EN 15940 standard governs paraffinic fuel oils to ensure their quality. Read these specifications in detail here to learn about them.
Paraffinic diesel fuels are synthetically made, sustainable, and biodegradable, and they can be used as replacement fuels for BS 590 diesel. Its examples include HVO fuel (Hydrotreated Vegetable Oil) and Shell GTL. These are new-generation fuels that produce extremely low emissions and can serve as a drop-in replacement for ULSD in vehicles with OEM approval.
Below are the EN 15940 specifications that govern paraffinic diesel fuels.
