Lubricated metal-powder mixes - Determination of lubricant content - Soxhlet extraction method (ISO 13944:2012)
ISO 13944:2012 specifies a method for the determination of the lubricant content of a powder mix. The method is also suitable for preparing samples for measuring the content of elements, e.g. graphite and oxygen, the determination of which is interfered with by the presence of a lubricant.
A condition of the application of the method is that a suitable solvent for the lubricant concerned is known and available.
