Automotive fuels - Unleaded petrol - Requirements and test methods
This document specifies requirements and test methods for marketed and delivered unleaded petrol. It is applicable to unleaded petrol for use in petrol engine vehicles designed to run on unleaded petrol.
This document 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;
- one type in Table 2 with a maximum oxygen content of 2,7 % (m/m) and a maximum ethanol content of 5,0 % (V/V) intended for older vehicles that are not warranted to use unleaded petrol defined in Table 1.
NOTE 1 The two types are based on European Directive requirements [3], [4] and [13].
NOTE 2 For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction, µ, and the volume fraction, φ.

This European Standard was approved by CEN on 9 June 2025.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.

European foreword
This document (EN 228:2025) 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 by publication of an
identical text or by endorsement, at the latest by January 2026, and conflicting national standards shall
be withdrawn at the latest by January 2026.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 228:2012+A1:2017.
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 intended to be complementary
to the regulatory measures contained in various EU Directives.
The following is a list of significant technical changes between this document and the previous edition:
— introduction of the new clause “Terms and definitions”;
— update of the normative references towards undated versions where they don't concern
requirements originating from European Directives (in line with decisions by CEN/TC 19 in
coordination with the European Commission), and updating the effective publication dates where
required;
— introduction of several updated test methods in the tables. The European Fuels Quality Directive
98/70/EC [1], including its Amendments [2], [3], [4], [5], [6], [7] and [13] refer to test methods in
EN 228:2012+A1:2017, 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 methods they replace;
— deletion of the recommendation under 6.1 towards provision of evidence for the biological origin of
ethanol as this has now been fully covered by the (revised) EC Renewable Energy Directive;
— referencing under 6.4 of EN 16270 as a method for high boiling components in unleaded petrol;
— introduction under 6.4 of CEN/TR 17491 for further information on aniline, N-methyl aniline,
N-ethyl aniline, N,N di-methyl aniline and secondary-butyl acetate when used as blending
components in unleaded petrol;
— correct use of the decimal point for Final Boiling Point (FBP), distillation residue and existent gum
content in limits has been implemented to align with test method reporting requirements;
— clarification under 6.7.2 on how to address situations in which the test method includes a bias-
correction to the dispute method;
— introduction of the new EN ISO 4259-1 and EN ISO 4259-2 for the precision of measurement
methods and results, instead of the withdrawn EN ISO 4259;
— introduction of new test method for vapour pressure, EN 13016-3, and establishing method of
dispute as being EN 13016-1;
— introduction of a new micro-distillation test method, EN 17306, and establishing method of dispute
as being EN ISO 3405;
— change of method of dispute for content of benzene, oxygen and methanol to EN ISO 22854;
— introduction of EN 13723 as an additional analysis method for lead content and establishing method
of dispute as being EN 237, allowing an eventual change of the referee test method in the near future;
— removal of reference to EN 238 and establishing of EN ISO 22854 as referee method for benzene
content;
— removal of reference to EN 16135 as a method for the determination of manganese content;
— inclusion of new GC-VUV test method, EN 18015, for the determination of olefins, aromatics,
benzene, oxygen and oxygenates content;
— unification of distillation characteristics for E5 and E10 by lowering the E70 minimum values for E10
in Table 3 with 2 % V/V.
The marking at the pump of this product is in line with the requirements of the European Fuels Quality
Directive 98/70/EC [1], including its Amendments [2], [3], [4], [5], [6], [7] and [13] and the Alternative
Fuels Infrastructure Regulation [14].
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United
