DESCRIPTION

BS ISO 5940-1:2019


This standard BS ISO 5940-1:2019 Carbonaceous materials for the production of aluminium. Pitch for electrodes is classified in these ICS categories:
  • 71.100.10 Materials for aluminium production

This document specifies the ring-and-ball method, a method of using the ring-and-ball apparatus for the determination of the softening point (softening temperature) of pitch used in the production of aluminium.

The method is applicable to pitches having softening points equal to or greater than 30 °C.
