Site Assessment

Plans tailored to you

Fuel testing
Kingspan's Fuel Management Plans are tailored to suit your business, depending on the results of your Fuel Resilience Survey carried out by our Fuel Specialists. The survey includes; assessment of EN590 and ISO4406:1999 compliance, OFTEC tank inspections, environmental risk assessment and collection & testing of fuel samples. Should any tanks need to be replaced, our team can also decommission old tanks and install new ones. 

If you have not had an inspection recently it is likely that your tanks and tank management systems may not be compliant with current legislation.

What is EN590 and ISO 4406:1999?

EN590 is an EU standard that outlines the properties that all diesel fuels need to meet before they are sold in the EU. Since its inception EN590 has been adapted to lower the Sulphur content of diesel and now allows the blending of up to 7% of bio-diesel with conventional diesel. Whilst this has some environmental benefits, it could also have a long-term impact in the performance of your stored fuel. 

Bio-diesel is hydroscopic, meaning it naturally absorbs water. As a result, you should regularly test your fuel to ensure it does not exceed the 200mg of water per kg (0.02%) standard outlined by EN590. The standard states that if your fuel does contain more that 0.02% of water per kg that you should ensure this is removed using an extraction process such as fuel polishing. In addition to the hydroscopic properties that bio-diesel possesses, it also reduced the Sulphur content of the diesel you use. Whilst this is an excellent environmental benefit, reduced Sulphur is ideal for diesel bug growth, therefore further contaminating the fuel. This can also be monitored and maintained through the implementation of an Intergrated Fuel Management Solution. 

ISO 4406:1999 is commonly referred to as the cleanliness code and consists of a three number rating system referring to the contaminant levels of correlating particles, 18/16/13. The particles are measured when oil flows past a fine laser beam, which has been programmed to look for particles that are 4, 6 and 14 microns in size. The volume of these are then reported. 

How does this relate to the 18/16/13 principle?

18/16/13 refers to the range in which these particles must fall within in order to be considered 'clean'. The particle volumes are then cross-referenced with the ISO Standard Table to find out whether the oil can be considered clean, with lower numbers in the code indicating fewer particles in the oil;
  • 18 = between 1300 - 2500 particles larger than 4 microns
  • 16 = between 320 - 640 particles larger than 6 microns
  • 13 = between 40 - 80 particles greater than 14 microns
In order to ensure your oil meets these standards you will need to have it regularly tested and polished where necessary.
