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.

3 Terms and definitions
The following terms apply to the application of this document.
3.1 potable water
Water for human consumption as specified in Council Directive 98/83/EG (see [8])
[SOURCE: EN 13443-2:2005+A1:2007, 3.12]
3.2 pipeline
Pipe with a pipe connection on both sides or with a pipe connection on one side and a fixed connection on the other side
3.3 pipe connector
Pipeline fitting consisting of a pipe clamp, a pipe coupling and a dummy coupling
3.4 fixed connection
A permanently installed fitting consisting of a threaded pipe connection, fixed coupling and dummy coupling
4 Technical requirements
4.1 General information
General tolerances: ISO 2768— c
The requirements relate to the design, dimensions and configuration of the connections.
4.2 Components
4.2.1 General information
The position of the connection and the dimensions and specifications as set out under Paragraph 4 – Paragraph 7 shall be observed for the connection.
On the supply side, there are the following versions:
— Fixed connection to connect a pipeline;
— Permanently connected pipeline.
On the consumer side there are the following versions:
— Fixed connection;
— Retrofitting connection.
The overviews in Figure 1 and Figure 2 provide examples of connections for storing potable water.
4.2.2 Fixed connection
4.2.2.1 General information
The fixed connection, see Figure 3, shall consist of a threaded pipe connection, a C coupling with dimensions as per DIN 14307-1 as a fixed coupling and a dummy coupling.
4.2.2.2 Fixed connection on the supply side
The C coupling on the supply side, 4.2.2.1, shall be permanently connected to the threaded pipe connection.
4.2.2.3 Fixed connection on the consumer side
The C coupling on the consumer side, 4.2.2.1, shall be permanently connected to a threaded pipe connection. The pipe shall be fitted with an ISO 228 – G 2 A pipe thread 20 mm long (DN 50). The pipe connection shall be welded firmly to the superstructure, the deck or the pipeline system and in such a way that its end is at least 300 mm above the deck. The C coupling shall be permanently attached to the pipe connection.BS EN 16865 pdf download.
