Scope
This document specifies the method for determining the lubricant content in lubricant-containing metal powders. This method is also suitable for preparing samples to determine the elemental content, such as graphite and oxygen, the determination of which may be interfered with by the presence of lubricants.
The conditions for applying this method are: the suitable solvent for extracting lubricants is known and easily available.
