DDS-078-1

• DDG 1000 has a deckhouse which will be
  constructed from fiber reinforced plastic
  (Composite) materials.
• Fire performance of composite materials is
  covered under DDS-078-1, Composite materials,
  Surface ships, Topside structural and other
  topside applications Fire performance
  requirements
• Contains fire performance requirements for
  Structural composites such as flame spread, smoke
  generation, fire growth, fire resistance, and
  structural integrity.
• Contains fire performance requirements for non
  structural composite items such as weather deck
  gratings, louvers, ducting, valves, etc.
• Rev 1 is under review, and includes
• GRP piping requirements
• Revision of structural integrity section for
  composite structures.
• Revision of smoke index and carbon monoxide
  limits.
• Addition of the Table which lists Navy approved
  Composite N-Class divisions.

MIL-STD-X129

• Draft MIL-STD-X129, Fire Resistance of U.S.
  Naval Ships
• Draft MIL-STD-X129 provides the detailed test
  procedure and acceptance criteria for the fire
  resistance (i.e., prevention of fire spread
  through a boundary) for divisions (e.g.,
  bulkheads and overheads/decks) and their
  penetrations on U.S. Navy ships.
• Institutes two Classes of Fire Resistant
  Divisions
• N-Class N-Class Divisions are those divisions
  (bulkheads and decks) that are designed to
  protect against structural failure and prevent
  the passage of fire and smoke when exposed to a
  rapid rise hydrocarbon fire exposure (Class B).
  The minimum fire test duration is 30 minutes. In
  addition, N-Class divisions are designed to
  prevent excessive temperature rise for a
  designated test period such as 30 minutes (N-30).
  
• AN-Class AN-Class Divisions are those divisions
  (bulkheads and decks) that are designed to
  protect against structural failure and prevent
  the passage of fire and smoke when exposed to an
  IMO A. 754(18) fire exposure (Class A). For all
  AN-Class divisions, including those with
  penetrations, the test duration is a minimum of
  60 minutes. In addition, AN-Class divisions are
  designed to prevent excessive temperature rise
  for a designated test period such as 60 minutes
  (AN-60).

15
MIL-STD-X129

• Fire Resistant Divisions
• N-30 Unrestricted Application means that
  insulation is installed either on both sides or
  on the non fire side to meet the requirements for
  temperature rise during the fire test.
• N-30 Restricted Application means that
  insulation is installed on the side from where
  fire threat is anticipated. The division is
  classified as Fire Resistant only in one
  direction, from the fire side where the
  insulation is placed.
• N-0 Steel is inherently (without insulation) N-0
  when used in thickness greater than 4.5 mm with
  suitable scantlings. N-0 means it prevents
  structural collapse and passage of flame and
  smoke.
• Aluminum melts when exposed to Class A or B fire,
  and hence requires insulation for any kind of
  fire resistance rating.

MIL-STD-1623E

• MIL-STD-1623 E, Fire Performance Requirements and
  Approved Specifications for Interior Finish
  Materials and Furnishings
• MIL-STD-1623E is a revision of MIL-STD-1623D and
  updates fire performance criteria for materials
  in
• bulkhead sheathing
• overhead sheathing
• Furniture
• draperies and curtains
• deck coverings
• Insulation and
• bedding applications.

Composite BerthInterim Fire Test Procedure

• INTERIM FULL SCALE FIRE TEST METHOD FOR COMPOSITE
  SHIPBOARD BUNKS
• Ser 05P4/110 October 2006
• Fire Source 50 kW for 5 minutes followed by 100
  kW for 10 minutes
• Similar to NAVSEA 05Z6 PD 5-04A

19
Bonded Fasteners

• The U.S. Navy is considering attaching furniture
  items to studs that are adhesively bonded to the
  ship boundaries as an alternative to welded
  studs for installing specific USS WASP and LPD-19
  berths and lockers.
• It is believed that this technology could
  provide significant cost/time savings benefits
  for ship overhauls and repairs.
• This technology could also provide deployed ships
  with the capability to perform repairs or
  installations that are currently difficult or
  impossible to perform with the current welded
  studs which require fire watch for hot works.
• Ser 05P4/xxx (Under review) provides the fire
  performance requirements of adhesively bonded
  studs used to mount furniture items to ship
  boundaries. Ship boundaries may consist of steel,
  aluminum, or composites.
• Adhesively bonded studs may be permitted in
  compartments outfitted with sprinklers. In
  addition, the boundary containing the bonded
  studs must have at least an N-30 fire resistance
  rating or the adjacent compartments must be
  outfitted with sprinklers.
