Automotive fuels - Determination of content of butoxy-benzene in middle distillates - Gas chromatographic method using a flame ionization detector (GC-FID)
This document specifies a test method for the determination of the content of n-butyl phenyl ether (BPE, CAS: 1126-79-0, also known as butoxy-benzene) in gas oils, kerosene, diesel fuel and biodiesel blends. The method uses a two-column gas chromatograph with an FID-type of detector. The application range is 0,1 mg/l to 21,25 mg/l of BPE, with a limit of detection of 0,05 mg/l.
NOTE This corresponds to 1 % to 150 % of the average marking level of the ACCUTRACE™ Plus required by Commission Implementing Decision (EU) 2022/197 [1] of 17 January 2022 establishing a common fiscal marker for gas oils and kerosene.
The method is found to be applicable to determinations beyond this range or for specific other chemical markers that fall within the distillation temperature range of middle-distillates, but for that no precision has been determined.
WARNING - The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
Mineralölerzeugnisse - Bestimmung von Gehalt von Butoxybenzene in Mitteldestillaten – Gaschromatographisches Verfahren mit Flammenionisationsdetektor
Dieses Dokument legt ein Prüfverfahren für die Bestimmung des Gehalts an n-Butylphenylether (BPE, auch bekannt als Butoxybenzol) in Gasölen, Kerosin, Dieselkraftstoff und Biodieselmischungen fest. Bei dem Verfahren wird ein Zweisäulen-Gaschromatograph mit einem FID-Detektor verwendet. Der Anwendungsbereich reicht von 0,1 mg/l bis 21,25 mg/l BPE, mit einer Nachweisgrenze von 0,05 mg/l.
ANMERKUNG Das entspricht 1 % bis 150 % des vom Durchführungsbeschluss (EU) 2022/197 der Kommission [1] vom 17. Januar 2022 zur Bestimmung eines gemeinsamen Stoffes zur steuerlichen Kennzeichnung von Gasölen und Kerosin geforderten mittleren Gehalts an dem Kennzeichnungsstoff ACCUTRACETM PLUS.
Das Verfahren hat sich als anwendbar für Bestimmungen erwiesen, die über diesen Bereich hinausgehen, oder für bestimmte andere chemische Marker, die in den Destillationstemperaturbereich von Mitteldestillaten fallen, für die jedoch keine Präzision ermittelt wurde.
WARNUNG — Die Anwendung dieses Dokuments kann die Anwendung gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Dieses Dokument beansprucht nicht, alle damit verbundenen Sicherheitsprobleme zu behandeln. Es liegt in der Verantwortung der Person, die das Dokument anwendet, vor der Anwendung geeignete Maßnahmen für die Sicherheit und den Gesundheitsschutz zu ergreifen, und die Geltung einschränkender Vorschriften zu ermitteln.
Produits pétroliers - Détermination de la teneur de butoxybenzene dans les distillats moyens - Méthode par chromatographie gazeuse avec détecteur d'ionisation de flamme
Le présent document spécifie une méthode d'essai pour la détermination de la teneur en éther de n-butyl phényl (BPE, également connu sous le nom de butoxybenzène) dans les gazoles, le pétrole lampant, le carburant diesel et les mélanges de biodiesel. La méthode utilise un chromatographe en phase gazeuse à deux colonnes avec un détecteur de type DIF. Le domaine d'application est compris entre 0,1 mg/l et 21,25 mg/l de BPE, avec une limite de détection de 0,05 mg/l.
NOTE Cela correspond à une plage de 1 % à 150 % du niveau de marquage moyen de l'ACCUTRACE™ PLUS requis par la décision d'exécution (UE) 2022/197[1] de la Commission du 17 janvier 2022 établissant un marqueur fiscal commun pour les gazoles et le pétrole lampant.
La méthode s'avère applicable aux déterminations au-delà de cette fourchette ou pour d'autres marqueurs chimiques spécifiques qui se situent dans la fourchette de température de distillation des distillats moyens, mais pour lesquels aucune précision n'a été déterminée.

This document (EN 18051:2024) 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 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 June 2025, and conflicting national standards shall be
withdrawn at the latest by June 2025.
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 supports implementation in the market of the Decision [1] of the European Commission
with regards to common distillate fuel marking.
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
For the proper functioning of the internal market, the European Commission has established Directives
providing for a common marking system to identify gas oils and kerosene, which have been released for
consumption exempt from excise duty, or which are subject to a reduced excise duty rate. In a review in
2019, the Commission’s evaluation identified the shortcomings of the actual marker (Solvent Yellow 124)
in terms of its lack of resilience to common removal methods.
Consequently, a new, colourless chemical marker, Butoxybenzene (CAS Registry Number 1126-79-0),
was chosen to replace Solvent Yellow 124 as of 18 January 2024. This product or fiscal marker is
TM 1
commercially available as ACCUTRACE PLUS from DOW.
At the time of publication of the decision [1], a gas chromatography technique using a mass spectrometer
(GC-MS) as detector was promoted by DOW. That technique didn’t have a full precision. The first contacts
in 2022 with the European Commission and the EU Customs laboratories led CEN to conclude that the
GC-MS would not be further standardized.
This document has then been developed to present a simpler alternative to the market compared to the
GC-MS method.
The test method described in this document is based on a standard [2] previously prepared for a former
fuel marker, ACCUTRACE™ S101 (3-secbutyl-4-decyloxyphenylmethanetriyltribenzene), which is used in
a few European countries.
At the time of developing an interlaboratory study to determine method precision, the EU Customs
laboratories (CLEN) expressed the intention to also study an improvement of the GC-MS method. CLEN
and CEN used the same samples to develop precision. Bias against the ILIAD 606 method [3] has not been
determined.
Accutrace PLUS and ACCUTRACE S10 are the trade names of products supplied by DOW Chemicals. This
information is given for the convenience of users of this document and does not constitute an endorsement by CEN
of the product named. Equivalent products may be used.
1 Scope
This document specifies a test method for the determination of the content of n-butyl phenyl ether (BPE,
CAS: 1126-79-0, also known as butoxy-benzene) in gas oils, kerosene, diesel fuel and biodiesel blends.
The method uses a two-column gas chromatograph with an FID-type of detector. The application range
is 0,1 mg/l to 21,25 mg/l of BPE, with a limit of detection of 0,05 mg/l.
NOTE This corresponds to 1 % to 150 % of the average marking level of the ACCUTRACE™ Plus required by
Commission Implementing Decision (EU) 2022/197 [1] of 17 January 2022 establishing a common fiscal marker
for gas oils and kerosene.
The method is found to be applicable to determinations beyond this range or for specific other chemical
markers that fall within the distillation temperature range of middle-distillates, but for that no precision
has been determined.
