Popis
BS 6043-1.2:1981
This standard BS 6043-1.2:1981 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 an azeotropic distillation method for the determination of the water content of pitch used in the production of aluminium.
The method is applicable to pitches having water contents in the range 0,1 to 2 % (m/m).
NOTE Water contents in excess of 2 % (m/m) may be determined by means of this method by using a larger receiver.
Specifies an azeotropic method for the determination of the water content of pitch used in the production of aluminium.
