EN 15470:2017
(Main)Liquefied petroleum gases - Determination of dissolved residues - High temperature Gas chromatographic method
General Information
- Abstract
This European Standard specifies a method for determining the dissolved residual matter in liquefied petroleum gases (LPG), in the range of 40 mg/kg to 100 mg/kg. Higher concentrations can be determined by adjusting the sample size.
The dissolved residue is the amount of organic compounds that are detectable by gas chromatography after evaporation of the sample at ambient temperature and then in an oven at 105 °C.
This method is not suitable for detecting solid materials or for possibly high molar mass polymers (>1 000 g/mol).
From the analysis of a limited LPG sample size (50 g to 75 g) this method allows obtaining information on the potential origin of the residue (gasoil, lubricants, plasticizers, etc.).
The precision data of the method have been determined from 20 mg/kg to 100 mg/kg. For a higher content of residue, the precision has not been tested.
NOTE An alternative European Standard, EN 1547113[1], specifies a gravimetric method.
WARNING - The use of this Standard can involve hazardous materials, operations and equipment. This Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of users of this standard to take appropriate measures to ensure the safety and health of personnel prior to application of the standard, and fulfil statutory and regulatory requirements for this purpose.

Overview
EN 15470:2017 - Liquefied petroleum gases (LPG) - specifies a high temperature gas chromatographic method for the determination of dissolved residues in LPG. The method quantifies organic residues detectable by gas chromatography after controlled evaporation (ambient then oven at 105 °C) and is validated for the range 40 mg/kg to 100 mg/kg (precision data determined from 20 mg/kg to 100 mg/kg). Higher residue concentrations can be measured by adjusting sample size. The method is not suitable for solids or very high molar mass polymers (>1 000 g/mol).
Key topics and technical requirements
- Sample size and sampling: typical LPG test sample 50 g to 75 g; sampling in accordance with EN ISO 4257.
- Evaporation procedure: controlled evaporation at ambient temperature followed by heating in an oven at 105 °C for 1 hour to remove volatile LPG and concentrate dissolved residues.
- Extraction and internal standard: residue is dissolved in solvent (carbon disulfide, CS2) and quantified using an internal standard (normal octane / n‑C8).
- Gas chromatography: capillary GC with high‑temperature column (suggested HT5 type programmable to 400 °C) and FID detection; integration covers peaks from n‑C8 to end of run.
- Quantification and calculation: internal standard method used to calculate evaporation residue (ER) expressed in mg/kg; blank checks and baseline stability required.
- Precision: repeatability and reproducibility established from inter-laboratory studies for residues between 20–100 mg/kg.
- Safety: work in explosion‑proof hood, control of static electricity, safe handling of volatile and hazardous reagents (CS2), adherence to statutory safety regulations.
Practical applications and users
- Quality control laboratories testing LPG batches for contamination or compliance.
- LPG producers and distributors monitoring dissolved residues that may indicate contamination with gasoil, lubricants, plasticizers or other sources.
- Regulatory bodies and certification labs performing standardized checks for fuel specifications.
- Automotive and appliance fuel testing where trace organic residues can affect performance or safety.
- Forensic or failure‑analysis teams seeking to identify potential origin of residues from small sample sizes.
Benefits: provides a repeatable, GC‑based analytical route for identifying and quantifying organic contamination in LPG and offers diagnostic insight into residue origin (e.g., lubricants or fuel oils).
