Note 21
Automotive gasolines can vary widely in composition. Addition of considerable amounts of aromatic and/or oxygenated solvents are common. When these cargoes have to be transported the tank coating should be fully cured. 
Blending of automotive gasolines with above mentioned additives in the tank is not acceptable.

Limits for oxygenated solvents (in volume) as set out in European Directive 2003/17/EC Annex III Type: Petrol

  1. Test methods shall be those specified in EN 228:1999. Member States may adopt the analytical method specified in replacement EN 228:1999 standard if it can be shown to give at least the same accuracy and at least the same level of precision as the analytical method it replaces.
     
  2. The values quoted in the specification are "true values". In the establishment of their limit values the terms of ISO4259 "Petroleum products - Determination and application of precision data in relation to methods of test" have been applied and in fixing a minimum value, a minimum difference of 2R above zero has been taken into account (R = reproductibility). The results of individual measurements shall be interpreted on the basis of the criteria described in ISO 4259 (published in 1995).
     
  3. Other mono-alcohols and ethers with a final boiling point no higher than that stated in EN 228:1999.
      
  4. In accordance with Article 3(2), by no later than January 2005 unleaded petrol with a maximum sulphur content of 10 mg/kg must be marketed and be available on an appropriately balanced geographical basis within the territory of a Member State. By 1 January 2009 all unleaded petrol marketed in the territory of a Member State must have a maximum sulphur content of 10 mg/kg.
