A test portion is heated in a non-oxidizing atmosphere at a fixed temperature and the loss of mass is determined. The apparent oil content is calculated in terms of loss of mass. To ensure a non-oxidizing atmosphere, some drops of toluene are added to the crucibles.
Abstract
Overview
ISO 6997:1985 specifies a conventional gravimetric to determine the of calcined coke used in aluminium production. The test measures mass loss after heating a weighed sample in a ; the result is reported as percentage loss by mass. The method is intended as an indicator of oil-related mass loss (not the true chemical oil content) and provides two procedures: a and a .
