Coking coals possess the ability, when heated in the absence of air, to soften, swell and then re-solidify to form a coherent, porous, hard coke structure. The Gieseler Plastometer and Arnu Dilatometer tests are used to evaluate the rheological or plastic properties of a coal or coal .This guide includes brief descriptions of all 56 ASTM test methods that cover the physical, chemical, and spectroscopic analytical techniques to qualitatively and quantitatively identify . For these reasons, a prediction of coke quality (shatter index and ASTM hardness factor) using Australian coals was undertaken in terms of the microlithotypes, vitrite and clarite. .Tests on coke from pilot and commercial ovens have indicated that the amount of coke fines produced when crushing to 3/4-inch top size for the chemical industry is dependent on the .
The earliest standard tests were for the examination of cold coke strength properties, termed the Micum, and Irsid tests [9], as well as ASTM tests for stability and .
Two indexes of its strength, the stability factor and the hardness factor, are determined by sieve analysis of the coke after treatment. Studies have indicated that there is no real difference in .ASTM's physical and mechanical testing standards provide guides for the proper procedures employed in the determination of the physical, mechanical, and metallographic properties of certain materials, particularly metals and alloys. . parameters like elastic moduli, impact strength, ductility, hardness, residual stress, and grain size are . A number of measures have been developed globally as a proxy for coke behaviour within the blast furnace. The earliest standard tests were for the examination of cold coke strength properties, termed the Micum, and Irsid tests [9], as well as ASTM tests for stability and hardness (currently standard D3402 [10], previously D294 [11]).3. Summary of Test Method 3.1 A sample of dry coke of designated size is tumbled in a rotating drum at a specified turning rate for a specified number of revolutions. Two indexes of its strength, the stability factor and the hardness factor, are determined by sieve analysis of the coke after treatment.
coke behaviour within the blast furnace. The earliest standard tests were for the examination of cold coke strength properties, termed the Micum, and Irsid tests [9], as well as ASTM tests for stability and hardness (currently standard D3402 [10], previously D294 [11]). More recently adopted were the coke strength after reaction (CSR) and the .
test. Despite undergoing strict process monitoring of the testing procedure of hot strength of coke, the present study confirmed that a variation of ±2 points in coke CSR and CRI does not affect coke quality in a single reading. The study also includes the influence of the number of coke pieces in the test sample to optimize the coke bed .tumbler test data in table 7. Coke Screenings vs. ASTM Tumbler Stability Each coke produced in the pilot oven was sized and tested for strength by the ASTM tumbler procedure. The percentages of minus 1/8-inch screenings obtained from crushing tests were plotted against their respective tumbler stability indices,ASTM STABILITY AND HARDNESS, ISO MICUM/IRSID AND JIS JAPANESE TUMBLER TESTS These coke tumbler tests measure the resistance of coke to impact and abrasion during removal from the coke oven and transportation, and the abrasion that occurs during its descent in the blast furnace. The ASTM, ISO and JIS tumbler tests differ in the coke sample size

The ASTM, ISO and JIS tumbler tests differ in the coke sample sizeMoisture, volatile matter and ash are three of the primary parameters used for assessing the quality of coal. A new ASTM standard that covers the use of a macro thermogravimetric analyzer for the determination of moisture, volatile matter and ash in analysis samples of coal and coke has recently been approved by ASTM International Committee D05 on Coal and Coke.
