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 [10].
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 draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 19.
If this draft becomes a European Standard, 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.
This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,

European foreword
This document (prEN 228:2024) 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 document is currently submitted to the CEN Enquiry.
This document will supersede 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:
— several new or revised test methods have been introduced. The European Fuels Quality Directive
98/70/EC [1], including its Amendments [2], [3], [4], [10] and [12] refer to test methods in
EN 228:2012, 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;
— introduction of the new clause “Terms and definitions”;
— correct use of the decimal point for Final Boiling Point (FBP) in limits has been implemented to align
with test method reporting requirements;
— update to 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;
— 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;
— introduction of EN 16270 as a method for high boiling components in unleaded petrol in 6.4;
— introduction of CEN/TR 17491 with 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 in 6.4;
— 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, 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, aiming at replacing EN 237 in the next revision;
— removal of reference to EN 238 and establishing of EN ISO 22854 as referee method for benzene
content;
— removal of reference to EN 16135;
— introduction of new GC-VUV test method, prEN 18015, for the determination of olefins, aromatics,
benzene, oxygen and oxygenates content.
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], [10], [12] and the Alternative Fuels
Infrastructure Directive [11] [provision for a reference to the AFIR that will supersede AFID – publication
is expected during autumn this year].
