#ECOR2506859SReference Test Methods for ED95 Fuel
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
This decision sets the official reference test methods for ED95 fuel and for the hydrated ethanol blended into it. It lists the standards laboratories must use to measure properties such as density, ethanol content, water content, lubricity, acidity, sulfur, phosphates, chlorides, and contamination. Fuel producers, importers, distributors, testing laboratories, and compliance teams should use these listed methods, or equivalent EU/EEA methods that meet the same accuracy and reliability conditions. The decision is mainly a technical compliance update, not a broad policy change.

Key Changes
- Sets reference test methods for key ED95 fuel properties, including density, ethanol content, water content, MTBE, isobutanol, and lubricity.
- Sets reference test methods for hydrated ethanol used in ED95, covering alcohol content, acidity, flash point, water, sulfur, phosphates, chlorides, copper, and other quality measures.
- Allows equivalent EU or EEA test methods if they meet the required standards for accuracy, reliability, traceability, and reproducibility.
Obligations
What this law requires
Use NF EN ISO 12185:2024 as the reference test method to measure ED95 fuel density at 15 °C, unless using an equivalent EU or EEA method meeting the required precision, reliability, traceability, and reproducibility conditions.
Use NF EN ISO 22854:2025 as the reference test method to measure ethanol content in ED95 fuel, unless using an equivalent EU or EEA method meeting the required precision, reliability, traceability, and reproducibility conditions.
When applying the ED95 ethanol-content test method, dehydrate the product before injection and ensure the water percentage is below 0.05% by mass.
Use NF EN 15692:2021 as the reference test method to measure water content in ED95 fuel, unless using an equivalent EU or EEA method meeting the required precision, reliability, traceability, and reproducibility conditions.
When applying the ED95 water-content test method, adjust the test sample volume to 1 to 2 ml instead of the 4 to 8 ml specified in the cited standard.
