The national requirements shall be set out in detail or shall be referred to by reference in a national annex to this European Standard. In view of the sensitivity of some of the test methods referred to in this European Standard, particular attention shall be paid to compliance with any guidance on sampling containers, which is sometimes included in the test method standard. It is essential that for sampling of Ethanol (E85) automotive fuel the containers used to take and store the samples before testing are free from any contamination. 4 Pump marking Information to be marked on dispensing pumps used for delivering Ethanol (E85) automotive fuel, and the dimensions of the mark shall be in accordance with the requirements of national standards or regulations for the marking of pumps for Ethanol (E85) automotive fuel. Such requirements shall be set out in detail or shall be referred to by reference in a national annex to this European Standard. NOTE The recommended designation for Ethanol (E85) automotive fuel and its seasonal derivatives is "E85". SIST EN 15293:2011

5.1 Dyes and markers The use of dyes and markers is allowed provided they do not cause harmful side effects to vehicles and fuel distribution systems. 5.2 Additives In order to improve the performance quality the use of additives is allowed. Suitable fuel additives without known harmful side effects are recommended in the appropriate amount, to help to avoid deterioration of driveability and emissions control durability. Other technical means with equivalent effect may also be used. CAUTION — Ethanol (E85) automotive fuel shall be free from any adulterant or contaminant that may render the fuel unacceptable for use in petrol engine vehicles designed to run on unleaded petrol and ethanol (E85) automotive fuel. NOTE Test methods for deposit forming tendency that are suitable for routine control purposes have not yet been identified and developed. 5.3 Phosphorus In order to protect automotive catalyst systems, phosphorus containing additives shall not be used in Ethanol (E85) automotive fuel. 5.4 Denaturants The presence of petrol that conforms to EN 228 is generally considered sufficient to render Ethanol (E85) automotive fuel a denatured product. If the presence of petrol is not recognized as a denaturant of ethanol by the relevant national authority, to avoid material compatibility issues with automotive engines and fuel systems, it is recommended to select denaturants from the list below that are known to be non harmful to vehicle systems:  Ethyltertbutylether (ETBE);  Methyltertbutylether (MTBE);  Tertiary Butyl Alcohol (TBA);  2-methyl-1-propanol (isobutanol); an
