Petroleum products - Determination of sulfur content - Energy-dispersive X-ray fluorescence spectrometry (ISO/DIS 8754:2025)
ISO 8754:2003 specifies a method for the determination of the sulfur content of petroleum products, such as naphthas, unleaded motor gasolines, middle distillates, residual fuel oils, base lubricating oils and components. The method is applicable to products having sulfur contents in the range 0,03 % (by mass) to 5,00 % (by mass).

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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO [had/had not] received notice of
(a) patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and 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 www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 28, Petroleum and related products, fuels and
lubricants from natural or synthetic sources.
This third edition cancels and replaces the second edition (ISO 8754:2003), which has been technically
revised.
The main changes are as follows:
— Scope: Expand scope to biofuel and biofuel blends without precision statement and describing procedures
for matrix corrections in Annex A.3.
— Add Clause 3 for Terms and definitions.
— Add Bibliography.
Any feedback or questions on this document should be directed to the user’s national standards body.

Introduction
A specialized procedure, using the analytical technique described in this International Standard, for
automotive fuels with sulfur contents below 0,20 % (m/m), have been developed. This can be found on the
ISO web page as ISO 13032:2024 - Petroleum and related products — Determination of low concentration of
sulfur in automotive fuels — Energy-dispersive X-ray fluorescence spectrometric method.
