ASTM C 421-88 Standard Test Method for Tumbling Friability of Preformed Block-Type Thermal Insulation, 2 pp (Comm C-lQ... [Pg.405]

A drop shatter test has also been described for determining the friability of coal (ASTM, 2011e) which is similar to the standard method used as a shatter test for coke (ASTM, 2011m). In this method, a 50 lb sample of coal (2-3 in. [4.5-7.6 cm]) is dropped twice from a drop-bottom box onto a steel plate 6 ft below the box. The materials shattered by the two drops are then screened over round-hole screens with 3.0 in. (76.2 mm), 2.0 in. (50.8 mm), 1.5 in. (38.1 mm), 1.0 in. (25.4 nun), 0.75 in. (19.05 mm), and 0.5 in. (12.7 mm) openings and the average particle size is determined. [Pg.264]
