19、d This document (EN 228:2012) 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
20、, either by publication of an identical text or by endorsement, at the latest by April 2013, and conflicting national standards shall be withdrawn at the latest by April 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN an
21、d/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 228:2008. This document was originally prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. In addition to other standards, it is
22、 intended to be complementary to the regulatory measures contained in various EU Directives. The following is a list of significant technical changes between this European Standard and the previous edition: New requirements following amendment 2009/30/EC 3 and 2011/63/EU 4 to the European Fuels Dire
23、ctive 98/70/EC 1, are taken into account. Tables 1, 2, 3, 4 and A.1 explicitly differentiate between requirements included in the European Fuels Directive 98/70/EC 1, including subsequent Amendments 2, 3 and 4, and other requirements. Specific requirements concerning the limitation of use of methylc
24、yclopentadienyl manganese tricarbonyl (MMT) as required by the EC have been incorporated. As the introduction of 10 % (V/V) of ethanol in unleaded petrol has an impact on refinery and blending processes, an update of the distillation characteristics has been considered and a new Table 3 with slightl
25、y adapted volatility classes (E70, E100 and VLI) has been introduced. Work is still ongoing to generate data that would support the idea that these changes do not affect cold starting and hot weather driveability aspects of the vehicles. These updates have been agreed upon with precaution and might
26、be revised depending on fuel-related issues in the market. Further specification is given, by including separate tables on unleaded petrol grade for older vehicles that are not warranted to use unleaded petrol with a high biofuel content. A CEN/TR aiming at giving guidance on oxygenate blending has
27、been prepared in parallel 5. Further clarification on how to determine the vapour pressure waiver for unleaded petrol containing ethanol, allowed on the market under exemption circumstances, is given in Annex A. The exact number of decimal points for the waiver has been clarified 4. Several new or r
28、evised test methods have been introduced. The European Fuels Directive 98/70/EC 1, including its Amendments 2 3 4, refers to test methods in EN 228:2004, with the requirement that updated analytical methods shall be shown to give at least the same accuracy and at least the same precision as the meth
29、ods they replace. Removal of the allowance for 50 mg/kg sulfur content. Reference to the revised ethanol specification EN 15376.

It is applicable to unleaded petrol for
33、 use in petrol engine vehicles designed to run on unleaded petrol. This European Standard specifies two types of unleaded petrol: one type with a maximum oxygen content of 3,7 % (m/m) and a maximum ethanol content of 10,0 % (V/V) in Table 1, and one type intended for older vehicles that are not warr
34、anted to use unleaded petrol with a high biofuel content, with a maximum oxygen content of 2,7 % (m/m) and a maximum ethanol content of 5,0 % (V/V) in Table 2. NOTE 1 The two types are based on European Directive requirements 3, 4. NOTE 2 For the purposes of this European Standard, the terms “% (m/m
35、)” and “% (V/V)” are used to represent respectively the mass fraction, , and the volume fraction, . 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
