Specifies a gravimetric method, the principle of which consists in weighing the fraction of a test portion of pitch which is insoluble in toluene after boiling for a specified period.
Abstract
Overview
ISO 6376:1980 specifies a for determining the content of in electrode pitch used in the production of aluminium. The standard defines a practical laboratory procedure: dissolve a measured test portion of pitch in hot toluene, reflux for a specified time, collect and dry the insoluble fraction, and express the result as a percentage by mass. was developed by ISO/TC 47 (Chemistry) and is also approved by IUPAC.
