§ 2263. Sampling Procedures and Test Methods.

(a) Sampling Procedures. In determining compliance

with 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 the

sections 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

____________

a

Do not report values below the limit of detection

(LOD) specified in the test method. Where a test method does not specify a LOD, do not report values below

the lower limit of the scope of the test method.

b

Delete paragraph 4(b) concerning sampling.

c Make the following modifications to paragraph 9.1:

Low Level Sulfur Calibration Procedure

Reagents Thiophene, at least 99% purity

2-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 the

stock 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 *

mass % olefin

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 produces

results equivalent to the results with the specified method.
