ISO 5620 specifies the drinking water connection aboard ships for attachment of piping from another ship or from a land distribution system. This part of ISO 5620 specifies the general requirements, the composition and the designation of the complete filling connection and gives a recommendation for the installation aboard ships. NOTES 1 Details for the components of the filling connection are given in ISO 5620-2, both for the distribution system and for the ship. 2 The general rules for drinking water distribution systems fall within the competence of national port authorities and are outside the scope of ISO 5620. The connection specified in ISO 5620 safeguards drinking water tanks from being filled with any other fluid. Additionally it safeguards the supply piping of the drinking water from contamination by any other liquids. NOTES 3 ISO 5620 may be applied to inland vessels if agreed between the users. 4 Users of ISO 5620 should note that, while observing the requirements of the standard, they should at the same time ensure compliance with such statutary requirements, rules and regulations as may apply to the individual ship concerned.
