This Technical Report describes the principal drum tests used to asses the physical strength of coke. These tests involve rotation of the coke in drums of different dimensions for different durations, and lead to the production of different indices. Additionally the available experimental evidence relating the various strength indices has been consulted. Such evidence relates the principal as well as secondary indices. In this Technical report, all available statistical relationships between the principal strength indices have been listed and where possible illustrated graphically.
