BS 6043-1.11:2000

This standard BS 6043-1.11:2000 Methods of sampling and test for carbonaceous materials used in aluminium manufacture is classified in these ICS categories:

• 71.100.10 Materials for aluminium production

This International Standard describes a method for the determination of the atomic carbon/hydrogen ratio of quinoline-insoluble material isolated from coal-tar pitches. A procedure for the isolation of the quinoline-insoluble material in a form suitable for the analysis is described.

NOTE The isolation procedure is not an alternative to ISO 6971¹⁾, which is to be used in all cases where the amount of quinoline-insoluble matter present in a pitch is to be determined.
