BS EN 16865-2016 pdf free download.Inland navigation vessels — Connections and assembled hoses for the transfer of potable water.
This European standard specifies the design, dimensions and technical requirements for connections and pipelines for storing potable water for inland navigation vessels.
These are:
— a fixed connection on the supply side;
— pipeline;
— a fixed connection on the consumer side;
— a connection for retrofitting inland navigation vessels that have a closure device level with the deck (internal pipe thread pursuant to EN ISO 228-1), consisting of a connecting part with a threaded connection and fixed coupling.
Necessary measures to prevent electrostatic charge and overfilling are not governed by the standard.
National regulations apply to drinking water supply plants. The requirements of this European standard supplement these regulations.
