This Part is part 9 of GB/T 7702. This Part replaces GB/T 7702.9-1997 Standard test method for ignition temperature of granular activated carbon from coal. This Part modifies and adopts U.S. ASTM D 3466.2006 Standard Test Method for Ignition Temperature of Granular Activated Carbon. Following changes have been made in this Part. a) Change the temperature measuring point into 2 temperature measuring points; b) Change the accuracy into that the difference between two parallel results shall not be more than 20°C. Compared with GB/T 7702.9-1997, the main changes of this Part are as follows. a) Add the test condition; and specify the air source for test use; b) Stipulate that the carbon layer shall be covered with the quartz beads with the thickness of 15 mm and diameter of 3 mm, in order to prevent fluidization of the carbon layer; c) Revise the schematic diagram of quartz ignition tube; and specify the specification and size of the quartz ignition tube. d) Added Chapter 3 “Terms and definitions”.
