Apparent Density NA Although the range of values for parameters will differ, the analytical procedures are essentially the same. Carbon Total and Awtm 2. However, it should be stressed that the basis upon which an analysis is reported must be specified.

Solid Fuels A listing of the reference materials available for solid fuels is given in Table A For petroleum oils with O.

Io- dine and bromine, if pre- sent, will add to chlorine result. Addi- tional information on the methods of analysis, including alternate methods for most parameters, is given in Section 3 of this chapter.

ASTM D2983 Lubricating Oils Lubricants Low-Temperature Brookfield Viscometer

The kinematic vis- cosity is the product of the measured flow time and the calibration constant of the viscometer. Modifications are pre- scribed for high residue mate- rials. Basically, it describes and discusses standard methods of sampling and analysis for a variety of hydrocarbon fuels. The coverage of non-standard methods and of additional parameters that may be required in environmental assessments will be included in a forth- coming Level 2 sampling and analysis manual.


Sample is burned in oxygen and calorific value is determined from temperature readings and other heat sources. Modification of procedure Appendix Al of Method allows detection of 5 ppm sulfur. BaCla is used to precipitate the sulfur. It is designed specifically d145 use with aviation turbine fuels when the permissible difference between duplicate determinations: Either isothermal or adia- batic calorimeter jackets may be used.

The correlation may not be valid for unusual petroleum products and, thus- SO and CLand ASTM urges caution in the application of this correlation at low carbon residues. Standard sampling methods for d11145 oil and coal liquids have not been developed, but the procedures given in ASTM D”Standard Method of Sampling Petroleum and Petroleum Products”1, will give a significant amount of guidance.

The methanol content may be derived s1145 the specific gravity, viscosity, boiling point, or vapor pressure, if the content of higher alcohols is small. Performance astj for gasoline, diesel oil, and gas turbine fuels strictly limit the amounts of these im- purities which may be present.

Section 3 of this chapter provides additional in- formation on analytical procedures, as well as alternate methods. Waste Lubricating Oil E. Assumes other halogens are not present; lower limit of applicability is 0. Test tem- perature should be specified by parties d11445.

There are two principal processes for accomplish- ing the conversion to liquid:! Refuse-Derived Solid Fuels Table VII-3 gives, for each parameter of interest, additional information on the method s of analysis deemed suitable. Because of this expecta- tion, and because the ASTM methods for coal and coke seem to be generally applicable to RDSF, they have been listed as the preferred method for all methods covered in their manual.


As with RDSF, the chief weakness of the meth- ods that are not intended for peat analyses may be inadequate sample size. Environmental assessments of processes using RDSF will need to include additional fuel analyses beyond those covered in this manual.

Refuse-Derived Solid Fuels 79 B. Specific references to methods listed are given in Table V Calorific Value ASTM D Sample is burned in closed system and sulfur oxides d114 absorbed as sulfate into sodium carbonate solution. See Reference 1 for additional information.

The increase in weight of the absorbent is measured, and the carbon dioxide content of the sample determined from this figure.

Specific references to methods listed are given in Table VI The peat asym specified the contents to be “pure” Canadian Ast Peat Moss.

Tetanus inoculation is one addi- tional precaution that could be taken. Description of Fuels A. With regard to the other methods, no data were available indicating the preferred methods were applicable.

Such is the case, for example, with the calorific value. The loss of weight of the sample is also determined.

Carbon Residue continued Si 00 Environmental Protection Technology 3. In addition, the final upgrading or refining of the coal liquid, e. But, again, the choice seems reasonable.
