Application Summary AI generated

This standard specifies a modified Soxhlet extraction method for determining the lubricant content in lubricated metal-powder mixes. It is applied in the powder metallurgy industry to ensure consistent lubricant levels in powders used for compacting and sintering processes. The method is critical for quality control during the production of metal components, such as automotive parts and bearings, where precise lubricant content affects pressing behavior and final part properties.
