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of an identical text or by endorsement, at the latest by July 2011, and conflicting national standards shall be withdrawn at the latest by July 2011 Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights This document supersedes EN 12115:1999 In comparison with EN 12115:1999 the following changes have been made: a) the test procedure to determine the electrical resistance through the hose wall is given in Annex A (normative); b) a list of hose lining material resistant to

Kingdom BS EN 12115:2011 EN 12115:2011 (E) Introduction This European Standard has been prepared to provide minimum acceptable requirements for the satisfactory performance of flexible rubber and thermoplastics hoses and hose assemblies with unspecified reinforcement and linings of different types of synthetic rubbers and thermoplastics, for each chemical substance conveyed A list of hose lining material resistant to specific chemical substances, identified by CAS number, has been added as Annex F (informative) This list is for information only BS EN 12115:2011 EN 12115:2011 (E) Scope This European Standard specifies requirements for two types of hose assemblies (Types D and SD) and four grades based on electrical properties with hoses made of rubber or thermoplastics and hose fittings made of metal designed to convey liquid or gaseous chemical substances, hereinafter termed the "chemicals conveyed" The hose assemblies are intended for use with chemicals conveyed in the temperature range of -20 °C to ) +65 °C at a working pressure ≤ 10 bar1 NOTE This European Standard sets out requirements for these hose assemblies to ensure that users are not exposed to danger from fire or explosion and that the environment is protected against contamination or damage NOTE Other temperatures and working pressures than those given above can be agreed with the manufacturer, provided that the marking on the hose (see 14.1) states this and the requirements of Table and all the other requirements are met NOTE Other diameters than those given in this European Standard can be agreed with the manufacturer NOTE This European Standard also provides guidance on the storage of hose assemblies (Clause 15) NOTE The attention of users is drawn to Annex F concerning the selection of lining material related to the chemical(s) to be conveyed by the hoses and/or hose assemblies This standard does not apply to hose assemblies for: aircraft refuelling (EN 1361); fuel dispensing (EN 1360); oil burners (EN ISO 6806); refrigerant circuits; fuel truck delivery (EN 1761); liquid petroleum gases (LPG) (EN 1762); fire fighting (EN ISO 14557); oil suction and discharge (EN 1765); rotary drilling (EN ISO 6807); fuel dispensing with vapour recovery system (EN 13483) This European Standard does not apply to multilayer hose assemblies (EN 13765 and EN 13766) 1) bar = 0,1 MPa BS EN
