DIN EN 12115:2011-04 EN 12115:2011 (E) 5 Introduction This European Standard has been prepared to provide minimum acceptable requirements for the satisfactory performance of flexible rubber and the
26、rmoplastics 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 Ann
27、ex F (informative). This list is for information only. DIN EN 12115:2011-04 EN 12115:2011 (E) 6 1 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
28、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 1 This European Standard sets
29、 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 2 Other temperatures and working pressures than those given above can be agreed with the manufacturer, provide
30、d that the marking on the hose (see 14.1) states this and the requirements of Table 5 and all the other requirements 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
31、hose assemblies (Clause 15). NOTE 5 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 dispensin
32、g (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
33、 Standard does not apply to multilayer hose assemblies (EN 13765 and EN 13766). 1) 1 bar = 0,1 MPa.

DIN EN 12115:2011-04 EN 12115:2011 (E) 8 NOTE In this European Standard the word “fitting“ has been used; this is, in some cases, interchangeable with the
42、word “coupling“. 4 Classification Hoses and hose assemblies for this application shall be divided into two types, according 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 assemblie
43、s for this application shall be divided into four 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; Grade M/T: electrically bonded and with a
44、n electrical resistance through the hose wall not exceeding 109; Grade /T: electrically conductive and with an electrical resistance through the hose wall not exceeding 109. 5 Couplings and end fittings Hoses shall be fitted with end fittings and couplings to form hose assemblies. Examples are given
45、 in Annex C. 6 Materials and construction 6.1 General Hoses Type D shall consist of a lining, reinforcement and a cover. Hoses Type SD shall consist of a lining, reinforcement and a cover, and in addition incorporate one or more helixes. 6.2 Lining The lining shall be resistant to the chemical subst
46、ances conveyed. The lining shall be uniform in quality and thickness and shall be free from porosity, air holes, foreign inclusions and other defects which could impair the expected use. 6.3 Cover The cover shall be resistant to mechanical damage, wear and environmental effects due to weather and sh
47、ort-term chemical exposure. 6.4 Reinforcement The reinforcement shall consist of a textile material which is resistant to the medium conveyed.
