Petroleum and related products - Determination of low concentration of sulfur in automotive fuels - Energy-dispersive X-ray fluorescence spectrometric method (ISO 13032:2024)
This document specifies an energy dispersive X-ray fluorescence (EDXRF) test method for the determination of sulfur content in automotive fuels. This document is applicable to:
— gasoline containing up to 3,7 % oxygen by mass (including those blended with ethanol up to 10 % by volume) having sulfur contents in the range of 6,9 mg/kg to 56,7 mg/kg,
— diesel fuels including those containing up to about 30 % fatty acid methyl ester (FAME) by volume, paraffinic diesel fuel, and neat FAME, having sulfur contents in the range of 5,0 mg/kg to 60,2 mg/kg.
The sulfur content in other products can be determined according to the test method specified in this document; however, no precision data for products other than automotive fuels and for results outside the specified range have been established for this document.
For reasons of spectral overlap, this document is not applicable to leaded automotive gasoline, gasoline having a content of greater than 8 mg/kg lead or to product and feedstock 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.

Le présent document spécifie une méthode d'essai par fluorescence de rayons X dispersive en énergie (FXDE) pour le dosage du soufre dans les carburants automobiles. Le présent document est applicable:
— à l’essence pour automobiles contenant jusqu'à 3,7 % en masse d’oxygène [y compris celle contenant de l’éthanol jusqu’à 10 % en volume] et ayant une teneur en soufre comprise entre 6,9 mg/kg et 56,7 mg/kg,
— aux gazoles, y compris ceux contenant jusqu'à 30 % en volume d'esters méthyliques d'acide gras (EMAG), aux gazoles paraffiniques, et aux EMAG purs ayant des teneurs en soufre comprises entre 5,0 mg/kg et 60,2 mg/kg.
La teneur en soufre dans d'autres produits peut être déterminée suivant la méthode d’essai spécifiée dans le présent document; 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 le présent document.
En raison de recouvrements spectraux, le présent document n'est pas applicable à l’essence pour automobiles contenant du plomb, ni à l’essence contenant du plomb à une teneur 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.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 28, Petroleum and related products, fuels
and lubricants from natural or synthetic sources, in collaboration with CEN/TC 19, Gaseous and liquid
fuels, lubricants and related products of petroleum, synthetic and biological origin.
This second edition cancels and replaces the first edition (ISO 13032:2012), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— extension of the Scope to include hydrotreated vegetable oil (HVO), synthetic fuel Gas To Liquid
(GTL) and neat fatty acid methyl ester (FAME);
— update of the precision details.
Any feedback or questions on this document should be directed to the user’s national standards body. A

assured. A knowledge of the general composition of the sample for analysis is advantageous in obtaining
the best test result. Compared to the previous version new fuels have been added to the scope. In
addition, the precision and bias statements as well as the concentration range were updated based on
results of a new interlaboratory study. This has been done for gasoline an
