12、ent (EN 15376:2014) has been prepared by Technical Committee CEN/TC 19 “Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin”, the secretariat of which is held by NEN. This European Standard shall be given the status of a national standard, either b

13、y publication of an identical text or by endorsement, at the latest by April 2015 and conflicting national standards shall be withdrawn at the latest by April 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELE

14、C shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 15376:2011. This document has originally been prepared under mandate M/344 given to CEN by the European Commission and the European Free Trade Association along with other standards intended to

15、 be complementary to the regulatory measures contained in various EU Directives, see 1, 2, 3 and 4. If (bio)ethanol is meant for use as automotive fuel component, this document applies. It is intended to call up this European Standard in EN 228 5, in order to define the quality of (bio)ethanol which

16、 is added/blended to the petrol. The major updates of this third version concern the inclusion of newly developed methods for determination of inorganic chloride and sulfate, plus the lowering of their respective limits. As experience with ICP-OES instruments in the market has grown, EN 15837 has be

17、come the method in case of dispute for copper and sulfur content. The former version gave all relevant characteristics, requirements and test methods for (bio)ethanol, which were known at that time to be necessary to define the product to be used up to a maximum 10 % (V/V) blending component for aut

18、omotive petrol fuel. With the actual document, the percentage of use is expanded to allow use at all percentages up to and including 85 % (V/V) and the requirements are updated accordingly. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following count

19、ries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Pol

BS EN 15376:2014EN 15376:2014 (E) 4 1 Scope This European Standard specifies requirements and test methods for marketed and delivered ethanol to be used as an extender for automotive fuel for petro

21、l engine vehicles in accordance with the requirements of EN 228 5. It is applicable to ethanol used for blending at all levels up to and including 85 % (V/V). NOTE For the purposes of this document, the term “% (m/m)” and “% (V/V)” are used to represent the mass fraction, , and the volume fraction,

The national requirements shall be set out in detail or shall be referred to by reference in a national annex to this European Standard. In view of the sensitivity of some

31、 of the test methods referred to in this European Standard, particular attention shall be paid to compliance with any guidance on sampling containers included in the test method standard. 4 Requirements and test methods 4.1 Dyes and markers The use of dyes or markers is allowed. 4.2 Additives For di

32、stribution purposes, it is recommended that ethanol producers and downstream distributors and petrol blenders consider the need to add anti-corrosion additives to fuel grade ethanol. Suitable fuel additives without known harmful side effects and that are compatible with the finished petrol are recom

33、mended in the appropriate amount. These should not infringe patents through commingling. 4.3 Denaturing Denaturants, as required by European and national customs regulations are permitted, provided they do not cause harmful side effects to vehicles and petroleum distribution systems. Where denaturin

34、g of the automotive ethanol is required, it is strongly recommended to select denaturants from the list below that are known to be non-harmful to vehicle systems: automotive petrol conforming to EN 228, Ethyltertbutylether (ETBE), Methyltertbutylether (MTBE), Tertiary Butyl Alcohol (TBA), 2-methyl-1

35、-propanol (isobutanol) and 2-propanol (isopropanol). Any or all of these denaturants may be used alone or together, except isobutanol and isopropanol that are easily removed, so it is advisable to use them in combination with another denaturant. The concentration of denaturant(s) is at the discretio

36、n of national authorities and should not be in contradiction with EN 228 requirements. BS EN 15376:2014EN 15376:2014 (E) 6 4.4 Generally applicable requirements and related test methods 4.4.1 When tested by the methods indicated in Table 1, ethanol before denaturing shall be in accordance with the l

This method is considered too laborious for frequent testing, but it may be considered as a useful tool to determine cases where the audit trail approach is contested. BS
