Foreword
This European Standard has been prepared by Technical Committee CEN/TC 218 'Rubber and plastic 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of an identical text or by endorsement, at the latest by March 1998, and conflicting national standards shall be withdrawn at the latest by March 1998.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
Introduction
This European Standard specifies minimum requirements for the satisfactory performance of wire 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 standard since it is felt that this could restrict the introduction of improved methods of construction. It should be noted that no reference is made to the hose assembly working pressure. Instead, the hose assemblies have been classified in terms of service pressure, which includes an allowance for surge pressure and which equates with the factory test pressure. It is the responsibility of the user to determine the appropriate working pressure, which depend on the severity of the user's 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 listed in annex A (informative). Recommendations concerning packaging and transportation are given in annex B (informative) and expected masses of hoses, in kilogramms per metre of free length, are given in annex C (informative).
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 40 % (v/v). It is not suitable for liquified petroleum gas and natural gas.
Hose assemblies to this European Standard can be used in the temperature range - 20 oC to 82 oC.
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. Rough bore hoses are not suitable for use with aviation fuels.
NOTE: Hoses for use with petroleum products having an aromatic content greater than 40 % (v/v) are outside the scope of this European Standard but the requirements may be used as a basis for such hoses on request to the manufacturer.
