This specification covers the principal shapes and dimensions, and mechanical requirements for the manufacture of two types of individually dogged watertight, gastight/airtight, and weathertight doors of steel, aluminum, and glass-reinforced plastic construction. These doors, which shall be complete with frames, are built for access through bulkheads by marine personnel, and are intended to maintain the structural and tightness integrity of the bulkheads. The doors shall be classified into groups according to their area of application, as follow: Group A—watertight doors in the bridge front bulkhead and the unprotected bulkhead of deckhouses/superstructures, and deckhouses that enclose machinery openings; Group B—watertight doors in the deckhouse bulkheads partially protected or in the bulkhead of deckhouses/superstructures, and not around machinery openings, watertight and airtight doors below weather deck; Group C—airtight /gastight doors in the aft end bulkhead of the bridge, forecastle, and deckhouses at the weather deck level; and Group D—weathertight doors in the deckhouse above the weather deck level. All doors shall be certified for applicable tightness integrity prior to delivery.

1.1 This specification, to be used in conjunction with Specification F1073, covers the principal dimensions and the mechanical requirements for manufacturing steel, aluminum, and glass-reinforced plastic, individually dogged, watertight, gastight/airtight and weathertight doors, for personnel access through bulkheads, complete with frames, for marine use intended to maintain the structural and tightness integrity of bulkheads.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 The following safety hazards caveat pertains to the test method portion, Section 8, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
