14、1. SCOPE 1.1 Scope. This standard covers standard methods for swage tubes, stuffing tubes, and kickpipes on surface ships and submarines. 1.1.1 Application. These installation methods are to be used by all installing activities. These methods do not identify ship or type, but do establish minimum st
15、andards of acceptance for Naval ships. It is the responsibility of the user activity to determine which method satisfies their requirements. It does not authorize relaxation of any requirement specifically invoked by new construction, conversion, overhaul, or refurbishment contracts. In instances wh
16、ere deviated design requirements (for example, ship type, ship class, and so forth) conflict with the requirements of this standard, the requirements of this standard govern. Any deviation for electric plant installation identified in this standard is to be submitted to NAVSEA 05Z3 for resolution. 2

Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 3. DEFINITIONS 3.1 Co
30、llective protective system (CPS). CPS is a system designed to inhibit the entry of chemical, biological, and radiological contaminants into collective protection zones on board ships. A collective protection zone is a section of the ship, which is defined by a physical boundary that inhibits the ent
31、ry of CBR contaminants into the zone. A total protection zone is pressurized to 2 inches WG and its supply ventilation air is continuously filtered to remove chemical vapors and CBR particulate and aerosols. 3.2 Community stuffing tube for bulkheads. Community stuffing tube for bulkheads is a system
32、 of passing multiple cables through ballast tank bulkheads on submarines. 3.3 Kickpipe. Kickpipe is a pipe welded into the deck with a stuffing tube attached. Kickpipes provide protection of electrical cable at deck penetrations and are used to clear an obstruction or preserve alignment. Kickpipes m
33、ay be aluminum, steel, stainless steel, or brass to suit the installation or standard pipe sizes to suit the required stuffing tube. 3.4 Metal stuffing tube. Metal stuffing tube is a system of passing single electrical cable through decks and bulkheads and entering enclosed equipment on Naval ships.
34、 Metal stuffing tubes are manufactured in accordance with MIL-S-24235. Stainless steel is an alternative material which should be considered for use in applications highly susceptible to corrosion.

35、STD-2003-3A(SH) 3 3.4.1 Nylon stuffing tube. Nylon stuffing tube is a system of passing single electrical cable through electrical equipment on Naval ships. Nylon stuffing tubes are manufactured in accordance with ASTM F1836M. 3.5 Multiple cable penetrator (MCP). MCP is a system of passing multiple
36、cables through watertight and non-watertight bulkheads and decks in order to provide watertight, airtight, and firetight penetration of electrical cable. 3.6 Swage tube. Swage tube is a system of passing single cables through decks on Naval ships that combines the features of the stuffing tube and k
37、ickpipe. 4. GENERAL REQUIREMENTS 4.1 Cable penetrations.
