Petroleum products - Determination of low concentration of sulfur in automotive fuels - Energy-dispersive X-ray fluorescence spectrometric method (ISO 13032:2012)
This European Standard specifies an energy dispersive X-ray fluorescence (EDXRF) test method for the determination of the sulfur content of automotive gasolines, including those containing up to 5 % (m/m) oxygen, and of automotive diesel fuels, including those containing up to 10 % (V/V) fatty acid methylester (FAME), having sulfur contents in the range 2 mg/kg to 50 mg/kg.
Other products may be analysed and other sulfur contents may be determined according to this test method, however, no precision data for products other than automotive fuels and for results outside the specified range have been established for this standard. For reasons of spectral overlap, this standard is not applicable to leaded automotive gasolines, lead replacement gasolines containing greater than 8 mg/kg lead, or to products and feedstocks containing lead, silicon, phosphorus, calcium, potassium or halides at concentrations greater than one tenth of the concentration of sulfur measured or more than 10 mg/kg, whichever is the greater.
Mineralölerzeugnisse - Bestimmung niedriger Schwefelgehalte in Kraftstoffen - Energiedispersives Röntgenfluoreszenzspektrometrieverfahren (ISO 13032:2012)
Diese Internationale Norm legt ein energiedispersives Röntgenfluoreszenzverfahren (edRFA) zur Bestimmung des Schwefelgehaltes im Bereich von 8 mg/kg bis 50 mg/kg in Ottokraftstoffen mit einem Sauerstoffgehalt von bis zu 3,7 % (m/m) (einschließlich von bis zu 10 % (V/V) Ethanol), sowie in Dieselkraftstoffen mit bis zu 10 % (V/V) Fettsäure-Methylester (FAME) fest. Andere Produkte auch mit anderen Schwefelgehalten können mit diesem Prüfverfahren ebenfalls untersucht werden; jedoch sind für andere als die hier genannten Kraftstoffe und Bereiche für den Schwefelgehalt keine Präzisionsangaben ermittelt worden. Wegen spektraler Überlagerungen ist das hier festgelegte Prüfverfahren nicht auf verbleite Ottokraftstoffe oder für Bleiersatzkraftstoffe mit Bleigehalten von mehr als 8 mg/kg einsetzbar. Das Prüfverfahren ist ebenfalls nicht auf Produkte oder Rohmaterialien anwendbar, die für die Elemente Blei, Silizium, Phosphor, Calcium, Kalium oder Halogenverbindungen Gehalte von mehr als 1/10 des gemessenen Schwefelgehaltes, oder aber mehr als 10 mg/kg aufweisen. ANMERKUNG Für die Zwecke dieser Internationalen Norm wird zur Angabe des Massenanteils einer Substanz der Ausdruck „% (m/m)“ und für den Volumenanteil einer Substanz der Ausdruck „% (V/V)“ verwendet.
Produits pétroliers - Détermination de la teneur en soufre en faible concentration dans les carburants pour automobiles - Méthode spectrométrique de fluorescence de rayons X dispersive en énergie (ISO 13032:2012)
L'ISO 13032:2012 spécifie une méthode d'essai par fluorescence de rayons X dispersive en énergie (FXDE) pour le dosage du soufre dans l'essence pour automobiles contenant jusqu'à 3,7 % (m/m) d'oxygène [y compris celle contenant de l'éthanol jusqu'à 10 % (V/V)], et dans les carburants diesels [y compris ceux contenant jusqu'à 10 % (V/V) d'esters méthyliques d'acide gras (EMAG)] ayant des teneurs en soufre comprises entre 8 mg/kg et 50 mg/kg.
D'autres produits peuvent être analysés et d'autres teneurs en soufre peuvent être déterminées suivant cette méthode; cependant, il n'a pas été établi de données de fidélité pour des produits autres que les carburants pour automobiles et pour des résultats en dehors du domaine spécifié pour l'ISO 13032:2012.
En raison de recouvrements spectraux, l'ISO 13032:2012 n'est pas applicable à l'essence pour automobiles contenant du plomb, ni à l'essence contenant un substitut de plomb dont la teneur en plomb est supérieure à 8 mg/kg, ni aux produits et charges contenant du plomb, du silicium, du phosphore, du calcium, du potassium ou des halogénures à des concentrations qui dépassent le dixième de la teneur en soufre mesurée, ou plus de 10 mg/kg, en choisissant la plus grande de ces valeurs.
Naftni proizvodi - Določevanje nizke koncentracije žvepla v gorivih za motorna vozila - Metoda z energijsko-disperzivno rentgensko fluorescenčno spektrometrijo (ISO 13032:2012)
Ta evropski standard določa preskusno metodo z energijsko-disperzivno rentgensko fluorescenčno spektrometrijo (EDXRF) za določanje vsebnosti žvepla v gorivih za motorna vozila, vključno s tistimi, ki vsebujejo do 5 % (m/m) kisika, in v dizelskih gorivih za motorna vozila, vključno s tistimi, ki vsebujejo do 10 % (V/V) metilnih estrov maščobnih kislin (FAME) in od 2 do 50 mg/kg žvepla.
Ta preskusna metoda se lahko uporablja za analizo drugih izdelkov in vsebnosti žvepla v drugih izdelkih, vendar za ta standard niso bili določeni podatki o natančnosti za izdelke, ki niso goriva za motorna vozila, in za rezultate zunaj določenega obsega. Zaradi prekrivanja spektra se ta standard ne uporablja za osvinčeni motorni bencin, bencin z nadomestkom svinca, ki vsebuje več kot 8 mg/kg svinca, ali za izdelke in surovine, ki vsebujejo svinec, silicij, fosfor, kalcij, kalij ali halide, katerih koncentracija je večja od ene desetine izmerjene koncentracije žvepla ali večja od 10 mg/kg, pri čemer se upošteva večja vrednost.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13032 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 19, Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological
origin, in collaboration with ISO Technical Committee TC 28, Petroleum products and lubricants, in accordance
with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

Introduction
This International Standard is directed specifically at the lower end of the concentration range covered in
[2]
ISO 20847 . By selecting the instrument type, a better signal-to-background ratio for sulfur K-L emission is
2,3
assured. A knowledge of the general composition of the sample for analysis is advantageous in obtaining the
best test result.
NOTE IUPAC X-ray line notation (S K-L ) is used in this International Standard; the corresponding Siegbahn X-ray
2,3
line notation (S-Ka) is being phased out.
Where matrix matching is not used and where the C:H mass ratio of the test sample is known or can be
determined, accuracy can be improved by the use of Equation (A.1) (see A.2.3) to correct the result to the
C:H mass ratio of the calibration standards, i.e. the reference diluent oil (see 4.1).
Some instruments include the capability for instrument-based matrix correction; notes on the use of this
approach to compensate for matrix effects in the test sample are provided in A.3 for information.

This International Standard is based on IP test method PM DU developed by the Energy Institute.
