10ppm Diesel is a middle distillate and is primarily used as a fuel in the road transport sector. Diesel engines do not use high-voltage spark ignition, instead fuel ignition takes place as a result of compression of the inlet air mixture and then injection of fuel. Diesel can be blended with biofuels such as FAME content of up to 7 vol.% (B7).

- May contain an ignition improver in which case carbon residue test is not valid and the cetane number minimum will apply.
- The limiting value for carbon residue is based on product prior to addition of ignition improver, if used. If a value exceeding the limit is obtained on a finished fuel, alkyl nitrate presence should be calculated in accordance with BS EN ISO 13759. If an ignition improver is present, the limit value for carbon residue of the product shall not be applied. Use of additives does not exempt fuels from conforming to the maximum 0.30% (m/m) carbon residue prior to addition.
- Calculation of the cetane index will also require distillation values at 10%, 50% and 90% (V/V) recovery points.
- Sulphur measurements include HMRC approved marker.
- Oxidation stability by BS 2000-388 is a requirement for all fuels. BS EN 15751 is an additional requirement for fuels containing FAME at concentrations at/or exceeding 2.0% (V/V).
- FAME meets the requirements of BS EN 14214.
