BS EN 12115:2011EN 12115:2011 (E) 5 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

22、 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 12115:2011EN 12115:2011 (E) 6 1 Scope Thi

23、s 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 “ch

24、emicals 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 1 This European Standard sets out requirements for these hose assemblies to ensure that users are not exposed to danger from fire or exp

25、losion and that the environment is protected against contamination or damage. NOTE 2 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 5 and all the other req

26、uirements are met. NOTE 3 Other diameters than those given in this European Standard can be agreed with the manufacturer. NOTE 4 This European Standard also provides guidance on the storage of hose assemblies (Clause 15). NOTE 5 The attention of users is drawn to Annex F concerning the selection of

27、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 petrole

28、um 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).

38、ording to their duty requirements: Type D: hoses and hose assemblies for delivery duty only; Type SD: hoses and hose assemblies for suction and delivery duty. Hoses and hose assemblies for this application shall be divided into four grades: Grade M: electrically bonded; Grade : electrically conducti

39、ve; see EN ISO 8031:2009, Annex A for new recommended marking to indicate conductive lining, conductive cover or conductive lining and cover; Grade M/T: electrically bonded and with an electrical resistance through the hose wall not exceeding 109; Grade /T: electrically conductive and with an electr
