Overview
ISO 1751:2012 - Ships and marine technology - Ships’ side scuttles - defines standardized classification, dimensions and technical requirements for framed side scuttles fitted with thermally toughened safety glass panes. The standard covers interchangeability and construction details, materials, testing, marking and designation for side scuttles used on ships and is informed by SOLAS and Load Line conventions.
Key topics and technical requirements
- Classification: side scuttles are organized by series, type and model:
- Series N (regular) - uses thermally toughened glass per ISO 21005.
- Series P (fire‑resistant) - uses fire‑resistant panes complying with ISO 5797 and additional construction/testing requirements.
- Types A, B, C - heavy, medium and light constructions respectively.
- Models defined by opening/non‑opening, deadlight, opening direction and fastening (bolted or welded).
- Nominal sizes: clear light diameters standardized (200, 250, 300, 350, 400, 450 mm) for interchangeability.
- Dimensions & spigot heights: main dimensions and spigot recommendations are specified (e.g., bolted spigot ≈ 16 mm; welded spigot ≥ 30 mm).
- Glass fixing: standardized glass retaining frames - RFA (threaded), RFB and RFC (flanged) - and mounting details (screw thread M6, minimum length 16 mm, corrosion‑resistant materials).
- Materials: material classes for main frame, glassholder, retaining frame, hinges and fasteners; fire‑resistant series require materials retaining mechanical properties at elevated temperatures.
- Testing: includes board test, shop test, mechanical strength test and fire‑resistance test (where applicable). Annex A provides maximum allowable pressure limits for glass panes.
- Marking & designation: requirements for product marking and standardized designation formats to support survey and certification.
Practical applications
- Ensures interchangeability of marine windows across shipbuilders and suppliers.
- Supports compliance with SOLAS and load‑line safety regulations for passenger and merchant ships.
- Guides selection and procurement of side scuttles for newbuilds, refits and repairs - especially where fire‑resistant glazing or standardized replacement parts are required.
- Used in design documentation for accommodation, wheelhouse and other hull openings where side scuttles are installed.
Who should use ISO 1751:2012
- Ship designers and naval architects
- Shipbuilders and ship repair yards
- Window/side‑scuttle manufacturers and glass suppliers
- Classification societies, flag state surveyors and maritime inspectors
- Procurement and maintenance teams on commercial and passenger vessels
