Modification of procedure Appendix Al of Method allows detection of 5 ppm sulfur.

Technical Manual for the Analysis of Fuels

This approach is practical since the number of possible components in any gaseous fuel is relatively limited, while the range of concentration varies widely according to the source of the gas, Gaseous fuel standards are available from commercial suppliers in “certi- fied” and d115 grades. As with RDSF, the chief weakness of the meth- ods that are not intended for peat analyses d1145 be inadequate sample size.

The combined volume of water and sediment is measured volu- metrically at the d114 of a centrifuge tube after a The bulb is then cool- ed in a dessicator and weigh- ed. Second, caution should be used in the comparison of any precision informa- tion s1145 in Table VII-3 that derives from tests on coal and coke. The appa- ratus is immersed in a constant temperature bath at Coal Due to the oxidation of coal, it is important that analyses be conducted as soon as possible after sample collection.


Sample should be collected at the source. Additional information on the methods of analysis is tabulated in Section 3″of this chapter.

Should be applicable to MF. Applicable to petroleum fuel oils, gasolines, lu- bricating oils, and certain other petroleum products. A compact apparent density may also be determined by applying a 9. See Refer- ence ill for details. Generally applicable to crude petroleum and petro- leum products normally handled as liquids and having a Reid vapor pres- sure of 1.

Measurement of the calorific value and density of isolated i. Additional information on the methods of analysis, including alternate methods for most parameters is given in Section 3 of this chapter.

Salt water qstm in the tanks is the source of the chlorides. Additional informa- tion is given in Reference 3. For mesh pulps see D in Reference fl. Nitrogen compounds are likely to be present as amines in methyl fuel. For ast, in dissolution of coal, pro- cesses might involve hydrogenation, catalysis, thermal liquefaction, and a host of other variables, singly or in combination.

ASTM D – 80 Test Method for Sampling Natural Gas (Withdrawn )

Applicable to fuel oils, lube oils, and other petro- leum liquids. These are the sample requirements for a single analysis of coal qstm coke and may be significantly different from the amount of RDSF needed. Section 3 of this chapter provides additional information on analytical procedures, as well as alternate methods.


Coals are comprised of five major elements: To carry out this procedure, the follow- ing general steps1 should be followed: Should be appli- cable to RDSF.

Nitrogen in shale oil naphtha fraction is present as pyridines, pyrroles, and nitriles. Repeatability; Carbon – 0. The number given for repeatability is the acceptable difference for duplicate results by the same laboratory; that for reproducibility is the acceptable differ- ence for duplicate results submitted by two or more laboratories.

ASTM D2983 Lubricating Oils Lubricants Low-Temperature Brookfield Viscometer

Generally applicable to dry solid waste samples containing 0. For coal and coke: However, it should be stressed that the basis upon which an analysis is reported must be specified. Applicable to motor and aviation gasolines, avia- tion turbine fuels, dis- tilate fuel oils, and similar petroleum pro- ducts. The chlo- rine compounds liberated are absorbed in a sodium carbonate solution and the amount of chlorine present determined gravimetrlcally by precipita- tion as silver chloride.

A weighed sample is burned in a bomb calorimeter and the calorific value determined from temperature and time observations made before, during, and after combustion. But, again, the choice seems reasonable.
