, and date of this standard.

6.3  Associated Data Item Descriptions (DIDs).  This standard has been assigned an Acquisition Management Systems Control (AMSC) number authorizing it as the source document for the following DIDs.  When it is necessary to obtain the data, the applicable DIDs must be listed on the Contract Data Requirements List (DD Form

1423).

DID Number                                       DID Title

DI-EMCS-81782                                Electromagnetic Interference Survey Test Procedure (EMISTP) DI-EMCS-81777                                Electromagnetic Interference Survey Test Report (EMISTR)

The above DIDs were current as of the date of this standard.  The ASSIST database should be researched at https://assist.daps.dla.mil/quicksearch/ to ensure that only current and approved DIDs are cited on the DD Form

1423.

6.4  Test equipment.  All test equipment utilized should have valid calibration certificates/stickers.  Near field probes generally do not have certificates and, therefore, model numbers can be provided.  The scanning receiver, or spectrum analyzer, should be capable of a frequency range of 100 kHz to 6 GHz, with a combined input Noise Figure (NF) of 30 dB or less.

6.5  Subject term (key word) listing. E3
