This standard is approved for use by the Department of the Navy and is available for use by all Departments and Agencies of the Department of Defense. 2. The increased use of elec
3、trical and electronic equipment aboard Naval ships introduces risk of electromagnetic interference (EMI) problems to ship operation and performance. As systems are added, they all contribute and could become susceptible to an intense electromagnetic environment (EME). Considering the corrosive salt
4、water environment in which ships must operate and the interaction of a ships electrically conductive metallic superstructure, topside hardware, antenna systems, etc., the potential for interoperability problems is significantly increased. Potential EMI and personnel safety problems related to electr
5、onic equipment operating in these environments are magnified because of: a. The need to establish and maintain a low impedance (Z), common reference ground for all electrical/electronic equipment b. The detrimental effects of: (1) Natural and manmade electromagnetic (EM) energy (2) Spurious and inte
6、ntional EM energy (3) Off-ship and own-ship, EM energy 3. MIL-STD-464 establishes electromagnetic environmental effects (E3) interface requirements and verification criteria for airborne, sea, space, and ground systems, including associated ordnance. This includes intra-ship and inter-ship electroma
7、gnetic compatibility (EMC), electromagnetic pulse (EMP), intermodulation interference (IMI), and electromagnetic radiation hazards to personnel, fuels, and ordnance. 4. This revision of MIL-STD-1310 has been expanded to include procedures for Electromagnetic Pulse (EMP) hardening. It also provides p
8、rocedures and guidance to more easily address MIL-STD-464 requirements in relationship to intra- and inter-ship EMC, hull-generated IMI, lifecycle E3 hardness, EMP, and electrical bonding. However, adherence to the procedures contained herein does not relieve the contractor from meeting the applicab
9、le ships operational performance requirements specified in the contract. 5. This document does not specify EMI reduction through frequency management, limits on operating power, or use of blankers. Grounding for personnel safety continues to be a major part of this standard, particularly in regard t
10、o commercial-off-the-shelf (COTS) equipment and non-developmental items (NDI). A separate appendix is included herein with procedures to identify whether COTS/NDI equipment meets appropriate safety requirements herein before use, and to provide direction to bring them into conformance when necessary
11、. This document does identify the E3 inspection and test procedures that can be used as measures of effectiveness of the EM control and personnel safety measures when installed/implemented. 6. Department of Defense (DoD) acquisition policy encourages contractor innovation, introduction of advancing
12、technology, and determination of the appropriate methods and materials to be used for all DoD acquisitions. Many effective shipboard EMI control measures and materials have been identified by the government and subsequently specified as requirements for ship construction and availabilities. Mandatin
13、g compliance works to the possible exclusion of equally effective industry-developed solutions. To avoid that possibility, this document defines EMC and safety requirements, and presents known effective solutions yet, when appropriate, allows the contractor an option to innovate a new solution with
14、cognizant technical authority approval. Because the appropriate performance demonstration inspections and tests have been identified herein, whichever method/material is used, its effectiveness in meeting the requirement can be determined. 7. Comments, suggestions, or questions on this document shou

This document specifies standard practices to facilitate achievement of the intra-ship and inter-ship electromagnetic compatibility (EMC), electromagnetic pulse (EMP), bond
46、ing, and intermodulation interference (IMI) requirements of MIL-STD-464. 1.2 Application. The requirements specified herein apply to metal and nonmetallic hull ships and are applicable during ship construction, overhaul, alteration, and repair. Requirements herein may be invoked upon contractor and
47、government (military and civilian) personnel. 1.3 Tailoring. The requirements herein may be tailored with NAVSEA 05H3, Navy technical warrant authority, approval. 1.4 New materials and technology. To achieve requirements of this standard while reducing lifecycle maintenance costs, implementation of
48、new materials and technology is encouraged. The new materials and technology should not prevent the ship from meeting all applicable MIL-STD-464 E3 performance requirements, and must not introduce EMI or safety problems. An example of new shipboard bonding and grounding technology is a flexible infr
49、astructure deck track system designed to provide equipment reconfigurability. 2. APPLICABLE DOCUMENTS 2.1 General.
