Scope
This document specifies the method for determining the bulk density of powder mixtures at high temperatures, which is mainly applicable to hot-pressed steel powders. The method is primarily based on the bulk density determination method (funnel method) specified in ISO 39231. The two funnels can be selected after consultation between the relevant parties.
