EN 16865:2016 (E) DIN EN 16865:2016-12 5 Introduction This European standard has been developed to specify hygieni
23、cally perfect, standard pipelines and connections for the transfer and receipt of potable water on the supply side (bunker boats, onshore plant or similar) and the consumer side (inland navigation vessel). The connection consists of a pipe, a rapid coupling device both on the supply and consumer sid
24、e with appropriate dummy couplings. This will allow simple handling and secure transfer of potable water. Using this standard will prevent unsuitable pipes being used on the supply side and dirt getting into the potable water bunker on the consumer side by using pipes without couplings in openings t
25、hat are level with the deck. Dirt, micro-organisms and insects are prevented from penetrating by using dummy couplings on both sides. EN 16865:2016 (E) DIN EN 16865:2016-12 6 1 Scope This European standard specifies the design, dimensions and technical requirements for connections and pipelines for
26、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 22
27、8-1), 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
28、these regulations. 2 Normative references The following documents cited in whole or in part in this document are required for the application of this document.
