Crush the laboratory sample to pass a 6.3 mm sieve. If the quantity exceeds 2.3 kg, divide the sample to obtain about 2.3 kg and crush this fraction to pass a 850 μm (No. 20) sieve. Further divide the sample to obtain a portion of approximately 200 g and crush to pass a 250 μm (No. 60) sieve. Divide again to obtain approximately 50 g. This is the analysis sample which is dried to constant weight at 110 °C ± 5 °C.; ash; petroleum coke;
