Overview

ASTM F1068-90(2023) specifies the design, dimensions, and requirements for manufacturing double, individually dogged, gastight and airtight doors-fabricated from steel or aluminum-for personnel access through bulkheads in marine environments. These doors are engineered to maintain bulkhead integrity, ensuring air and gas tightness, which is essential for marine safety, compartmentalization, and operational reliability. This standard works in conjunction with ASTM F1073, which covers the essential door fittings used in marine applications.

Key Topics

• Material Requirements
  • Covers steel (ASTM A36/A131M) and aluminum (ASTM B209) panels, stiffeners, and frames.
  • Specifies use of neoprene or equivalent gaskets (MIL-R-900), and both steel and aluminum gaskets retainers and stiffeners.
• Design and Construction
  • Double-door design is individually dogged to ensure each panel achieves effective airtightness and gastightness.
  • Frames and panels must conform to specified principal dimensions and mechanical tolerances for fit and function.
  • All sharp edges are removed to provide safe handling and operation.
• Finishing and Corrosion Protection
  • Steel components require zinc-rich primer coatings.
  • Aluminum components undergo vinyl wash primer and anti-corrosion priming.
  • Supplementary treatments and specific primers are covered for high-demand environments.
• Testing and Certification
  • Each door must sustain a 5 psi (34 kPa) internal pressure and demonstrate no deformation; proof tested at 7.5 psi (50 kPa).
  • Airtight and gastight performance certification is required before delivery.
• Product Marking and Packaging
  • Clear labeling for identification, including purchase order number, ASTM designation, and nominal size.
  • Secure crating or palletizing of door sets for safe shipment, with protective measures for gaskets.

Applications

• Marine Vessel Construction
  Essential for ships, offshore structures, and naval vessels where maintaining air and gas-tight compartmentation is critical for crew safety and vessel integrity.
• Bulkheads and Compartmentalization
  Used in forming fire and smoke barriers, ensuring controlled atmosphere in select vessel compartments.
• Retrofitting and Vessel Repairs
  Provides guidance for consistent, safety-focused door replacement or upgrades on existing marine assets.
• Compliance with International Maritime Regulations
  Adoption of ASTM F1068-90(2023) supports compliance with shipping class rules and international safety standards.

Related Standards

• ASTM F1073 – Standard Specification for Door Fittings, for Watertight/Gastight/Airtight, Weathertight, and Non-Tight Doors for Marine Use.
• ABS Rules for Building and Classing Steel Vessels – Reference for construction, welding, and inspection of marine steel structures.
• MIL-R-900 – Rubber Gasket Material, 45 Durometer Hardness.
• MIL-C-81706 – Chemical Conversion Coating for Aluminum and Aluminum Alloys.
• MIL-P-24441 – Epoxy-Polyamide Paint.
• ZZ-R-765 – Rubber, Silicone for special gasket requirements.
• DoD-STD-2138 – Metal Sprayed Coating Systems for Corrosion Protection.

Practical Value

By adhering to ASTM F1068-90(2023), marine industry professionals ensure that double, individually dogged doors meet stringent safety and durability requirements for air and gas tightness. This not only improves vessel safety but also supports regulatory compliance and operational reliability in harsh marine environments. The specification’s clear guidance on material, construction, testing, and marking facilitates efficient procurement, manufacturing, and quality assurance for marine doors worldwide.
