Statistical correlation of ASTM and JIS coke tumbler test results / W.R. Leeder and K. A. Jonasson. : M38-13/77-47E-PDF

"The objective of this report is to provide a means of relating results of the principal North American and Japanese standard tests of blast furnace coke quality, i.e., coke tumbler test factors or indices. Such relationships are needed to better understand the many advances being made by the Japanese as a world leader in coke-making research. For example, recent Japanese publications of importance to North American cokemakers, coal producers and researchers have related coal petrographic reflectance and thermal rheological properties to Japanese, but not to North American coke quality parameters. The relationship between the coke tumbler test indices is necessary to interpret the quality of Canadian coking coal resources as seen from either the North American or Japanese points of view, and as such is important to the CANMET program for Canadian self-sufficiency for coking coals"--Introd., p. [1].
