Th

25、e balance shall contain noadded ingredients other than kerosine, an approved oxidationinhibitor, and blue dye, as specified herein. 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 lea

26、d antiknock mixture may bediluted with 20 mass % of a mixed aromatic solvent having aminimum flash point of 60C according to Test Methods D93when the product is to be handled in cold climates. The TELcontent of the dilute product is reduced to 49 mass %, so thatthe amount of antiknock additive must

27、be adjusted to achievethe necessary lead level. The dilute product still delivers twobromine atoms per atom of lead.6.2.2 DyesThe maximum concentration limits in eachgrade of gasoline are specified in Table 1.6.2.2.1 The only blue dye that shall be present in thefinished gasoline shall be essentiall
