Automotive fuels - Determination of manganese content in unleaded petrol - Inductively coupled plasma optical emission spectrometry (ICP OES) method
This European Standard specifies a method based on inductively coupled plasma optical emission spectrometry (ICP OES) for the determination of manganese content as methylcyclopentadienyl manganese tricarbonyl (MMT) in petrol from 2 mg/l to 8 mg/l. This test method is applicable to unleaded petrol containing up to 3,7 % (m/m) oxygen, including those with ethanol up to 10 % (V/V).
Kraftstoffe für Kraftfahrzeuge - Bestimmung des Mangangehalts in unverbleitem Ottokraftstoff - Optische Emissionsspektrometrie mit induktiv gekoppeltem Plasma (ICP OES)
Diese Europäische Norm legt ein Prüfverfahren für die Bestimmung des Mangangehaltes, angegeben als Methylcyclopentadienylmangantricarbonyl (MMT1)) in unverbleitem Ottokraftstoff im Bereich von etwa 2 mg/l bis etwa 8 mg/l fest. Die Bestimmung erfolgt mit Hilfe der optischen Emissionsspektrometrie mit induktiv gekoppeltem Plasma (ICP OES). Dieses Prüfverfahren gilt für unverbleiten Ottokraftstoff mit einem Sauerstoffgehalt von bis zu 3,7 % (m/m), einschließlich solcher Ottokraftstoffe, die bis zu 10 % (V/V) Ethanol enthalten. ANMERKUNG 1 Mangan als MMT wird Ottokraftstoff zur Verbesserung der Antiklopfeigenschaften zugesetzt. WARNUNG — Die Anwendung dieser Europäischen Norm kann den Einsatz gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Diese Europäische Norm gibt nicht vor, alle mit ihrer Anwendung verbundenen Sicherheitsprobleme anzusprechen. Der Anwender dieser Europäischen Norm ist dafür verantwortlich, vorher angemessene Maßnahmen im Hinblick auf Sicherheit und Gesundheit zu ergreifen und die Anwendbarkeit einschränkender Vorschriften zu ermitteln. ANMERKUNG 2 MMT-Lösungen in Ottokraftstoff sind unter Lichteinwirkung instabil. Niedrige und irrige Ergebnisse sind zu erwarten, wenn Proben vor der Analyse dem Licht ausgesetzt wurden. ANMERKUNG 3 Höhere Mangangehalte als 8 mg/l können nach vorhergehender Verdünnung der Probe mit einem zweckmäßigen Lösemittel gemessen werden. Für dieses Verfahren wurde jedoch keine Präzision bestimmt. ANMERKUNG 4 Die Anwendung zur Bestimmung anderer Manganverbindungen in unverbleitem Ottokraftstoff wurde nicht geprüft. ANMERKUNG 5 Für die Zwecke dieser Europäischen Norm wird zur Angabe des Massenanteils einer Substanz µ der Ausdruck „% (m/m)“ und für den Volumenanteil einer Substanz ϕ der Ausdruck „% (V/V)“ verwendet.
Carburants pour automobiles - Détermination de la teneur en manganèse dans les essences sans plomb - Méthode d'émission atomique à couplage inductif par plasma (ICP OES)
La présente Norme européenne spécifie une méthode spectrométrique optique par plasma à couplage
inductif (ICP OES) pour la détermination de la teneur en manganèse présent sous forme de
méthylcyclopentadiényl manganèse tricarbonyle (MMT1) dans l’essence sans plomb, de environ 2 mg/l à
environ 8 mg/l. Cette méthode d’essai est applicable aux essences sans plomb contenant jusqu’à 3,7 %
(m/m) d’oxygène, incluant celles contenant de l’éthanol à une teneur maximale de 10 % (V/V).
NOTE 1 Le manganèse sous forme de MMT est ajouté à l’essence afin d’en améliorer les propriétés antidétonantes.
AVERTISSEMENT — L'utilisation de la présente Norme peut impliquer l'intervention de produits,
d'opérations et d'équipements à caractère dangereux. La présente Norme 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.
NOTE 2 Les solutions de MMT dans l’essence sont instables en cas d’exposition à la lumière. Si les échantillons
d’essence sont exposés à la lumière avant l’analyse, les résultats attendus seront trop bas et inconstants.
NOTE 3 Les teneurs en manganèse supérieures à 8 mg/l peuvent être mesurées après dilution préalable de
l’échantillon avec un solvant approprié. Néanmoins la fidélité n’a pas été établie pour cette procédure.
NOTE 4 L’application de la méthode d’essai à la détermination d’autres composés de manganèse dans l’essence n’a
pas été testée.
NOTE 5 Pour les besoins de la présente Norme européenne, les expressions «% (m/m)» et «% (V/V)» représentent
respectivement les fractions massiques, µ, et volumiques, φ, du produit.

EN 16136:2011 (E) 4 1 Scope This European Standard specifies a method based on inductively coupled plasma optical emission spectrometry (ICP OES) for the determination of manganese content present as methylcyclopentadienyl manganese tricarbonyl (MMT 1)) in unleaded petrol from about 2 mg/l to about 8 mg/l. This test method is applicable to unleaded petrol containing up to 3,7 % (m/m) oxygen, including those with ethanol up to 10 % (V/V). NOTE 1 Manganese as MMT is added to petrol to increase anti-knock properties. WARNING — The use of this European Standard may involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. NOTE 2 Solutions of MMT in petrol are unstable when exposed to light. Low and erratic results are expected if petrol samples are exposed to light prior the analysis. NOTE 3 Manganese contents higher than 8 mg/l can be measured after preliminary dilution of the sample with a suitable solvent. However, the precision has not been established for such a procedure. NOTE 4 Application of the test method to the determination of other manganese compounds in petrol has not been tested. NOTE 5 For the purposes of this European Standard, the terms “% (m/m)” and “% (V/V)” are used to represent the mass fraction (µ) and the volume fraction (3) of a material respectively. 2 Normative references The following referenced documents are indispensable for the application of this document.

The solution is introduced directly into the plasma of an ICP OES spectrometer. Manganese content is calculated by comparison with calibration solutions prepared from suitable manganese compounds.
