1 Scope This standard specifies the method for determining the particle size distribution of granular activated carbon. The minimum amount of the tested granular activated carbon retained on the 180 μm standard sieve is specified as 90%. This standard is applicable to wooden granular activated carbon. 2 Method summary Place the mass-known activated carbon on the top sieve of a group of test sieves, vibrate it for a certain time under standard conditions, and then determine the percentage of activated carbon retained on each sieve and bottom tray in the total amount. 3 Apparatus
