BS EN 590:2009 specifies requirements and test methods for marketed and delivered automotive diesel fuel. It is applicable to automotive diesel fuel for use in diesel engine vehicles designed to run on automotive diesel fuel.

BS EN 590 provodes guidance for:

• Pump marking
• Requirements and test methods

  - Dyes and markers

  - Additives

  - Fatty acid methyl ester (FAME)

  - Generally applicable requirements and related test methods

  - Climate dependent requirements and related test methods

  - Precision and dispute.

BS EN 590:2009 supersedes BS EN 590:2004, which is withdrawn.

Significant technical changes between this standards and the previous edition are:

• Provision is made for a maximum of 7 % (V/V) of fatty acid methyl esters (FAME) to be included in automotive diesel fuel
• Inclusion of the revised EN 14214 FAME specification
• Clarification of the fact that cold flow requirements of FAME when used as an extender for diesel according to this specification do not apply
• Addition of the Ignition Quality Tester as an alternate test method to the CFR engine test
• Deletion of the 350 mg/kg sulfur content
• Inclusion of the revised total contamination test method EN 12662
• Inclusion of the revised EN 12916, which is now able to distinguish between polycyclic aromatic hydrocarbons and FAME
• Inclusion of an additional requirement and method to determine the oxidation stability
• Addition of a workmanship clause and a note referring to good house keeping
• A general update of the revised test methods, some of them already having been included in the Technical Corrigendum to the previous version.
