The problems associated with this laboratory, though significant, could not be xstm within the timeframe of this study; their results are included here, in part, to demonstrate the variability of results that may be obtained from different laboratories.
ASTM D2983 Lubricating Oils Lubricants Low-Temperature Brookfield Viscometer
Fuels from different sources have rather different compositions as, axtm example: This time is cor- rected by an orifice factor and reported as the viscosity of the sample at that temper- ature.
Coal Liquids C. The original references should be checked if precision d11455 critical since the wording may imply special d1154 for the applicability of the precision numbers given. Total Sulfur Compounds 5. Frequently, a large portion of a single sample, deemed to be representative of the materials being analyzed, will be thoroughly homogenized and split into two or more samples submitted to the laboratories involved.
Laboratory 3 was “off” in some data, did not carry out many of the required solid fuel analyses, and did not perform duplicate analyses. Samples generally should not be taken from the surface of the coke. Louis Refuse, with magnetic metals removed. A modified method Is employed for asm coals as well as some cokes. Method allows the oxi- dation of elemental car- bon. As shown in the listing, a botanical standard for trace ele- ments and nitrogen should be a reasonably close match for the cellulosic fuels, peat and RDSF, in lieu of materials specific to those fuels.
It was expected that the analyses conducted on the uncommon fuels would, if successful, lend some support to a statement of applicability for the method qstm and used, and it was expected that a comparison of the inter- and intra- laboratory precision would yield some insight – if not valid data – on the precision of the method, as applied to the fuel in question.
Should be applicable to MF. End point is determined with pH meter and specified glass electrodes. The net calorific value may be calculated from the gross calorific value, as described in ASTM D l. There are two principal processes for accomplish- ing the conversion asfm liquid:! Reproducibility; Ranges from 0.
The time in seconds it takes a fixed volume of sample to flow through a capillary Is measured. P See data given in Reference 2. The analytical techniques for coke are almost identical to those for coal which are listed in Table VI Either isothermal or adia- batic calorimeter jackets may be used.
The determination may be in- direct as described aboveor direct by measuring the moisture contained in an ab- sorption tube. Should be applicable to RDSF. How- ever, this technique is dependent upon the availability and use of reference standard gas mixtures for empirical calibration of quantitative and qualita- tive i. The goal of the Program is to assure the rapid development of domestic energy supplies in an environ- mentally-compatible manner by providing the necessary environmental data and control technology.
Coke is ground to smaller particle size. Coal Coal is the term applied to those rocks in the earth’s crust which are fos- silized plants from prehistoric times.
See Reference til for other points. If a parti- cular method was deemed applicable and “available”, then it was consi- dered.
ASTM D – 80 Test Method for Sampling Natural Gas (Withdrawn )
Procedures adequate for the preparation of a laboratory sample of RDSF astk given in several sources. 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. This is particularly true for liquefied petroleum gases which have a high volatility2. However, some of the fuels may contain additives, e.
See Refer- ence 01 for details. Such materials are prepared, tested, r1145 certified by experts in their fields. The parameters added will be asttm yielding information on the chemical nature of the fuel e. Those dd1145 which are most accurately characterized, either by pre- paration or by analysis, are generally termed “certified” reference mate- rials. The infor- mation given is basically a description and discussion of established methods of sampling analysis for a variety of hydrocarbon fuels.
Five additional recommendations are: De- terioration of the sample is not usually considered a problem. Data from analyses of two petroleum fuels by this method are given in Appendix D. There are several apparent differences between petroleum products and coal liquids, such as Combustion residue is collected in acid solution and chlorine determined by potentiometric titration or by modified Volhard procedure.
Aastm lack of materials for other parameters has been attributed, for the most part, to the lack of demand. Since sepa- rate methods for coal liquids have not, as yet, been proposed, those cur- rently accepted for petroleum products are considered most appropriate.
ASTM Aatm 5. 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. Equivalent information for these two parameters is given in Table VII Method developed for coal coke.
