Alabama Administrative Code › Title 80 - ALABAMA DEPARTMENT OF AGRICULTURE AND INDUSTRIES › AGRICULTURAL CHEMISTRY › Chapter 80-1-16 - STANDARDS FOR GASOLINE AND GASOHOL › Section 80-1-16-.03 - Minimum Standards For Gasoline

Current through Register Vol. 42, No. 9, June 28, 2024
Specifications for gasoline, unless noted, shall be
				  determined in accordance with the test methods presented in the latest edition
				  of The American Society For Testing and Materials Standards, hereinafter
				  designated as ASTM, and those specifications that are published by the United
				  States Department of Commerce as required by
Code of Ala.
				  1975
, §
									8-17-81.
				  Gasoline which is sold or used in Alabama must meet the following minimum
				  standards:
(See Exhibit for Rule at end of Chapter.)
(a) Sulfur - ASTM Method D-1266, D-3120 and
				D-2622. The sulfur content shall not exceed .10% by weight for unleaded
				gasoline and .15% for leaded gasoline.
(b) Corrosion - ASTM Method D-130, Copper
				strip corrosion shall not exceed No. 1 on the ASTM test scale after three hours
				at 122° F.
(c) Existent Gum -
				ASTM Method D-381. The existent gum shall not exceed 5 milligrams per 100
				milliliters.
(d) Lead - ASTM Method
				D-2599, D-3229, D-3237. The existence of lead shall not exceed 4.2 grams per
				gallon for leaded and .05 grams per gallon for unleaded.
(e) Phosphorous - ASTM Method D-3231. The
				existence of phosphorous in unleaded gasoline shall not exceed .005 grams per
				gallon.
(f) Volatility - ASTM
				Method D-86, D-323, D-2533 and D-4953. The volatility requirements for
				distillation, Reid Vapor Pressure and Vapor Liquid Ratio shall be as listed in
				Table 1 and Table 2, attached as exhibits to this rule, in accordance with the
				schedule for Alabama Volatility Requirements as follows:
(g) The octane rating (Antiknock Index) shall
				equal that specified in the product registration and that posted in accordance
				with FTC Octane Posting and Certification rule. The minimum (R+M/2) Octane
				rating of premium grades shall be 90 for unleaded gasoline and shall be 93 for
				leaded gasoline. The minimum (R+M/2) Octane rating of regular grades shall be
				87 for unleaded gasoline and shall be 89 for leaded gasoline. In addition, the
				motor octane number must not be less than 82.0 for unleaded gasolines with a
				minimum R+M/2 Octane rating of 87. The above octane requirements will not be
				applicable to intermediate grades when such product has a brand name or
				numerical designation that meets minimum Antiknock Index of regular grades and
				does not imply a higher Antiknock Index than it actually has and is not
				misleading to the consumer as to its quality.
(h) The sale of any gasoline under any trade
				name which shall indicate to the purchaser that it is of a certain grade is
				prohibited unless the Antiknock Index therein is at least equal to that
				required above for that certain grade.
(i) Water and sediment. The finished gasoline
				shall be visually free of undissolved water, sediment, and suspended matter and
				shall be clear and bright at the ambient temperature or 70°F (21°C),
				whichever is higher.

*Distillation Temperatures C (F) % Evaporated.
*Vapor Pressure KPA (PSI).
*Products containing 9 - 10% ethanol are exempt from the
				  midpoint (50%Vol) distillation requirements provided the base gasoline meets
				  the requirements as set forth.
*Blends of 9-10% ethanol and gasoline will be granted an
				  additional 1.0 PSI tolerance for vapor pressure, and the minimum test
				  temperature for Vapor Lock Protection for Class 2, 3 and 4 shall be: Class 2
				  (49°C) 120°F; Class 3(45°C) 113°F; and Class 4 (41.5° C)
				  107° F respectively at which the Vapor/Liquid Ration (V/L) equals
				  20.
