Sec. 03.03.05.04. Specifications for No. 1 and No. 2 Fuel Oil (ASTM D-396)

No. 1 fuel oil is a distillate oil intended for vaporizing pot-type and similar burners. No. 2 fuel oil is a distillate oil for general purpose domestic heating use in burners not requiring No. 1 fuel oil. Both shall meet the requirements of the following specifications, when tested in accordance with the latest version of the American Society for Testing and Materials Methods of Tests:

	No. 1 Fuel Oil	No. 2 Fuel Oil
A. Flash Point (ASTM D-93).	38°C (100°F) minimum	38°C (100°F) minimum
B. Pour Point (ASTM D-97).	-18°C (0°F) maximum	-7°C (20°F) maximum
C. Visible Water and Sediment (ASTM D-1796) percent by volume maximum.	0.05	0.05
D. Viscosity (ASTM D-445).
(1) Kinematic at 40°C, centistokes.
(a) Minimum	1.3	1.9*
(b) Maximum	2.1	3.4
(2) Kinematic at 100°F, centistokes.
(a) Minimum	1.4	2.0*
(b) Maximum	2.2	3.6
E. Gravity (ASTM D-287). API minimum.	35°	30°
F. Distillation (ASTM D-86).
(1) 10 percent point maximum	216°C (420°F)
(2) 90 percent point maximum	288°C (550°F)	338°C (640°F)
G. Sulfur (ASTM D-1552) percent by mass shall not exceed the following maximums:
(1) On and after July 1, 2016	0.05	0.05
(2) On and after July 1, 2019	0.0015	0.0015
(3) No. 1 and No. 2 Fuel Oil that was stored in this State by the ultimate final consumer prior to July 1, 2019, which met the applicable maximum allowable sulfur content for fuel oil before July 1, 2019, set forth in §G(1) of this regulation at the time it was stored, may be used by the ultimate consumer in the State on and after July 1, 2019, until the supply is depleted.

H. Color. No. 1 and No. 2 fuel oil, containing greater than 0.05 percent by mass sulfur, shall be dyed with Solvent Red 164 at the concentration spectrally equivalent to at least 3.9 pounds of the solid dye Standard Red 26 per 1,000 barrels in accordance with the mandates of the US EPA and IRS.

I. Cetane. Unless sold specifically and documented on all transfer documents as a burner fuel only, off-highway No. 2 fuel oil shall meet the same cetane requirements as stated in Regulation .02G of this chapter.

* Lower or higher pour points may be specified whenever required by conditions of storage or use. When pour point less than -18°C (0°F) is specified, the minimum viscosity shall be 1.7 centistokes.
