All diesel fuels as defined above under the provisions of Code of Ala. 1975, § 8-17-80(2) as Diesel Fuel No. 1 and Diesel Fuel No. 2, hereinafter designated as 1-D and 2-D respectively, shall conform to the following tests and specifications:

(a) Flash point, (Method ASTM D-93) shall be:
1. 100° F for 1-D.
(b) 125° F for 2-D.
(2) Cloud point (Method ASTM D-2500 and D-975) for 1-D and 2-D shall be as follows: The cloud point, or wax appearance point, for cold weather operation is specified at 6° C above the 10th percentile minimum ambient temperatures for the area in which the fuel will be used. For Alabama the 10th percentile minimum temperatures are: September 13° C, October 4° C, November -3° C, December -6° C, January -7° C, February -3° C, March -2° C.
(3) Water and sediment, (Method ASTM-1796) for 1-D and 2-D shall be 0.05% by volume, maximum.
(4) Carbon residue on 10% residuum, (Ramsbottom Method ASTM D-524), the maximum allowance shall be:
(a) 0.15% for 1-D.
(b) 0.35% for 2-D.
(5) Ash, (Method ASTM D-482), maximum percent allowed by weight shall be 0.01% for 1-D and 2-D.
(6) Distillation temperatures, 90% point shall be as follows:
(a) For 1-D (Method ASTM D-86), 550° F maximum.
(b) For 2-D (Method ASTM D-86), 540° F minimum and 675° F maximum.
(7) Viscosity shall conform to one of the two methods listed below:
(a) Kinematic viscosity, at 40° C (Method ASTM D-445) for 1-D, 1.3 minimum and 2.4 maximum cSt.
(b) Kinematic viscosity, at 100° F (Method ASTM D-445) for 2-D, 2.0 minimum and 5.8 maximum cSt.
(8) The percent of sulfur, by weight, (Method ASTM D-127, D-2622, D-3120 and D-1552) for 1-D and 2-D shall be 0.50% maximum.
(9) Copper strip corrosion (Method ASTM D-130) for 1-D and 2-D shall be No. 3 maximum.
(10) The cetane index for both 1-D and 2-D shall be 40 minimum, (calculated) (ASTM Method D-976).
