ASTM D1857/D1857M-18 PDF Download

"Standard Test Method for Fusibility of Coal and Coke Ash" is the name of the ASTM D1857/D1857M-18 standard. Through observation of the temperatures at which triangular pyramids (cones) made from the ash achieve specific, defined stages of fusing and flow, this test method is used to assess the fusibility of coal and coke ash.

The fusibility temperatures of ash are crucial for predicting whether the ash will remain solid or become fluid during the process, which is why they are taken into account when designing coal combustion and coal conversion equipment. For maintaining optimal performance and minimizing problems like slagging, this information is essential.

The standard highlights the empirical nature of the test procedure and the importance of adhering strictly to the criteria and specifications laid out in order to produce reproducible findings. This guarantees that measurements from various laboratories will be accurate and consistent.
