Enforcement Advisory: #152: Table of Motor Vehicle Fuel Specifications
|Advisory Number 152|
January 30, 1998
GASOLINE AND DIESEL FUEL SPECIFICATIONS, LEGAL AND
EQUIVALENT TEST METHODS, AND REPRODUCIBILITIES
Sections 2250 through 2282 of Title 13 of the California Code of Regulations (CCR) specify California Air Resources Board (CARB) motor vehicle fuel standards and test methods used in measuring the physical and chemical properties of gasoline and diesel fuel. The table on the back of this advisory summarizes these properties, standards, and test methods. Test methods deemed equivalent by the Air Resources Board are also shown in the table. Please note that the test methods which are underlined are the methods currently used by the Compliance Division of CARB.
Note that there are no test methods for deposit control additives listed in the table. Section 2257 contains performance criteria that deposit control additive/gasoline formulations must meet to be certified by the Air Resources Board. Once a formulation is certified, testing for the particular additive is performed using the test method specified by that additive's manufacturer. These methods vary for each additive, and are not listed in the table.
For your information, the table only lists CARB standards and test methods. Standards and test methods used by other state and federal agencies are not listed. The standards enforced by the California Department of Food and Agriculture's Division of Measurement Standards (DMS) are contained in CCR Title 4, Section 4140 (gasoline) and Section 4143 (diesel).
