摘要

Standard test methods for routine coal analysis in the United States include those of the American Society for Testing and Materials (ASTM) and, with limited application, those of the International Organization of Standardization (ISO). The former consist of national standards used in the United States and Canada, while the latter have been developed by ISO member nations for international trade. While these methods are used throughout the coal industry and in commerce to establish coal quality, they may not be applicable in the analysis of coal samples for research purposes. One problem area is the chemical analysis of coal. This becomes particularly evident when using ASTM methods which were primarily designed for the analysis of bituminous coal to analyze lignetic and subbituminous coals. Here, researchers and analysts find themselves trying to fit a square peg in a round hole. In this paper some of the difficulties that have been observed in our analysis of research coal samples for major, minor, and trace elements are emphasized, and suggestions for eliminating these problems are presented. 11 refs.
