Liquid petroleum products - Fatty acid methyl esters (FAME) for use in diesel engines and heating applications - Requirements and test methods
1Key Takeaways
This European Standard specifies requirements and test methods for the marketing and delivery of fatty acid methyl esters (hereinafter referred to as FAME) for use in diesel engines and heating applications, in 100% concentration in fuels or as extenders in distillate fuels for diesel engines and heating applications c…
2Expert Interpretation
This in-depth analysis of the BS EN 14214:2019+A2 standard for fatty acid methyl esters (FAME) as a fuel for diesel engines and heating applications covers physical and chemical specifications, climate adaptability, additive specifications, and dispute resolution mechanisms. Key parameters such as a 96.5% minimum ester content and 8-hour oxidation stability are covered, along with a cold filter plugging point classification scheme for blended fuels.
Analysis of the core content of the standard
Fatty acid methyl ester (FAME) is a renewable fuel, and its technical specifications are unified throughout the EU through this European standard.
- Oxidation stability increased from 6 hours to 8 hours (at 110°C)
- The upper limit of monoglyceride content is reduced from 0.8% to 0.7%
- New technical clauses for heating fuel application scenarios
Key performance indicator comparison
| Test items | Unit | Limit range | Test method |
|---|---|---|---|
| Ester content | %(m/m) | ≥96.5 | EN 14103 |
| Kinematic viscosity at 40℃ | mm²/s | 3.50-5.00 | EN ISO 3104 |
| Oxidation stability | hours | ≥8 | EN 14112 |
Climate adaptability requirements
The standard innovatively distinguishes between the different climatic requirements of pure FAME fuel and mixed components:
Pure FAME fuel grades
| Grades | Cold filter plugging point (CFPP) |
|---|---|
| Summer Grade | ≤+5℃ |
| Arctic Grade | ≤-26℃ |
Mixed Component Grading
Ensure low temperature operability through combined control of monoglyceride content (0.15%-0.7%) and cold filter plugging point
Implementation Recommendations
- Additive Use: It is recommended to add antioxidants (such as BHT) before storage, but attention should be paid to the risk of low temperature precipitation
- Dispute Resolution: Density disputes shall be based on EN ISO 12185 (15℃), and oxidation stability disputes shall be based on EN 15751
- Sampling Specifications: Strictly follow EN ISO 3170/3171, with special attention to the sample container requirements for monoglyceride determination
