Application Summary AI generated

This standard specifies the azeotropic distillation (Dean and Stark) method for determining the water content in coal tar pitch used as a binder for carbon electrodes in primary aluminium production. It is applied in quality control and material testing within the aluminium smelting industry to ensure pitch meets processing requirements for anode or cathode manufacturing. The method is critical for evaluating moisture levels that can affect electrode performance and energy efficiency during electrolysis.
