CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes CEN/CWA 15293:2005. Significant tec
19、hnical changes between this European Standard and the CEN Workshop agreement are: the fuel requirements do allow the car manufacturers to optimize the ignition setting over the whole range of 0 % (V/V) to 85 % (V/V) of ethanol, whereas former limits of for instance vapour pressure and MON/RON were c
20、alculated on the basis of the percentage. This should give the user the benefit of the improved octane of the alcohol, even though some limits are set as indicative pending further field data; the requirements towards contaminants originating mainly from ethanol are aligned with the meanwhile publis
21、hed EN 15376. As alignment of units for elemental contaminants is pursued, a mean density value of 0,78 g/cm3has been used; the specification has been set to allow for the use of denatured and undenatured ethanol as a blending component, depending on national legislation; newly developed ethanol tes
22、t methods are used, which show a better applicability to Ethanol (E85) automotive fuel. Most of the test methods have been assessed for their effective applicability; the climate requirements do allow different percentages of ethanol to be blended, based on field experience, of which some limits are
23、 still under study. Furthermore, some of the determination methods referenced are still being investigated in terms of correct application and precision. This, and the fact that production processes need to be assessed on possibility to achieve the required or future limits, underlines the choice fo
24、r a CEN Technical Specification as an intermediate step. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estoni

39、es shall be taken as described in EN ISO 3170 or EN ISO 3171 and/or in accordance with the requirements of national standards or regulations for the sampling of Ethanol (E85) automotive fuel. The national requirements shall be set out in detail or shall be referred to by reference in a national anne
40、x to this European Standard. In view of the sensitivity of some of the test methods referred to in this European Standard, particular attention shall be paid to compliance with any guidance on sampling containers, which is sometimes included in the test method standard. It is essential that for samp
41、ling of Ethanol (E85) automotive fuel the containers used to take and store the samples before testing are free from any contamination. 4 Pump marking Information to be marked on dispensing pumps used for delivering Ethanol (E85) automotive fuel, and the dimensions of the mark shall be in accordance
42、 with the requirements of national standards or regulations for the marking of pumps for Ethanol (E85) automotive fuel. Such requirements shall be set out in detail or shall be referred to by reference in a national annex to this European Standard. NOTE The recommended designation for Ethanol (E85)
43、automotive fuel and its seasonal derivatives is “E85“.

44、rder to improve the performance quality the use of additives is allowed. Suitable fuel additives without known harmful side effects are recommended in the appropriate amount, to help to avoid deterioration of driveability and emissions control durability. Other technical means with equivalent effect
45、 may also be used. CAUTION Ethanol (E85) automotive fuel shall be free from any adulterant or contaminant that may render the fuel unacceptable for use in petrol engine vehicles designed to run on unleaded petrol and ethanol (E85) automotive fuel. NOTE Test methods for deposit forming tendency that
46、are suitable for routine control purposes have not yet been identified and developed. 5.3 Phosphorus In order to protect automotive catalyst systems, phosphorus containing additives shall not be used in Ethanol (E85) automotive fuel. 5.4 Denaturants The presence of petrol that conforms to EN 228 is
47、generally considered sufficient to render Ethanol (E85) automotive fuel a denatured product. If the presence of petrol is not recognized as a denaturant of ethanol by the relevant national authority, to avoid material compatibility issues with automotive engines and fuel systems, it is recommended t
48、o select denaturants from the list below that are known to be non harmful to vehicle systems: Ethyltertbutylether (ETBE); Methyltertbutylether (MTBE); Tertiary Butyl Alcohol (TBA); 2-methyl-1-propanol (isobutanol); and 2-propanol (isopropanol). The concentration of denaturant(s) is at the discretion
49、 of national authorities, but the final Ethanol (E85) automotive fuel shall still conform to the requirements as given in Table 1 and Table 2. NOTE The recommendations of ASTM D4806 4 regarding denaturants should be regarded. 5.5 Generally applicable requirements and test methods 5.5.1 Overall requirements Ethanol (E85) automotive fuel is a mixture o
