Petroleum products and related materials - Determination of hydrocarbon types - Fluorescent indicator adsorption method
This document specifies a fluorescent indicator adsorption method for the determination of hydrocarbon types over the concentration ranges from 5 % (V/V) to 99 % (V/V) aromatic hydrocarbons, 0,3 % (V/V) to 55 % (V/V) olefins, and 1 % (V/V) to 95 % (V/V) saturated hydrocarbons in petroleum fractions that distil below 315 °C. This method can apply to concentrations outside these ranges, but the precision has not been determined.
When samples containing oxygenated blending components are analysed, the hydrocarbon type results can be reported on an oxygenate-free basis or, when the oxygenate content is known, the results can be corrected to a total-sample basis.
This test method is applicable to full boiling range products. Cooperative data have established that the precision statement does not apply to petroleum fractions with narrow boiling ranges near the 315 °C limit. Such samples are not eluted properly, and results are erratic.
It does not apply to samples containing dark-coloured components that interfere with reading the chromatographic bands that cannot be analysed.
NOTE 1 The oxygenated blending components methanol, ethanol, tert-butyl methyl ether (MTBE), methyl tert-pentyl ether (TAME) and tert-butyl ethyl ether (ETBE) do not interfere with the determination of hydrocarbon types at concentrations normally found in commercial petroleum blends. These oxygenated compounds are not detected since they elute with the alcohol desorbent. The effects of other oxygenated compounds are individually verified.
NOTE 2 For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction and the volume fraction.

Overview
EN 15553:2021/prA1 (CEN) specifies the fluorescent indicator adsorption (FIA) method for the determination of hydrocarbon types in petroleum products and related materials. The method separates and quantifies aromatics, olefins and saturated hydrocarbons in petroleum fractions that distil below 315 °C. This amendment (prA1) updates precision data and clarifies reproducibility for certain concentration levels.
Key topics and requirements
- Scope and concentration ranges
- Aromatics: 5 % (V/V) to 99 % (V/V)
- Olefins: 0.3 % (V/V) to 55 % (V/V)
- Saturates: 1 % (V/V) to 95 % (V/V)
- Method may be applied outside these ranges, but precision has not been established there.
- Applicability
- For petroleum fractions distilling below 315 °C and full boiling range products.
- Not suitable for samples with dark-coloured components that prevent reading chromatographic bands.
- Samples with narrow boiling ranges near 315 °C can elute improperly; precision statement does not apply.
- Oxygenated blending components
- Common oxygenates (methanol, ethanol, MTBE, TAME, ETBE) do not interfere at commercial concentrations because they elute with the alcohol desorbent and are not detected by this method.
- Results may be reported on an oxygenate-free basis or corrected to a total-sample basis when oxygenate content is known.
- Precision and reproducibility
- The document provides repeatability (r) and reproducibility (R) figures across concentration levels for aromatics, olefins and saturates. The prA1 amendment updates select entries (for example, aromatics level corrected to 95 % and saturates reproducibility adjusted to 4.0 % (V/V)).
- Safety
- The method involves hazardous materials and equipment; users must establish appropriate health, safety and regulatory practices.
Applications
- Quality control and composition profiling of gasoline, diesel and other petroleum fractions.
- Regulatory compliance, blending verification and formulation control where hydrocarbon class composition (aromatic, olefinic, saturated) is required.
- Feedstock and product specification in refineries, fuel laboratories and petrochemical quality laboratories.
Who should use this standard
- Laboratory managers and chemists in refining, fuel testing, petrochemical and regulatory labs.
- Technical personnel responsible for fuel blending, specifications and compliance.
- Standards bodies and auditors evaluating analytical methods for hydrocarbon class determination.
Related standards
- Refer to other CEN or ISO methods for complementary analyses (e.g., boiling range, distillation, oxygenate quantification). Always consult national implementations and safety regulations when applying EN 15553:2021/prA1.
