Overview
ISO 20884:2019/Amd 1:2021 is an amendment to the international standard for the determination of sulfur content in automotive fuels using wavelength-dispersive X-ray fluorescence (WD-XRF) spectrometry. This amendment specifically updates Table 1 of the standard by adding the Solid State Detector (SSD) to the monochromatic excitation section, enhancing the detection options for accurate sulfur measurement.
The ISO 20884 standard supports the petroleum industry by providing a reliable, standardized method for analyzing sulfur content, a critical parameter affecting fuel quality, emissions, and engine performance.
Key Topics
- Sulfur Content Determination: The core focus is on precise quantification of sulfur in automotive fuels, essential for regulatory compliance and environmental monitoring.
- Wavelength-Dispersive X-ray Fluorescence (WD-XRF): This analytical technique relies on measuring the fluorescent X-rays emitted by sulfur in fuel samples, enabling non-destructive and accurate sulfur analysis.
- Detector Technology: The amendment adds the SSD (Solid State Detector) as a recognized option alongside the traditional proportional counter with a pulse-height analyzer for monochromatic excitation setups.
- Monochromatic Excitation: Specific usage of monochromatic X-ray sources improves measurement sensitivity and accuracy; the inclusion of SSD technology further enhances this method.
- Standardization and Quality Assurance: Incorporates references to inter-laboratory studies and reports, reinforcing the method’s validation and repeatability.
Applications
- Automotive Fuel Quality Control: Ensures fuels meet sulfur content regulations, which vary globally but are crucial to reducing sulfur oxide emissions and protecting catalytic converters.
- Petroleum Refining: Refiners use the standard to monitor and adjust desulfurization processes.
- Environmental Compliance: Laboratories testing fuels for sulfur content to adhere to international emission standards.
- Research and Development: Enables development of cleaner fuel formulations by accurately detecting low sulfur concentrations.
- Regulatory Testing: Laboratory accreditation bodies and government regulators adopt this method for consistent sulfur content verification.
Related Standards
- ISO/TC 28 Standards: ISO 20884 is part of a broader portfolio of international standards related to petroleum products and fuel testing.
- CEN/TC 19 Collaboration: This amendment reflects cooperation between ISO and the European Committee for Standardization, harmonizing testing methods across regions.
- ISO/IEC Directives: The document follows ISO/IEC guidelines to ensure technical rigor and consistency in standard development.
- Other Petroleum Product Standards: Users often complement WD-XRF sulfur analysis with standards related to fuel properties such as density, composition, and contaminants to achieve comprehensive fuel characterization.
By updating ISO 20884 to include the SSD detector option, this amendment enhances analytical flexibility and accuracy in sulfur content determination of automotive fuels using WD-XRF spectrometry, facilitating stricter quality control and regulatory adherence in the petroleum sector.

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.
