EN 1765:2016 (E) 4 European foreword This document (EN 1765:2016) has been prepared by Technical Committee CEN/TC 218 “Rubber and plastics hoses and hose assemblies”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2017, and conflicting national standards shall be withdrawn at the latest by February 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1765:2004. Compared to EN 1765:2004 the following changes have been made: a) Clause 2: the normative references have been updated; b) Subclause 4.2: hose assemblies type S and L were subdivided into two grades Grade M (electrically bonded) and Grad

(electrically conductive); c) Subclause 5.2.3.2: one type of hose assembly assembled with hose nipples in accordance to EN 14420-2 and swaged or crimped ferrules has been added; d) Table 4: for the electrical properties (continuity) the maximum electrical resistance 106 per assembly for grade

was added; e) Clause 12: the requirements for marking have been amended. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 1765:2016

EN 1765:2016 (E) 5 Introduction This document specifies minimum requirements for the satisfactory performance of wire or textile reinforced rubber hose assemblies 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. Specific details of the construction of hoses are not rigidly defined in this document 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 allowance 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 pressure, which will depend on the severity of the user’s operating conditions and on the service life that is expected of the hose assembly. It is essential that the purchaser provides certain information about the hose assembly and its intended use at the time of enquiry and/or order; this information is 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). SIST EN 1765:2016

EN 1765:2016 (E) 6 1 Scope This European 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 containing a maximum aromatics content of 50 % (v/v). It is not suitable for liquefied petroleum gas and natural gas. Hose assemblies to this document can be used in the temperature range

«20 °C to 82 °C. The hoses specified are in the size range of nominal bore 50 to 500 and may be smooth bore, rough bore or armoured rough bore. Hoses for use with petroleum products having an aromatic content greater than 50 % (v/v) are outside the scope of this document but the requirements may be used as a basis for such hoses on request to the manufacturer. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

In no circumstances should more than one length of electrically discontinuous hose be used in an individual transfer pipeline and effective electrical continuity to earth from both ends of the electrically discontinuous hose should be maintained. 4.2 End – use Hose 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 stiff, 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 internal zinc coated steel wire helix there shall be external helical armour of a similar material. Type A hoses are electrically continuous and may 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 hose assemblies may be electrically continuous or electrically discontinuous (see Warning in 4.1); SIST EN 1765:2016

EN 1765:2016 (E) 8 Hoses and hose assemblies for this application shall be divided into two grades: — Grade M: electrically bonded; — Grade : electrically conductive; see EN ISO 8031:2009, Annex A for new recommended marking to indicate conductive lining, conductive cover or conductive lining and cover; — Type L, hose assemblies for dock service where greater flexibility, lower weight and ease of handling are of primary consideration. Type L hose assemblies may be electrically continuous or electrically discontinuous. They are only suitable for discharge applications (see Warning in 4.1); Hoses and hose assemblies for this application shall be divided into two grades: — Grade M: electrically bonded; — Grade : electrically conductive; see EN ISO 8031:2009, Annex A for new recommended marking to indicate conductive lining, conductive cover or conductive lining and cover. 4.3 Pressure ratings and designations Each type of hose assembly shall be designated according to the type letters R, A, S, or L followed by the maximum working pressure given in Table 1. For the purposes of this document the maximum working pressure includes an allowance for surge pressures above the normal operating pressure.

FprEN 1765:2015 (E) 4 European foreword This document (FprEN 1765:2015) has been prepared by Technical Committee CEN/TC 218 “Rubber and plastics hoses and hose assemblies”, the secretariat of which is held by BSI. This document is currently submitted to the Unique Acceptance Procedure. This document will supersede EN 1765:2004. Compared to EN 1765:2004 the following changes have been made: a) Clause 2: the normative references have been updated; b) Subclause 4.2: hose assemblies type S and L were subdivided into two grades Grade M (electrically bonded) and Grad

c) Subclause 5.2.3.2: one type of hose assembly assembled with hose nipples in accordance to EN 14420-2 and swaged or crimped ferrules has been added; d) Table 4: for the electrical properties (continuity) the maximum electrical resistance 106 per assembly

e) Clause 12: the requirements for marking have been amended. kSIST FprEN 1765:2016

FprEN 1765:2015 (E) 5 Introduction This document specifies minimum requirements for the satisfactory performance of wire or textile reinforced rubber hose assemblies 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. Specific details of the construction of hoses are not rigidly defined in this document 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 allowance 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 pressure, which will depend on the severity of the user’s operating conditions and on the service life that is expected of the hose assembly. It is essential that the purchaser provides certain information about the hose assembly and its intended use at the time of enquiry and/or order; this information is 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). kSIST FprEN 1765:2016

FprEN 1765:2015 (E) 6 1 Scope This draft European 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 containing a maximum aromatics content of 50 % (v/v). It is not suitable for liquefied petroleum gas and natural gas. Hose assemblies to this document can be used in the temperature range

«20 °C to 82 °C. The hoses specified are in the size range of nominal bore 50 to 500 and may be smooth bore, rough bore or armoured rough bore. Hoses for use with petroleum products having an aromatic content greater than 50 % (v/v) are outside the scope of this document but the requirements may be used as a basis for such hoses on request to the manufacturer. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

In no circumstances should more than one length of electrically discontinuous hose be used in an individual transfer pipeline and effective electrical continuity to earth from both ends of the electrically discontinuous hose should be maintained. 4.2 End – use Hose 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 stiff, 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 internal zinc coated steel wire helix there shall be external helical armour of a similar material. Type A hoses are electrically continuous and may 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 hose assemblies may be electrically continuous or electrically discontinuous (see Warning in 4.1); — Hoses and hose assemblies for this application shall be divided into two grades: kSIST FprEN 1765:2016
