GB/T 26930.10-2014

This standard specifies an instrumental method for determining the sulfur content in coal tar pitch used as a binder in carbon electrodes for primary aluminium smelting. It is applied in quality control laboratories and production facilities to ensure the pitch meets specifications for anode and cathode manufacturing, where sulfur levels affect electrode performance and environmental emissions. The method provides a precise, automated alternative to traditional chemical analysis for raw material acceptance and process monitoring.
