Sliding watertight doors consist of four types: type IA - horizontal doors, type IB - vertical doors, type IIA - horizontal doors, and type IIB - vertical doors. Watertight doors consist of three classes: class 1 - doors that are hinged and dogged, class 2 - sliding doors that are operable both locally and remotely by hand gear, and class 3 - sliding doors that are operable both locally and remotely by hand and by power. Hydrostatic test and visual examination shall be performed to meet the requirements prescribed.
SCOPE
1.1 This specification covers the design, manufacture, and testing of sliding watertight door assemblies intended to ensure the watertight integrity of personnel access openings in watertight bulkheads.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM F1196-19 is the internationally recognized standard specification for sliding watertight door assemblies, published by ASTM International. This specification outlines the essential requirements for the design, manufacture, and testing of sliding watertight doors intended for use in personnel access openings within watertight bulkheads, particularly in marine environments. By adhering to the provisions in ASTM F1196-19, manufacturers, shipbuilders, and regulatory agencies ensure the watertight integrity and operational reliability of these critical safety components in vessels.

The standard encompasses multiple door types and classes, provides guidelines for material selection, manufacturing processes, and delineates test procedures to ensure compliance. It is developed in accordance with established principles for international standards and aligns with applicable maritime regulatory frameworks, such as those set forth by the International Maritime Organization (IMO) and the U.S. Coast Guard.

Key Topics

• Scope and Purpose: Covers the requirements for sliding watertight doors installed in bulkheads to maintain watertight integrity in vessels, ensuring marine safety.
• Door Types & Classes:
  • Types: Horizontal (Type IA, Type IIA) and vertical (Type IB, Type IIB) doors, with both standard and special requirements doors.
  • Classes: Class 2 (sliding, hand gear operation) and Class 3 (sliding, hand and power operation). Hinged doors (Class 1) are excluded.
• Design Requirements:
  • Substantial and rigid construction to withstand prescribed water pressure heads.
  • Replaceable watertight interface (e.g., gasket or brass strip) between door and frame.
  • Features to maintain watertightness as components wear during normal use.
• Material & Manufacturing:
  • Corrosion-resistant and ABS-accepted materials for all watertight components.
  • Stainless steel or brass fasteners.
  • Specified minimum thickness for structural elements and finishing procedures for longevity.
• Testing & Certification:
  • Hydrostatic pressure tests and visual inspections for each assembly.
  • Certification documenting compliance with ASTM F1196-19.
  • Additional shock and fire-resistance testing where specified.
• Marking and Packaging:
  • Permanent, corrosion-resistant nameplates identifying manufacturer, performance ratings, and compliance information.
  • Requirements for shipment, marking, and preservation for delivery integrity.

Applications

• Marine Vessels: Primarily designed for use in ships, commercial vessels, and maritime installations where maintaining watertight compartmentalization is essential for crew safety and vessel integrity.
• Bulkhead Access: Installation in watertight bulkheads, ensuring personnel access zones retain water resistance in the event of flooding.
• Regulatory Compliance: Ensures conformity to IMO rules, ABS regulations, U.S. Coast Guard requirements, and other maritime authority standards.
• Safety Equipment: Utilized as essential shipboard equipment in the outfitting and construction phases as well as in maintenance and upgrade projects.
• Fire and Shock Resistance: Designs may include insulation and structural features to enhance resistance to fire spread and shock impacts per military and IMO standards.

Related Standards

• ASTM F1197 - Specification for Sliding Watertight Door Control Systems.
• ASTM A36/A36M - Specification for Carbon Structural Steel.
• MIL-DTL-901 - Shock testing requirements for shipboard machinery and equipment.
• ABS Rules - American Bureau of Shipping Rules for Building and Classing Steel Vessels.
• CFR Title 46, Parts 159.010 and 163.001 - U.S. Coast Guard regulations for door and control system acceptance.
• IMO FTP Code - International Maritime Organization Fire Test Procedures Code.

ASTM F1196-19 is a critical standard for stakeholders in the maritime industry, supporting the design and implementation of robust, compliant sliding watertight door assemblies for enhanced marine safety and vessel performance.

to a water height of at least 1 m above the sill on the centerline of the door.
6.3 There shall be a replaceable interface between the door and frame assemblies, such as a brass rubbing strip or resilient
gasket, to ensure watertightness between door and frame at the design pressure head.
6.3.1 The replaceable interface may be incorporated into the door assembly, the frame assembly, or both.
6.3.2 Assemblies shall be designed and constructed so as to be capable of preventing the passage of smoke and flame to the
end of the 1-h standard fire test described by IMO FTP. When specified by the purchaser, assemblies shall also be insulated to
prevent the transfer of heat to at least the same degree as the adjacent bulkhead. A fire test is not required if the assembly design
F1196 − 19
FIG. 2 Type IB Door and Frame
incorporates details that have been demonstrated such as by a fire test on a similar door with smaller dimensions, to prevent the
passage of smoke and flame. Also, a separate pressure test to determine continued watertightness after the standard fire test is not
required.
6.3.3 Assembles shall be designed in such a manner that the replaceable interface will be protected from damage when the door
is in the open position.
6.4 Sliding watertight door assemblies shall be designed to provide sufficient allowance or means of adjustment to maintain the
original watertight integrity as the watertight joint wears through normal usage.
6.5 Means shall be provided for lubrication of all parts necessary for satisfactory operation.
6.6 Sliding watertight door assemblies shall have a maximum horizontal opening of 48 in. (122 cm).
6.7 Door Assemblies—Type I (standard) doors are designed for a pressure head of 20 ft (6 m) of water. Type II (nonstandard)
doors shall be designed for the pressure head as specified in 3.1.5 and 5.1.7, but not less than 20 ft (6 m) for doors installed below
the bulkhead deck.
6.7.1 The door panel and panel stiffener assembly shall be designed based on 40 % of the yield strength of the material used
to construct the panel and its stiffeners (see 7.1).
6.7.2 The door panel and stiffener assembly shall have a maximum deflection of span/240.
6.7.3 Retaining grooves or aligning strips shall be provided at the tops and bottoms of horizontal assemblies and at the sides
of vertical assemblies to maintain doors in proper alignment when they are not in the closed position.
6.8 Frame Assemblies—The door frame shall be continuous on all four sides. The door frame shall be of sufficient rigidity to
maintain a watertight seal under the applicable operating conditions and the design head as specified in 6.7.
6.8.1 If the door frame is to be welded to the bulkhead on a reinforcing member, which acts as a secondary frame and which
is continuous around the door opening, the I of that member may be included to obtain the required frame I value. (See also the
Appendix X1.)
6.8.2 The frame extension for sliding watertight doors shall be made in one continuous piece, or suitable construction shall be
used to ensure proper alignment.
6.8.3 Horizontal doors shall be supported by lubricated rollers to maintain alignment and minimize friction.
6.8.4 The bottom of the frame assembly shall be designed so the door will not be prevented from closing properly by
lodgements of dirt or debris.
6.8.5 A sill plate of ⁄16-in. (5-mm) minimum thickness may be used to cover the bottom trackway provided it is design
