GB/T 26930.6-2014 "Carbonaceous materials used in the production of aluminium - Coal tar pitch - Part 6: Determination of ash content" specifies the method for determining the ash content of coal tar pitch used in the production of primary aluminium. The method employs a high-temperature incineration process, in which a specified mass of coal tar pitch sample is gradually heated to a specific high temperature in a muffle furnace under defined conditions and incinerated to constant weight. The percentage of the residue's mass relative to the original sample's mass represents the ash content.
