JB/T 6647-2011Methods for chemical analysis of carbonates - Gas-volumetric method after combustion in a tube furnace for the determination of total carbon content (English PDF)

JB/T 6647-2011 is the English-translated version of 碳化物中总碳含量的测定 气体容量法.

JB/T 6647-2011 is a recommended Chinese machinery industry standard that describes a method of chemical analysis for carbides: the gas-volumetric determination of total carbon content after combustion in a tube furnace. It covers the method itself, the instruments, the standard reference materials and reagents, the analysis steps, the trial results and the test report. The determination runs over a mass fraction from 5.0 % to 21.0 %, and the standard applies to the determination of the total carbon content in carbides. It quotes GB/T 223.69. It replaces JB/T 6647-1993, was issued by the Ministry of Industry and Information Technology, and carries the Chinese classification H72 and ICS 77.160.
