Ships and marine technology — Weathertight single-leaf steel doors
ISO 6042:2015 specifies the main dimensions, materials, quality and conditions of manufacture for weathertight single-leaf steel doors for application on board ships, in order to ensure interchangeability of the steel doors. The remaining dimensions, welding, and other details are left to the manufacturer. These doors generally conform to the requirements of the International Convention on Load Lines 1966 (ICLL66). The possibility for application of the doors to position 1 and position 2 has to be considered for each situation and, where necessary, the doors shall be provided with additional stiffening (see also Table 1). Users of this ISO 6042:2015 should note that while observing the requirements of this International Standard they should, at the same time, ensure compliance with such statutory requirements, rules, and regulations as may be applicable to the individual ship concerned.

Overview
ISO 6042:2015 - Ships and marine technology - Weathertight single-leaf steel doors - specifies the main dimensions, materials, manufacturing quality and weathertightness requirements for weathertight single-leaf steel doors used on board ships. The standard ensures interchangeability of door components while leaving detailed welding and some design choices to the manufacturer. It is aligned with the International Convention on Load Lines 1966 (ICLL66) and references ISO 3796 for clear opening sizes.
Key topics and technical requirements
- Scope & purpose: Defines principal dimensions, materials, and manufacturing conditions to achieve consistent, interchangeable marine doors.
- Door types and sizes: Defines coded door types (AB, FB, FBR, ABL, FBL, FBRL) and nominal sizes (height × width) in accordance with ISO 3796 for external single-leaf doors.
- Door frames and plates: Specifies frame profiles (angle/flat bar options), chamfering/rounding to protect seals, and internal plate dimensions to ensure correct fit.
- Fittings and arrangement: Location and number of clips, hinges, wedges, and retaining bars are standardized; clip counts are provided by nominal size to secure uniform sealing pressure.
- Door seal: Prescribes seal cross-section, bonding, retaining bar, and minimum compressed thickness (must not compress below 16 mm).
- Materials: Door plates/frames - weldable steel (min. 235 N/mm² yield or equivalent); clips, wedges, hinges lugs - weldable mild steel with minimum tensile strength; hinge pins - corrosion-resistant material. Sealing material must withstand marine conditions.
- Quality and finish: Requirements for distortion-free plates/frames, surface treatment (scale removal, priming), and no exposed rough edges.
- Weathertightness testing: Completed doors, once installed, must pass a hose test or equivalent acceptable to the regulatory authority.
- Designation: Standardized naming format (e.g., Door ISO 6042-FBR-1400×750) for non-installed doors.
Applications and users
ISO 6042:2015 is intended for:
- Shipbuilders and marine fabricators designing or supplying weathertight doors.
- Manufacturers of marine doors and hardware ensuring component interchangeability.
- Classification societies, marine surveyors, ship owners and operators verifying statutory compliance and installation.
- Naval architects and ship designers specifying deckhouse, superstructure and bulkhead access doors where ICLL66 compatibility is required.
Related standards
- ISO 3796 - Clear openings for external single-leaf doors (normative reference in ISO 6042).
- International Convention on Load Lines 1966 (ICLL66) - regulatory context for application positions and additional stiffening requirements.
Keywords: ISO 6042:2015, weathertight single-leaf steel doors, ships and marine technology, weathertight doors, marine doors, door frames, door seals, interchangeability, ICLL66.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
