Automotive fuels - Determination of methanol in automotive ethanol (E85) fuel by gas chromatography - Part 1: Method using single column technique

This European Standard specifies a method for the determination of methanol in automotive ethanol (E85) fuel by capillary gas chromatography using flame ionisation detection. The measurement range for the methanol is from about 0,1 % (m/m) to about 2,0 % (m/m), precision values were evaluated in the range from about 0,5 % (m/m) to about 1,5 % (m/m).

Kraftstoffe für Kraftfahrzeuge - Bestimmung von Methanol im automotive Ethanol (E85) als Kraftstoff durch Gaschromatographie - Teil 1: Gaschromatographisches Verfahren

Diese Europäische Norm legt ein Verfahren zur Bestimmung von Methanol in Ethanolkraftstoff (E85) für Kraftfahrzeuge (auch benannt als Ethanolkraftstoff (E85) oder kurz 'E85') mittels Kapillarsäulen-gaschromatographie mit Flammenionisationsdetektor fest. Spezifikationen zur Kraftstoffqualität für dieses Produkt sind vorhanden, siehe Literaturhinweis [1].
Der Messbereich für das Methanol reicht von etwa 0,5 % (V/V) bis etwa 1,5 % (V/V). Es können auch andere Methanolkonzentrationen bestimmt werden, jedoch liegen keine Präzisionsdaten für Ergebnisse außerhalb des festgelegten Bereichs vor.
ANMERKUNG   Für die Zwecke dieser Europäischen Norm werden die Begriffe '% (m/m)' und '% (V/V)' verwendet, um Massenanteile, μ, bzw. Volumenanteile, φ, anzugeben.
WARNUNG - Die Anwendung diese Norm kann die Anwendung gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Diese Norm beansprucht nicht, alle damit verbundenen Sicherheitsprobleme zu behandeln. Es liegt in der Verantwortung des Anwenders dieser Norm, vor ihrer Anwendung geeignete Maßnahmen für die Sicherheit und den Gesundheitsschutz des Personals zu ergreifen, und dafür Sorge zu tragen, dass behördliche und gesetzliche Maßnahmen eingehalten werden.

SIST EN 16761-1:2016

EN 16761-1:2015 (E) 3 European foreword This document (EN 16761-1:2015) 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of an identical text or by endorsement, at the latest by June 2016, and conflicting national standards shall be withdrawn at the latest by June 2016. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. The determination of a significant amount of methanol in ethanol (E85) automotive fuels was deemed to be necessary to check the product for compliance against EU emission regulations. The CEN/TC 19 Ethanol Fuels Task Force requested the development of such a determination technique. In EN 16761, Automotive fuels — Determination of methanol in automotive ethanol (E85) fuel by gas chromatography, two test methods were developed that comply with this scope: — Part 1: Method using single column technique [the present document]; — Part 2: Method using heart cut technique. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 16761-1:2016

EN 16761-1:2015 (E) 4 1 Scope This European Standard specifies a method for the determination of methanol in automotive ethanol (E85) fuel (also designated as ethanol (E85) automotive fuel or shortly "E85") by capillary gas chromatography using flame ionization detection. Fuel quality specifications for this product exist, see Bibliography Entry [1]. The measurement range for the methanol is from about 0,5 % (V/V) to about 1,5 % (V/V). Other methanol contents can also be determined, however no precision data for results outside the specified range is available. NOTE

For the purposes of this European Standard, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction, µ, and the volume fraction, . WARNING — The use of this standard can involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of users of this standard to take appropriate measures to ensure the safety and health of personnel prior to application of the standard, and fulfil statutory and regulatory requirements for this purpose. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
