Automotive fuels - Paraffinic diesel fuel from synthesis or hydrotreatment - Requirements and test methods

This document describes requirements and test methods for paraffinic diesel fuel marketed and delivered as such, containing a level of up to 7,0 % (V/V) fatty acid methyl ester (FAME). It is applicable to fuel for use in diesel engines and vehicles compatible with paraffinic diesel fuel. It specifies two classes of paraffinic diesel fuel: high cetane and normal cetane.
Paraffinic diesel fuel originates from synthesis or hydrotreatment processes.
NOTE 1   For general diesel engine warranty, the vehicle manufacturer needs to be consulted before use. Paraffinic automotive diesel fuel may need a validation step to confirm the compatibility of the fuel with the vehicle, which for some existing engines may still need to be done (see also the Introduction to this document). However, it is noted that paraffinic diesel fuel is extensively available and has been increasingly approved by vehicle manufacturers for usage in vehicles since the first publication of this document.
NOTE 2   For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction and the volume fraction.

In this document, all relevant characteristics, requirements and test methods are specified. These
specifications are relevant for the driveability of the vehicles and are currently known to prevent harm
to the vehicles and their powertrains. Climate dependent requirements of this document may vary
according to national adoptions of EN 590 and EN 14214, and should be indicated by a specific National
Annex.
Requirements following amendment 2003/17/EC [11], 2009/30/EC [12], 2011/63/EU [13] and
2014/77/EU [14] to the European Fuels Quality Directive 98/70/EC [10], are taken into account. Dates
are included with all normative test method references in order to comply with the requirements of the
European Commission; with the accompanying assurance by CEN/TC 19 that any referenced updated
versions will always give at least the same accuracy and at least the same level of precision (see [12]).
The marking at the pump of this product is in line with the requirements of the Fuels Quality Directive
and the Alternative Fuels Infrastructure Directive [15].
Several assessments of test methods for paraffinic diesel fuel have been executed and the results thereof
[8] led to conclusions regarding the applicability of each of the test methods as required in Clause 6. The
conclusion of these assessments, partially funded by the European Commission, led to the possibility to
upgrade the original Technical Specification into a full European Standard. Although it is its main actual
use, the product is now no longer limited to captive fleet usage, but the scope defines the need to check
the use of the product with the vehicle manufacturer. There are no EU legislative needs to limit the
product to captive fleets. Such restriction is not for the specification but for the market to decide upon.
Therefore, and in the light of the need to check the use of the product with the vehicle manufacturer, all
restrictions towards captive fleet from the CEN/TS text have been deleted.
This document is based on current knowledge at the time of publishing, but will require review based on
further experiences with the use of paraffinic diesel fuel or when the specification for either regular
automotive diesel fuel, EN 590, or FAME, EN 14214, has been determined (revised) by CEN/TC 19 or
based on further experiences with the use of paraffinic diesel fuel according to this document. Further
background can be found in CEN/TR 16389 [4].
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
Kingdom.
Introduction
This document has been laid down to specify a standard with requirements for diesel fuel on the basis of
synthesis gas or of hydrotreated bio-oils, –fats or other suitable feedstock. Paraffinic diesel fuel does not
meet the automotive diesel fuel standard, EN 590 [1]. Its density can be outside the limits for automotive
diesel fuel, and the described class A type fuel has a higher cetane number. Paraffinic diesel fuel is
extensively available and has been increasingly approved for usage in vehicles since the first publication
of EN 15940. However it is not released for all vehicles, consult vehicle manufacturer before use.
As some production processes result in a fuel containing cyclo-paraffins, as well as n-paraffins and iso-
paraffins, they show different cetane number compared to other paraffinic diesel fuels. Hence, in this
document, two classes have been specified, one class showing improved ignition quality compared to
automotive diesel fuel meeting EN 590.
Blending of paraffinic diesel fuel with fatty acid methyl ester (FAME) is covered in this document. Against
the background of the EU Renewable Energy Directive (RED, 2018/2001/EC [9]) and also the latest
developments regarding the European automotive diesel fuel standard, there is now a pressing
requirement to allow for FAME blend variations of those paraffinic fuels, which are not already classified
as being from renewable resources.
Paraffinic diesel fuel is also used as a blending component in automotive diesel fuel. In that case it does
not have to meet EN 15940 requirements since composition and properties of diesel fuel blends are
specified in the respective automotive diesel fuel standards, e.g. EN 590 and EN 16734 (see EN 590:2022,
6.4 and EN 16734:2022, 6.4 [3]).
The document will be usable on a voluntary basis for engine clearance, fuel a
