This Part is part 14 of GB/T 7702.

This Part replaces GB/T 7702.14-1997 Standard test method for sulphur capacity of granular activated carbon from coal and GB/T 7702.22-1997 Standard test method for granular activated carbon from coal - Determination of breakthrough sulphur capacity.

Compared with GB/T 7702.14-1997 and GB/T 7702.22-1997, the main changes of this Part are as follows.

a) Change the standard structural according to GB/T 1.1-2000 Directives for standardization - Part 1: Rules for the structure and drafting of standards and GB/T 20001.4-2001 Rules for drafting standards - Part 4: Methods of chemical analysis;

b) Combine the GB/T 7702.14-1997 Standard test method for sulphur capacity of granular activated carbon from coal and GB/T 7702.22-1997 Standard test method for granular activated carbon from coal - Determination of breakthrough sulphur capacity into GB/T 7702.14-2008 Test method for granular activated carbon from coal - Determination of sulphur capacity;

c) Stipulate that the division value of timer is 0.1s;

d) Correct the volume fraction of oxygen of saturated sulphur capacity to be 0.6% ~ 1.0%;

e) Modify the metrological quantity and units according to regulations.
