BS 6043-1.4:1981
This standard BS 6043-1.4:1981 Methods of sampling and test for carbonaceous materials used in aluminium manufacture. Electrode pitch is classified in these ICS categories:
- 71.100.10 Materials for aluminium production
- 75.140 Waxes, bituminous materials and other petroleum products
This International Standard specifies a gravimetric method for the determination of the content of toluene-insoluble material in pitch used for the production of aluminium.
NOTE The content of toluene-insoluble material is commonly called “sum of resins α + β”.
