Full title and description

St ISO 20847-2004 (Ст ISO 20847-2004) — Petroleum products — Determination of sulfur content of automotive fuels — Energy‑dispersive X‑ray fluorescence spectrometry. The document specifies an energy‑dispersive X‑ray fluorescence (EDXRF) test method for determining total sulfur in automotive gasoline and diesel fuel matrices; a Russian-language edition/translation (rus) of the ISO text is available.

Abstract

ISO 20847:2004 describes an EDXRF procedure to determine sulfur in motor gasolines (including fuels with up to 2.7 % m/m oxygen) and in diesel fuels (including blends containing up to 5 % V/V fatty acid methyl esters, FAME) for sulfur contents nominally in the range 30 mg/kg to 500 mg/kg. The method notes limitations (no precision data outside the stated range) and specific interferences (e.g., leaded gasolines and samples with significant concentrations of lead, silicon, phosphorus, calcium, potassium or halides).

Scope

The standard applies an energy‑dispersive X‑ray fluorescence spectrometric technique for determination of total sulfur in automotive gasoline and diesel fuel matrices within the specified concentration interval (approximately 30 mg/kg to 500 mg/kg). It is intended for homogeneous liquid samples; precision statements are given only for the specified fuel types and concentration range. The method is not applicable to leaded motor gasolines or to samples containing interfering elements (lead, silicon, phosphorus, calcium, potassium or halides) at concentrations greater than about one‑tenth of the sulfur concentration being measured.

Key topics and requirements

• Analytical technique: energy‑dispersive X‑ray fluorescence (EDXRF) for total sulfur quantification.
• Applicable matrices: motor gasolines (O2 ≤ 2.7 % m/m) and diesel fuels (FAME ≤ 5 % V/V) within the stated sulfur range.
• Calibration and reference materials: requirements for calibration procedures and use of suitable reference materials to ensure accuracy.
• Performance/precision: precision data provided for the specified fuels and concentration range; precision not established outside these conditions.
• Interferences and limitations: spectral overlaps and matrix interferences (notably from lead and certain elements/halides) that restrict applicability.
• Reporting: recommended units (mg/kg), minimum reporting information and how to present results and uncertainty.

Typical use and users

Primary users include accredited analytical laboratories, refinery and fuel quality control personnel, regulatory agencies enforcing fuel sulfur limits, instrument manufacturers (method implementation for EDXRF analysers) and R&D groups developing fuel‑testing protocols. The method is used where rapid, non‑destructive screening or routine sulfur monitoring in automotive fuels is required and where the sample matrix and expected sulfur range fall within the method’s validated scope.

Related standards

ISO 20847 is part of a family of ISO methods for sulfur determination in petroleum products; closely related documents include ISO 20846 (ultraviolet fluorescence method) and ISO 20884 (wavelength‑dispersive X‑ray fluorescence), which cover overlapping and complementary concentration ranges and instrumentation approaches. ISO 8754 is a more general EDXRF procedure for petroleum products and can be consulted for broader EDXRF practice.

FAQ

Q: What is this standard?

A: ISO 20847:2004 (St ISO 20847-2004 rus) is an International Standard that specifies an energy‑dispersive X‑ray fluorescence method for determining total sulfur in automotive gasoline and diesel fuels.

Q: What does it cover?

A: It covers EDXRF measurement procedures, calibration, sample handling and reporting for sulfur in motor gasolines (up to 2.7 % m/m oxygen) and diesel fuels (up to 5 % V/V FAME) within roughly 30 mg/kg to 500 mg/kg; it also describes known interferences and applicability limits.

Q: Who typically uses it?

A: Accredited test laboratories, refinery/fuel quality control teams, regulatory bodies enforcing sulfur specifications, instrument vendors implementing EDXRF methods, and researchers working on fuel analysis.

Q: Is it current or superseded?

A: The original ISO 20847:2004 publication remains the 2004 edition; the ISO catalogue notes the publication and subsequent systematic reviews/confirmations. Users should check the ISO catalogue or their national body for the most recent review status or any later revisions.

Q: Is it part of a series?

A: Yes — ISO 20847 is part of a group of ISO methods for sulfur in fuels, complementary to standards such as ISO 20846 (UV fluorescence), ISO 20884 (WDXRF) and ISO 8754 (general EDXRF practice). These related standards cover alternate techniques and different concentration ranges.
