__________

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, ppmReproducibility
10 to 3040.5% X Sulfur Content (ppm)
>3019.2% X Sulfur Content (ppm)

e The reproducibility of benzene is as follows:

Reproducibility=0.1409 (x1.133), where X=vol %

f Add the following reproducibility statement for oxygenate-containing samples:

RangeReproducibility
Olefins0.3 - 330.819(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%

k Replace ASTM D6550-10 reproducibility equation with the following:

Reproducibility=0.32 X0.5

where X is between 0.3 and 25 mass % olefin

l The conversion from mass % olefin to volume % olefin is defined as follows:

volume % olefin=0.857 * mass % olefin

m Replace the last sentence in ASTM D6550-10 section 1.1 with the following:

The application range is from 0.3 to 25 mass % total olefins.

(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.
