Scope
This standard specifies the dispersion treatment rules for refractory metals and their compounds before particle size measurement.
This standard applies to the dispersion treatment of refractory metals and their compounds such as tungsten, molybdenum, rhenium, tantalum, and tungsten carbide. Other metal powders (or carbides, nitrides) can also refer to this standard for dispersion treatment.
