The capillary is calibrated and used with a re- producible driving head and with a closely controlled tem- perature. These results wstm indicate the importance of sealed sample containers where moisture determinations are required, and the importance of thorough drying for samples containing significant amounts of water e. The accuracy of these measurements is, for the most part, a func- tion of the s1145 with which the calibration standards have been made.

Those likely to be required include trace elements in the fuel and in the ash, characterization of organic compounds present, and possi- bly, fuel-stability tests. Those likely to be required include: Speci- fically applicable to oxy- dd1145 compounds e. Coal Coal is the term applied to those rocks in the earth’s crust which are fos- silized plants from prehistoric times. Private communication with Mr.

Sample should be collected at the source.

Technical Manual for the Analysis of Fuels

Most of the methods described are already widely accepted for the analysis of petroleum fuels1. Either isothermal or adiabatic calorimeter jackets may be used.

For low ash coke, a large sample size of 5 g may be necessary. Liquid Fuels A listing of reference’ materials available for liquid fuels is given in Table A Gas turbine fuels 4.

The sample collection methods are based on those given in Dso the differences are minimal. Carbon Total and Hydrogen 2. After mixing thoroughly, portions for the various analytical procedures are weighed. Coal Due d11145 the oxidation of coal, it is important that analyses be conducted as soon as possible after sample collection. The coverage of non-standard methods and of additional parameters that may be required in environmental assessments will be included in a forth- x1145 Level 2 sampling and analysis manual.

The air dried sample is then crushed to pass a No. The water content may be measured, by weight difference, by this method, but may not be as accurate as the method specified in this manual – ASTM D This manual indicates what fuel analyses are normally required in connection with fuel-utilization research, and what established methods are applicable for the analysis. While no exact correlation exists between the Conradson D and Ramsbottom D methods for carbon residue, an appro- ximate correlation for petroleum products has been found and is shown graphically in Reference 1.

Not applicable to LPG.

All nitrogen re- duced to N2 and, after removal of COz, is measured volumetri- cally. Should be applicable for SO and CL. After mer- cury is precipitated with so- dium sulflde, the solution is made alkaline with sodium hy- droxide and the liberated am- monia distilled-into an asfm solution.

API units – Test temperature must be speci- fied by sstm parties concerned. Liquid Fuels 98 C. End point is determined aatm pH meter and specified glass electrodes.

P Varies with the initial boil- ing point and end point of the material and with the rate of change of thermometer readings. As can be seen, only a limited number of parameters are cover- ed by available materials.

For coal, sum of weights should be with- in 21 of initial sample weight. Coals are comprised of d1154 major elements: May be applicable to MF if sulfur is primar- ily connected with volatile compounds.

The predetermined temperature for the initial crude distillation is specified by the parties concerned in the evaluation; it is not specified in the method. Frequently, the composition is described in terms of solubility in various solvents, such as hexane, pentane, pyridine, and benzene.

Tests showed standard deviations for duplicate samples to be in the following ranges:
