The maximumconcentration limit for each grade of gasoline is specified inTable 1.6.2.1.1 If mutually agreed upon by the fuel producer andadditive vendor, tetraethyl lead antiknock mixture may bediluted with 20 mass percent of a mixed aromatic sol

29、venthaving a minimum flash point of 60 C according to TestMethods D93 when the product is to be handled in coldclimates. The TEL content of the dilute product is reduced to49 mass percent, so that the amount of antiknock additive mustbe adjusted to achieve the necessary lead level. The diluteproduct
