1. SCOPE

1.1 This standard prescribes requirements, methods of sampling and test methods for two octane grades of E20 fuel, an admixture of anhydrous ethanol meeting IS 15464 at 20 percent by volume and ethanol free Motor Gasoline meeting IS 2796 at 80 percent volume, under each of BS IV and BS VI categories suitable for use as a fuel in the automobile spark-ignition internal combustion engines of vehicles complying with BS IV and BS VI emission norms respectively.

1.2 This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this specification to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
