1.0 PURPOSE This specification defines
the Electromagnetic Environmental Effects (E3) requirements for DDG-1000
Class General Material purchased by BIW. E3 requirements for General material
are identified by a T016, T017, T018,
T019, T020 or T021 SDRL Code on the P.O. The objective of these
requirements is to provide equipment for a ship to allow it to complete all
assigned missions while operating in a shipboard electromagnetic environment. 2.0 ELECTROMAGNETIC INTERFERENCE (EMI) Electronic,
electrical, and electromechanical equipment, subsystems, and systems shall
meet the requirements for Surface Ship applications as defined in
MIL-STD-461E dated 20 August 1999,Table V titled Requirement Matrix, as
tailored below. Portable equipment and equipment installed in multiple
locations shall meet the EMI requirements for the most stringent location of
use. 2.1 COTS Equipment COTS/NDI (Commercial Off-The-Shelf /
Non-Developmental Items) electronic, electrical, and electromechanical
equipment and subsystems shall not suffer interference from nor degrade the
shipboard electromagnetic environment.
Therefore the COTS equipment, in its shipboard installation, shall meet
the EMI requirements of MIL-STD-461. The shipboard installation may include
shielded enclosures or cabinets, filtering, or other suitable techniques, as
required, to enable compliance of the COTS equipment to MIL-STD-461
requirements. The use of non-modified COTS is permissible only with written
permission from the Navy's Technical Authority for Shipboard Electromagnetic
Compatibility. To assist in meeting this requirement, the basic COTS
equipment, without its installation isolation, should meet the minimum E3
requirements from the NVR Part 4, Chapter 2, Section 7, Table 9 which
includes IEC 61000-4-2, IEC 61000-4-3, IEC 61000-4-4, IEC 61000-4-5, IEC
61000-4-6, IEC 60533, and CISPR 16-1,16-2. The CISPR emission test
requirements may be replaced with those of FCC CFR 47, Part 15. Navigation
equipment shall also meet the EMI requirements of the environmental tests
specified in IEC Publication 60945, Maritime Navigation and Radio
Communication Equipment and Systems - General Requirements - Methods of Testing
and Required Test Results. The EM performance of COTS/NDI equipment, without
its installation isolation, shall be documented, preferably with a copy of
the EMI/EMC test report using SDRL T017 as a guide. For COTS/NDI equipment,
which is electromagnetically isolated (shielded enclosures or cabinets,
filtering, or other suitable techniques) in its installation such as
equipment installed in an EME (Electronics Modular Enclosure), the subsystem
of the equipment in its enclosure shall be demonstrated to meet MIL-STD-461.
When two or more COTS equipments are installed within the same enclosure,
electromagnetic compatibility shall be demonstrated between and among the
equipments within the enclosure. Test laboratories accredited by NIST NVLAP
or A2LA or an equivalent accrediting body shall be used to accomplish all
electromagnetic testing. 2.2 Equipment Connected
