Overview

EN ISO 5620-2:1996 (ISO 5620-2:1992) specifies the technical details and designation of the main components used in shipboard drinking-water filling connections. This part covers the individual elements required for attachment of piping or hoses from another ship or a shore distribution system, focusing on material selection, designation conventions and referenced manufacturing details.

Key elements described include supply and ship watering flanges, blind flanges, securing bolts and studs, gaskets, nuts, padlocks and securing chains. Surface texture and finish requirements are referenced to ISO 1302, and material grades are defined by referenced steel standards.

Key Topics

Component scope and designation

Flanges are designated by type: Flange ISO 5620-2 - A (supply), - B (ship), - C (blind).
Other components use code letters (for example Bolt ISO 5620-2 - D, Gasket ISO 5620-2 - E).

Materials and corrosion resistance

Flanges: steel to ISO 630, minimum grade Fe 360; ship-quality plate grade A may be used if equivalent.
Fasteners (securing bolts, stud-bolts, nuts): non-corrodible steel, minimum grade H in accordance with ISO 683-1.
Gaskets: seawater-resistant elastomer suitable for drinking water service.
Padlock internals: non-corrodible metallic materials (e.g., brass); other parts may be steel.

Dimensional and finish requirements

Detailed dimensions for each component are given in the standard figures (supply/ship/blind flanges, gasket, securing bolt).
Surface texture requirements are referenced to ISO 1302.

Associated hardware

Securing chains: non-corrodible chain with an S-shaped hook and securing ring for padlock connection; common small chains without special quality requirements may be used.
Nuts: hexagon cap nuts M16 (or ordinary hexagon nuts of equivalent material) are specified.

Applications

Ensuring compatible ship-to-ship and ship-to-shore drinking-water transfer connections by standardising component dimensions and materials.

Supporting shipyards, naval architects and maintenance teams in selecting and specifying approved components for potable-water systems aboard vessels.

Reducing contamination and corrosion risks by mandating non-corrodible materials and potable-water compatible gasket materials.

Related Standards

ISO 5620-1: General requirements for filling connections (complements Part 2 by covering assembly and overall requirements).

ISO 5620 (series): Part 1 (general requirements) and Part 2 (components).

Referenced normative standards included in the text: ISO 630 (structural steels), ISO 1302 (surface texture), ISO 683-1 (steel grades), ISO 2341 (clevis pins), ISO 4016 (hexagon head bolts), ISO 4026 (hexagon socket set screws).

For procurement and specification, use the designations given in EN ISO 5620-2 and confirm dimensional details and surface finish from the figures and referenced ISO documents to ensure interoperability and safe marine water transfer.
