Ethanol zur Verwendung als Blendkomponente in Ottokraftstoff - Bestimmung des Gehaltes an anorganischem Chlor und Sulfat - Ionenchromatographie
Diese Europäische Norm legt ein ionenchromatographisches Verfahren für die Bestimmung des anorga¬nischen Chlorgehaltes (Chlorid) in Ethanol im Bereich von 2,0 mg/l bis 25,0 mg/l und des Gehaltes an Sulfat in Ethanol im Bereich von 0,9 mg/l bis 15,0 mg/l fest.
ANMERKUNG Anorganische Chlorgehalte können von 0,8 mg/l bis 2,0 mg/l und Sulfatgehalte können von 0,4 mg/l bis 0,9 mg/l bestimmt werden. Trotzdem kann die Präzision dafür nicht angegeben werden, da entsprechende Proben mit Chlor und Sulfatgehalten aus diesen Bereichen nicht Teil des Ringversuchs waren.
WARNUNG — Die Anwendung dieser Europäischen Norm kann den Einsatz gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Diese Norm gibt nicht vor, alle mit ihrer Anwendung verbundenen Sicherheitsprobleme anzusprechen. Der Anwender dieser Norm ist dafür verantwortlich, vorher angemessene Maßnahmen zu ergreifen und die Anwendbarkeit einschränkender Vorschriften zu ermitteln.
Ethanol comme base de mélange à l'essence - Détermination de la teneur en chlorures minéraux et en sulfates - Méthode par chromatographie ionique
La présente Norme européenne prescrit une méthode de chromatographie ionique (IC) pour le dosage dans
l’éthanol des chlorures minéraux de 2,0 mg/l à 25,0 mg/l et des sulfates de 0,9 mg/l à 15,0 mg/l.
NOTE La teneur en chlorure minéral peut être déterminée de 0,8 mg/l à 2,0 mg/l, de même celle en sulfate de
0,4 mg/l à 0,9 mg/l. Cependant, la fidélité n’a pas été établie étant donné qu’il n’y avait dans l’essai interlaboratoires aucun
échantillon avec des teneurs en chlorures et en sulfates dans ces intervalles.
AVERTISSEMENT — L'utilisation de la présente Norme européenne peut impliquer l'intervention de
produits, d'opérations et d'équipements à caractère dangereux. La présente Norme européenne n'est
pas censée aborder tous les problèmes de sécurité concernés par son usage. Il est de la
responsabilité de l'utilisateur de consulter et d'établir des règles de sécurité et d'hygiène appropriées
et de déterminer l'applicabilité des restrictions réglementaires avant utilisation.

EN 15492:2008 (E) 3 Foreword This document (EN 15492:2008) 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 March 2009, and conflicting national standards shall be withdrawn at the latest by March 2009. 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 method described in this document is based on a method from a European Regulation on wine [1]. This method has been developed to suit the needs as expressed in the ethanol specification [2], also drafted by CEN/TC 19. This document supersedes EN 15492:2007.
The precision and the range of application for both inorganic chloride and sulfate have been updated based on a interlaboratory study done by CEN/TC 19/WG 27 on "Elemental analysis". Next, only the analytical water grade required has been updated according to general lab practice. 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 the United Kingdom.

EN 15492:2008 (E) 4 1 Scope This European Standard specifies an ion chromatographic (IC) method for the determination of the inorganic chloride content in ethanol from 2,0 mg/l to 25,0 mg/l and of the sulfate content in ethanol from 0,9 mg/l to 15,0 mg/l. NOTE Inorganic chloride content can be determined from 0,8 mg/l to 2,0 mg/l and sulfate content can be determined from 0,4 mg/l to 0,9 mg/l. However, the precision was not established as no samples with chloride and sulfate contents in these ranges where included in the interlaboratory test. WARNING — Use of this method may involve hazardous equipment, materials and operations. This method does not purport to address to all of the safety problems associated with its use, but it is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 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.

The dry residue is dissolved in water. The chloride and sulfate ion contents are determined by comparing the peak area in the chromatogram of the aqueous solution of the test portion with the curve of the calibration standards. The calibration standards are prepared from suitable compounds in aqueous solution. 4 Reagents Use only reagents of recognized analytical grade, such as “IC grade”, unless otherwise specified. 4.1 Sodium chloride (NaCl), MW 58,44 g/mol. 4.2 Sulfuric acid (H2SO4), solution at 0,1 mol/l, of which the concentration is verified by titration, or is certified in case of commercially available product. 4.3 Water, for analytical laboratory us
