In determining compliancewith the standards set forth in this subarticle 2, an applicable sampling methodology set forth in 13 C.C.R. section 2296 shall be used. (b) Test Methods.(1) In determining compliance with the gasoline standards set forth in this subarticle 2, including those in thesections identified in Table 1, the test methods presented in Table 1 shall be used. All identified test methods are incorporated herein by reference. Table 1

Low Level Sulfur Calibration Procedure Reagents Thiophene, at least 99% purity2-Methylthiophene, at least 98% purity Toluene, reagent grade 2,2,4-Trimethylpentane, reagent grade Preparation of Stock Standard Weigh standard materials thiophene (° 0.7290 gm) and 2-methylthiophene (° 0.7031 gm) separately into a tared volumetric flask and record the individual mass to 0.1 mg. Add "mixed solvent" containing 25% toluene and 75% iso-octane(by volume) into the flask to a net weight of approximately 50 gm and record the weight. This "Stock Standard" contains approximately 10 mg/gm sulfur. The actual sulfer concentration can be calculated as follows: Sulfur from thiophene (gm) = Weight of thiophene *32.06* purity/84.14 Sulfur from 2-methylthiophene (gm) = Weight of 2-methylthiophene *32.06* purity/98.17 Sulfur concentration of Stock Standard (gm/gm) = (sulfur from thiophene + sulfur from 2-methylthiophene)/net weight of the stock standard Multiply the sulfur concentration by 1000 to convert the unit to mg/gm. Preparation of Calibration Standards Pipet 2.5 ml of the Stock Standard to 250 ml flask and dilute with the "mixed solvent" to the mark. The "Diluted Standard" contains approximately 100 mg/kg sulfur. Prepare 5, 10, 20, 30, 50, 75 ppm calibration standards by pipetting 5, 10, 20, 30, 50, 75 ml of the Diluted Standard into a 100 ml flask, respectively, and diluting with the "mixed solvent" to the mark. The actual concentration of the calibration standard should be determined from thestock standard. The standards with concentration ranging from 5 to 100 ppm and the "mixed solvent" are to be used for calibrating the instrument. d Replace ASTM D 2622-94 reproducibility values with the following:

Sulfur Content, ppm Reproducibility 10 to 30 40.5% x Sulfur Content (ppm) >30 19.2% x Sulfur Content (ppm)

e The reproducibility of benzene is as follows: Reproducibility = 0.1409 (X 1.133 ), where X = vol % f Add the following reproducibility statement for oxygenate-containing samples:

Range Reproducibility Olefins 0.3 - 33 0.819(X) 0.6 X = Volume %

g Replace ASTM D6550-00 reproducibility equation with the following: Reproducibility = 0.32 X0.5 where X is between 0.3 and 25 mass % olefin h The conversion from mass % olefin to volume % olefin is defined as follows: volume % olefin = 0.857 * 13 CA ADC § 2263 Page 2 13 CCR § 2263 Cal.

i Replace the last sentence in ASTM D6550-00 section 1.1 with the following: The application range is from 0.3 to 25 mass % total olefins. j The reproducibility of total aromatic hydrocarbon is as follows: Reproducibility = 1.4 volume% (c) Equivalent Test Methods. Whenever this section provides for the use of a specified test method, another test method may be used following a determination by the executive officer that the other method producesresults equivalent to the results with the specified method. <General Materials (GM) - References, Annotations, or Tables> Note: Authority cited: Sections 39600, 39601 , 43013 , 43013.1 , 43018 and 43101, Health and Safety Code ; and Western Oil and Gas Ass'n. v.
