18、s held by NEN. 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of an identical text or by endorsement, at the latest by April 2015 and conflicting national standards shall be withdrawn at the latest by April 2015. Attention is drawn to the possibility t
19、hat some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC 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 Eu
20、ropean Commission and the European Free Trade Association along with other standards intended to 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
21、call up this European Standard in EN 228 5, in order to define the quality of (bio)ethanol which 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 re
22、spective limits. As experience with ICP-OES instruments in the market has grown, EN 15837 has become 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
23、necessary to define the product to be used up to a maximum 10 % (V/V) blending component for automotive 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 t
24、he CEN-CENELEC Internal Regulations, the national standards organizations of the following countries 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,
25、Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. DIN EN 15376:2014-12 EN 15376:2014 (E) 4 1 Scope This European Standard specifies requirements and te
26、st methods for marketed and delivered ethanol to be used as an extender for automotive fuel for petrol 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,
27、the term “% (m/m)” and “% (V/V)” are used to represent the mass fraction, , and the volume fraction, , respectively. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

The national requirements shall be set out in detail or shall be
36、referred to by reference in a national annex 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 included in the test method standard. 4 Requ
37、irements and test methods 4.1 Dyes and markers The use of dyes or markers is allowed. 4.2 Additives For distribution 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 fu
38、el additives without known harmful side effects and that are compatible with the finished petrol are recommended 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, provi
39、ded they do not cause harmful side effects to vehicles and petroleum distribution systems. Where denaturing 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
40、 EN 228, Ethyltertbutylether (ETBE), Methyltertbutylether (MTBE), Tertiary Butyl Alcohol (TBA), 2-methyl-1-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
41、to use them in combination with another denaturant. The concentration of denaturant(s) is at the discretion of national authorities and should not be in contradiction with EN 228 requirements.

46、or identification of the biological origin of ethanol, a traceable record of biological origin is the recommended method. An alternative is age determination, which is based on the beta(minus) decay of the radioactive carbon isotope C-14 6. This method is considered too laborious for frequent testin

49、and interpretation of the results based on test method precision, described in EN ISO 4259, shall be used. 4.6.2 In cases of dispute concerning water content, EN 15489 shall be used. 4.6.3 In cases of dispute concerning copper or sulfur content, EN 15837 shall be used.
