This document specifies a wavelength-dispersive X-ray fluorescence (WDXRF) test method for the determination of the sulfur content of ethanol from 7 mg/kg to 20 mg/kg.
NOTE   For the purposes of this European Standard, the term "% (m/m)" is used to represent the mass fraction of a material.

Ethanol zur Verwendung als Blendkomponente in Ottokraftstoff - Bestimmung des Schwefelgehaltes - Wellenlängendispersive Röntgenfluoreszenz-Spektrometrie (wdRFA)

Diese Norm gilt für die Bestimmung des Schwefelgehaltes in Ethanol mit Hilfe er wellenlängendispersiven Röntgenfluoreszenz-Analyse (wdRFA) im Bereich von 7 mg/kg bis 20 mg/kg.
ANMERKUNG   Für die Zwecke der vorliegenden Internationalen Norm ist unter "% (m/m)" der Massenanteil in Prozent einer Substanz zu verstehen.

Éthanol comme base de mélange a l'essence - Dosage du soufre - Méthode de fluorescence de rayon X dispersive en longueur d'onde

Le présent document prescrit une méthode d’essai par fluorescence de rayons X dispersive en longueur d’onde
(FXDLO) pour le dosage du soufre dans l’éthanol pour des teneurs comprises entre 7 mg/kg et 20 mg/kg.
NOTE Pour les besoins de la présente Norme européenne l’expression "% (m/m)" est utilisée pour désigner la fraction
massique d'un produit.

EN 15485:2007 (E) 3 Foreword This document (EN 15485:2007) 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of an identical text or by endorsement, at the latest by February 2008, and conflicting national standards shall be withdrawn at the latest by February 2008. The method described in this document is based on EN ISO 20884 [1]. 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, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

NOTE For the purposes of this European Standard, the term "% (m/m)" is used to represent the mass fraction of a material. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 3170, Petroleum liquids — Manual sampling (ISO 3170:2004) 3 Principle The sample under analysis is exposed in a sample cell to the primary radiation of an X-ray tube. The count rates of the S-Kα X-ray fluorescence and the count rate of the background radiation are measured. The sulfur content of the sample is determined from a calibration curve defined for the relevant measuring range. NOTE Whilst the Siegbahn X-ray line notation (S-Kα) is used in this document, the corresponding IUPAC X-ray line notation is S K-L2,3. 4 Reagents and materials 4.1 Dibutylsulfide, of nominal sulfur content 21,92 % (m/m), or
