16、. 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of an identical text or by endorsement, at the latest by October 1997, and conflicting national standards shall be withdrawn at the latest by October 1997. This standard is based on BS 3158 but the follo
17、wing major changes have been incorporated: six hose types reduced to four, omitting type A (non electrically bonded) and type D (non electrically bonded but incorporating an antistatic cover compound), which are no longer in regular use and are considered to be obsolete; maximum allowable fuel solub
18、le matter has been increased; minimum levels for adhesion between components have been increased; pressure ratings for all types have been standardized to the same requirements. A flammability test proposed by Germany has been included as an informative annex (annex A) so that experience in use and
19、values may be obtained prior to consideration for inclusion as a requirement. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece,

28、operations associated with the ground fuelling and defuelling of aircraft. All four types of hose are designed for: a) use with petroleum fuels, having an aromatic hydrocarbon content not exceeding 30 % by volume; b) operation within the temperature range of 230 C to +65 C and are to be undamaged by
29、 climatic conditions of 240 C to +70 C when stored in static conditions. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are l

35、 shall be one of the following four types, each incorporating an antistatic cover compound: a) type B, electrically conductive; b) type C, non-electrically conductive but incorporating an antistatic cover compound; c) type E, with enhanced defuelling capability (electrically conducting and incorpora
36、ting a metallic wire helix reinforcement); d) type F, with enhanced defuelling capability (non-electrically conducting and incorporating a non-metallic helix reinforcement with an antistatic cover). NOTE 1. Type C hoses are intended for general pressure application on all vehicles used for into-plan
37、e fuelling. It may also be used for vehicle/rail car loading and discharge where excessive vacuum does not occur. NOTE 2. Type F hoses may be used for into-plane delivery applications on vehicles that are also used for defuelling at high flow rates, and where type C hoses are not suitable. NOTE 3. T
38、ype E and type F hoses may also be used for vehicle/rail car loading and discharge, for trailer to fueller transfer, and for elevating platform supply (riser) to provide greater kink resistance. However, for riser application, a heavy duty type C hose or standard type C hose with an external wire sp
39、iral should be used when possible. This spiral should not be in electrical contact with the end couplings. 4.2 Service reeling diameter Hoses shall be designed for operation on equipment fitted with hose reels of the diameters given in table 1. NOTE. These hoses remain substantially circular in cros
40、s section when reeled on drums (see table 1) and should not be confused with hoses of the collapsible type that are intended to be reeled flat. Table 1.

Particulate type release agents shall not be used. The hose shall
44、be uniform in quality and free from porosity, air holes, foreign inclusions and other defects. The hose shall comprise: a lining of synthetic rubber resistant to petroleum fuel; a reinforcement of layers of woven, braided or spirally wound textile material; an outer cover of synthetic rubber, resist
45、ant to abrasion, outdoor exposure and petroleum fuel. The outer surface shall be uncorrugated and free from abrasive particles or ingredients which could scratch or mark aircraft surfaces. NOTE. The cover may have a shallow cloth marked finish. For type E and type F hoses only, an embedded helix rei
46、nforcement shall be included in the construction. For type E hoses the wire reinforcement used shall be a hard steel and shall have a galvanized finish. Construction relating to electrical properties are specified in clause 11. 6 Physical properties 6.1 Rubber compounds The physical properties of th
47、e rubber compounds used for the lining and cover shall comply with the values given in table 2, when tested by the methods listed in table 2. Tests shall be carried out either on samples taken from the hose or from separately vulcanized sheets, except for cold embrittlement and abrasion resistance t
48、ests which shall be carried out on moulded test pieces. 6.2 Finished hose The physical properties of the finished hose shall comply with the values given in table 3, when tested by the methods listed in table 3. 7 Pressure ratings 7.1 General For all types of hoses the following shall apply: maximum
49、 working pressure20 bar1); Proof pressure40 bar; minimum bursting pressure80 bar. NOTE. It is essential that the maximum pressure, including surge pressure to which the hose is subjected in service, does not exceed the permissible maximum working pressure specified. 7.2 Variation in length at maximum working pressure When tested in accordance with K.1.1, (see annex K), the maximum variation in length at maximum working pressure shall be 7 % of the original length for type B and type C hoses and 12
