It is identical with ISO 5620-1:1992 published by the International Organization for Standardization. It supersede
7、s BS MA 85:1979 which is withdrawn. EN ISO5620-1:1996 was produced as a result of international discussions in which the United Kingdom took an active part. Cross-references The British Standards corresponding to the European Standards referred to in the text are identical in number and title with t
8、hose given in annex ZA. The Technical Committee has reviewed the provisions of ISO1461:1973, to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A British Standard does not purport to include all the necessary provisions of a co
9、ntract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

23、worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented
24、 on that committee. International organizations, governmental 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 ado
25、pted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 5620-1 was prepared by Technical Committee ISO/TC 8, Shipbuilding and marine st
26、ructures. This first edition of ISO5620-1 together with ISO5620-2 cancel and replace the first edition of ISO5620, of which they constitute a technical revision. ISO 5620 consists of the following parts, under the general title Shipbuilding and marine structures Filling connection for drinking water
27、 tanks: Part 1: General requirements; Part 2: Components. Descriptors: Shipbuilding, ships, water supply, potable water, tanks (containers), piping, water pipelines, pipe joints, connecting joints, specifications, dimensions, designation, installation.iv blankENISO5620-1:1996 BSI 12-1998 1 1 Scope I
28、SO5620 specifies the drinking water connection aboard ships for attachment of piping from another ship or from a land distribution system. This part of ISO5620 specifies the general requirements, the composition and the designation of the complete filling connection and gives a recommendation for th
29、e installation aboard ships. NOTE 1Details for the components of the filling connection are given in ISO5620-2, both for the distribution system and for the ship. NOTE 2The general rules for drinking water distribution systems fall within the competence of national port authorities and are outside t
30、he scope of ISO5620. The connection specified in ISO5620 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. NOTE 3ISO5620 may be applied to inland vessels if agreed betwee
31、n the users. NOTE 4Users of ISO5620 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. 2 Normative references The following standards
32、 contain provisions which, through reference in this text, constitute provisions of this part of ISO5620. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO5620 are encouraged to investigate the po
33、ssibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

A flange fitted to the ship piping (flange B inFigure 1) and a second one (flange A) to the pipin
35、g or hose line from the drinking water supply source, at which the ship watering flange (B) has a blind flange (C). 3.2 Flange connection 3.2.1 The watering flanges A, B and C shall have a special five-point connection in accordance with the dimensions given inFigure 2. 3.2.2 The nominal diameter of
36、 flange connections and piping shall be DN 65. 3.2.3 The nominal pressure of flange connections and piping shall be PN 16. 3.3 Securing of connection and main dimensions To prevent unauthorized access to the connection on the ship, the blind flange (C) shall be secured by a corrosion-resistant padlo
37、ck which is fitted to a securing bolt at the lower part of the connection, as shown inFigure 3. 3.4 Sealing A gasket of suitable material for drinking water systems shall be fitted to the ship watering flange(B). 3.5 Materials and finish 3.5.1 The flange connection shall be made of weldable steel wi
38、th a tensile strength of at least360MPa (360 N/mm 2 ). 3.5.2 Corrosion protection shall be obtained by hot galvanizing in accordance with ISO1461 or by other coating which does not constitute a health hazard. 4 Composition The composition (code letter Z) of the ship piping connection shall be as giv
39、en inFigure 3 consisting of components as listed inTable 1. For details of components, see ISO5620-2. The stud-bolt (serial No. 5) and the securing bolt (serial No. 3) shall be spot-welded or fastened by means of suitable adhesive into the ship watering flange (serial No. 1).ENISO5620-1:1997 2 BSI 1
