Overview

SIST EN ISO 5620-2:2000 defines the essential technical requirements and component specifications for the filling connection of drinking water tanks on ships, focusing on the correct attachment of shipboard piping to land-based distribution systems or to another vessel. This European and international standard (identical to ISO 5620-2:1992) details the components - such as flanges, securing bolts, and gaskets - necessary for ensuring safe, sanitary, and reliable drinking water transfers in shipbuilding and marine structures.

This standard is part of a series governing drinking water filling connections and is indispensable for ship designers, marine engineers, and shipyard operators aiming to comply with international marine safety and hygiene regulations.

Key Topics

• Component Specifications
  Definition of main parts, including types and minimum material quality for:

  • Supply watering flange (flange A)
  • Ship watering flange (flange B)
  • Ship watering blind flange (flange C)
  • Securing bolts and nuts (including stud-bolts, hexagon bolts, and socket set screws)
  • Gaskets
  • Padlocks and securing chains

• Material Requirements

  • Flanges: Minimum of steel in accordance with ISO 630 grade Fe 360 or equivalent ship-quality steel
  • Bolts, nuts, and chains: Non-corrodible steel per ISO 683-1 grade H
  • Gaskets: Seawater-resistant elastomer suitable for potable water use
  • Padlocks: Non-corrodible metallic internal components (e.g., brass) for drinking water hygiene

• Designation and Marking
  Clear system for identifying each component per ISO 5620-2 to ensure compatibility and traceability during maintenance or inspection.

• Dimensional Standards
  Each component’s dimensions and surface texture must align with specified ISO references, ensuring system compatibility and ease of installation.

Applications

Practical Use Cases:

• Ship Construction and Retrofitting
  Ensuring new or refurbished vessels are equipped with internationally compliant drinking water filling connections.
• Marine Facility Upgrades
  Standardized connection points support easy and hygienic shore-to-ship or ship-to-ship potable water transfers.
• Safety and Hygiene Compliance
  Essential for regulatory inspections and maintaining crew and passenger health through safe water supply mechanisms.

Who Benefits:

• Shipbuilders
• Marine engineers & design consultants
• Ship operators
• Port authorities
• Marine regulatory bodies

Typical Scenarios:

• Installation and inspection of potable water systems aboard ocean-going vessels
• Maintenance of water supply connections in passenger and merchant ships
• Design and manufacturing of standardized marine piping and tank access equipment

Related Standards

For holistic compliance in marine potable water systems, consider these related standards:

• SIST EN ISO 5620-1: General requirements for filling connections for drinking water tanks
• ISO 630: Structural steels (material for flanges)
• ISO 683-1: Heat-treatable and alloy steels (material for bolts and chains)
• ISO 1302: Technical drawings - method of indicating surface texture
• ISO 2341: Clevis pins with head (alternative to securing bolts)
• ISO 4016: Hexagon head bolts - product grade C
• ISO 4026: Hexagon socket set screws with flat point

Summary

Adopting SIST EN ISO 5620-2:2000 ensures safe, compatible, and sanitary drinking water connections aboard marine vessels. By standardizing dimensions, materials, and component designations, shipbuilders and operators can achieve greater reliability, compliance, and operational efficiency in marine potable water systems. Compliance with this and related shipbuilding standards is critical to meet international marine safety, quality, and hygiene expectations.

Foreword
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. Esch 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, govern-
mental 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.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an Inter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard ISO 5620-2 was prepared by Technical Committee
ISWTC 8, Shipbuilding and marine structures.
This first edition of ISO 5620-2 together with ISO 56204 cancel and re-
place ttre first edition of ISO 5620, of which they constitute a technical
