13、ion for Standardization) is a 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 h

14、as the right to be represented 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.The

15、procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the edi

16、torial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent ri

17、ghts identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.For an ex

19、cument is ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Rubber and plastics hoses and hose assemblies.This second edition of ISO 1823 cancels and replaces ISO 1823-1:1997 and ISO 1823-2:1997. Considering the actual market situations, two classes (the lowest and highest aromatics content)

20、 and one grade for maximum working pressure have been added in 4.3 and 4.4, respectively. ISO 2015 All rights reserved vBS ISO 1823:2015ISO 1823:2015(E)IntroductionThis International Standard specifies minimum requirements for the satisfactory performance of wire- or textile-reinforced rubber hose a

21、ssemblies of both smooth and rough bore types for oil suction and discharge services. The hoses are commonly used for transferring crude oil and liquid petroleum products, other than liquefied petroleum gas and natural gas, to and from tanker and bunkering vessels or for similar duties ashore.Specif

22、ic details of the construction of hoses are not rigidly defined in this International Standard since it is felt that this could restrict the introduction of improved methods of construction. The hose assemblies have been classified and designated in terms of service pressure, which includes an allow

23、ance for surge pressure and which equates to the factory test pressure. To keep this specification in line with other documents, this factory test pressure is also defined as the maximum working pressure (see Table 1). It is the responsibility of the user to determine the appropriate working pressur

24、e, which will depend on the severity of the users operating conditions and on the service life that is expected of the hose assembly.It is necessary for the purchaser to provide certain information about the hose assembly and its intended use at the time of enquiry and/or order; this information is

25、listed in Annex A (informative). Recommendations concerning packaging and transportation are given in Annex B (informative) and expected masses of hoses, in kilograms per metre of free length, are given in Annex C (informative).vi ISO 2015 All rights reservedBS ISO 1823:2015Rubber hose and hose asse

26、mblies for oil suction and discharge service Specification1 ScopeThis International Standard specifies the characteristics of four types of oil suction and discharge hose assemblies used for the conveyance of petroleum, including crude oils and other liquid petroleum products. Each type being divide

27、d into three classes depend on the aromatic contents. It is not suitable for liquefied petroleum gas and natural gas.Hose assemblies to this International Standard can be used in the temperature range 20 C to 80 C.The hoses specified are in the range of nominal size 50 to 500 and can be types of smo

28、oth bore, rough bore, armoured rough bore, and light weight.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

37、ARNING Careful consideration needs to be given before the use of electrically discontinuous hoses for transferring liquids known to generate static charges. In no circumstances should more than one length of electrically discontinuous hose be used in an individual transfer pipeline and effective ele

38、ctrical continuity to earth from both ends of the electrically discontinuous hose should be maintained.4.2 TypesHose assemblies for this application are classified according to end-use as follows: Type R, rough bore hose assemblies for dock operation and intended for situations where a relatively st

39、iff, heavy, and robust assembly can be used. The lining of the rubberized fabric is supported and reinforced by an internal (hot-dipped) zinc coated steel wire helix. Type R assemblies are electrically continuous; Type A, armoured rough bore hose assemblies for dock operation. In addition to an inte

40、rnal zinc coated steel wire helix, there shall be external helical armour of a similar material. Type A hoses are electrically continuous and can be lighter and more flexible than type R; Type S, smooth bore hose assemblies for dock operation where flexibility and lightness are important. Type S hos

41、e assemblies can be electrically continuous or electrically discontinuous (see Warning); Type L, hose assemblies for dock and general discharge service where greater flexibility, lower weight, and ease of handling are of primary consideration. Type L hose assemblies can be electrically continuous or

42、 electrically discontinuous. They are only suitable for discharge applications (see Warning).4.3 ClassesEach type of hose assemblies shall be designated according to three classes, depending on the conveyance of petroleum products containing the maximum aromatics content: Class 25: For oil and gasol

43、ine service (suitable for below 25 % aromatics content); Class 50: For oil and gasoline service (up to and including 50 % max. aromatics content); Class 100: For oil and gasoline service (suitable for up to 100 % aromatics content).NOTE For the determination of aromatics content, see ISO 3837.2 ISO
