Description (English):

This document specifies a method using energy-dispersive X-ray fluorescence spectrometry 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 with sulfur content in the range of a mass fraction of 0,03 % to a mass fraction of 5,00 %. This test method can be used for biofuel or biofuel blends.

Abstract

Overview

ISO 8754:2025 - "Petroleum products - Determination of sulfur content - Energy-dispersive X-ray fluorescence spectrometry" specifies an EDXRF test method for measuring sulfur in a wide range of petroleum products and components. The method covers naphthas, unleaded motor gasolines, middle distillates, residual fuel oils, base lubricating oils and components, and is applicable to biofuel or biofuel blends. It applies to sulfur mass fractions from 0.03 % to 5.00 %. The standard replaces the 2003 edition and includes updates for matrix corrections and terms.

Key topics and technical requirements

Analytical technique: Energy-dispersive X‑ray fluorescence spectrometry (EDXRF) - excitation from an X‑ray tube or radioactive source; measurement of sulfur Kα radiation and conversion of counts to mass fraction by calibration.
Instrument essentials:
- X‑ray excitation with significant flux above 2.5 keV
- Removable sample cup with at least 3 mm sample depth and X‑ray transparent window film
- Detector sensitive at around 2.3 keV
- Filters or discrimination for sulfur Kα, pulse counting and pulse‑height analysis electronics
Reagents and standards:
- Low‑sulfur white oil diluent (preferably
