ASTM D 2. Not applicable for materials containing N-0, N-N linkages. Spiking should only be attempted if the fuel is very finely divided and is easily mixed in a ball or roller mill. The bulb is then cool- ed in a dessicator and weigh- ed. The time in seconds it takes a fixed volume of zstm to flow through a capillary is measured.

Estimated based on prices charged by analytical service laboratories in early Note that many values are in ml. For coal, sum of weights should be with- in 21 of initial sample weight. Not applicable if value is less than 0.

A polished copper strip in im- mersed in a sample at a certain temperature for a astmm charac- teristic of the sample being tested. Discussion of Results 5.

See Reference 06 for additional information. Compositional analysis of the heavier petroleum fractions e.

Technical Manual for the Analysis of Fuels

The parties concerned should agree on a sampling procedure for each pro- ject. No attempt was made – in the preparation of this manual – to review all available methods because of limitations on time and funds. Van Nostrand’s Scientific Encyclopedia. Quantities of the sample required, costs, and standard reference materials where available are given in Table III Bureau of Mines American Petroleum Institute 4.

Should be ade- quate for RDSF. Caution should be used in the comparison of any precision information given in Table V However, it should be stressed that the basis upon which an analysis is reported must be specified. Generally applicable to in- dustrial aromatic hydrocar- bons and related materials. The fuels covered in this manual are: Additional information on the methods of analysis, including alternate methods for some parameters, is given in Section 3 of this chap- ter.

Also the methods covered here for RDSF are not intended to be applicable to refuse-derived liq- uid fuels, industrial refuse-derived fuels, or agricultural and forestry wastes. Significant discrepancies can be seen in the results for peat and, to a much lesser extent, for the processed municipal refuse.

ASTM D – 80 Test Method for Sampling Natural Gas (Withdrawn )

Differences which may occur in sample size and pre- paration are described in Section 3, dealing with actual methods. After thorough mixing of the material, portions for the various analytical de- terminations are astj and placed in appropriate containers. An appropraite hydrometer is lowered astk the sample and allowed to settle.

Types of Reference Materials 97 3. Selection of butyl rubber is based on preliminary results of laboratory tests carried out by Arthur D.

A sample is digested in a mix- ture of sulfuric acid, potas- sium sulfate and mercuric ox- ide converting nitrogen to ammonium sulfate. Liquefied petroleum gas 2. Test temperature must be speci- fied by the parties concerned.

Varies with vapor pressure; is 0. Should be applicable to RDSF. The number of gross samples depends upon the size of the lot. Laboratory 3 was “off” in some data, did not carry out many of the required solid fuel analyses, and did not perform duplicate analyses. The availability of the publication containing the method and the extent to which the method is currently used in laboratories con- ducting fuel analyses.

ASTM D See Notes 1 and 2 Determined indirectly by sub- tracting from the percent- ages of hydrogen, carbon, sul- fur, nitrogen, moisture, and ash. BS Part 3 A. Additional information on the methods of analysis, including alternate methods for most parameters is given in Section 3 of this chapter. The combined volume of water and sediment is measured volu- metrically at the bottom of a centrifuge tube after a Refuse-Derived Solid Fuels 79 B.

Sulfur is present as mercaptans, sulfides, and thiophenes. HC1 is de- termined by titration. When more preci- sion is required in the gross sample, the methods described in ASTM D”Standard Methods for Collection of a Gross Sample of Coal”1, may be applicable with only slight modification; Section 8 and Appendices A-l and A-2 of this method are especially pertinent.

Strip LPG which can be pressurized. Detailed procedures for every situation are not available. The “spiked” samples, together with a por- tion of the original “unspiked” material, are submitted for analysis.

These are the sample requirements for a single analysis of coal or coke and may be significantly different from the amount of RDSF needed. When working with peat that is not sufficiently homogeneous, d1415 sample sizes for these analyses should be increased, if possible.

1d145 Solid Fuels Table VII-3 gives, for each parameter of interest, additional information on the method s of analysis deemed suitable. 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.
