The color
24、identifies the difference for engines that have a low tolerance to lead.NOTE 2Listing of, and requirements for, Avgas Grades 91/98, 108/135108/135, and 115/145 appeared in the 1967 version of this specification. U.S.Military Specification MIL-G-5572F, dated January 24, 1978 (withdrawn March 22, 1988
25、), also covers grade 115/145 aviation gasoline, and is availableas a research report.4 Listing of, and requirements for, Avgas Grade 80 appeared in the 2016 version of this specification.5.3 Although the grade designations show only a single octane rating for each grade, they shall meet a minimum le

Materials and Manufacture6.1 Aviation gasoline, except as otherwise specified in this specification, shall consist of blends of refined hydrocarbons derivedfrom crude petroleum, natural gasoline, or blends, thereof,
27、 with synthetic hydrocarbons or aromatic hydrocarbons, or both.4 Supporting data have been filed at ASTM International Headquarters and may be obtained by requesting Research Report RR:D02-1255.D910 1726.2 AdditivesMandatory, shall be added to each grade of aviation gasoline in the amount and of the
28、 composition specified inthe following list of approved materials.6.2.1 Tetraethyl Lead, shall be added in the form of an antiknock mixture containing not less than 61 mass percent of tetraethyllead and sufficient ethylene dibromide to provide two bromine atoms per atom of lead. The balance shall co

The TEL content of the dilute product is reduced to 49 mass percent, so that the amountof antiknock additive must
31、be adjusted to achieve the necessary lead level. The dilute product still delivers two bromine atoms peratom of lead.6.2.2 DyesThe maximum concentration limits in each grade of gasoline are specified in Table 1.6.2.2.1 The only blue dye that shall be present in the finished gasoline shall be essenti
