- Scope
- This standard specifies the method for the determination of the specific surface area of metal powders. This standard applies to the determination of the specific surface area of metal powders. The measuring range is 0.1m2/g～1000m2/g. The determination of the specific surface area of non-metallic powder and microporous materials can also be used as a reference. The specific surface area measured in this standard is the total specific surface area of the powder, including the specific surface area of any openings where nitrogen molecules can enter the powder body; it is different from the specific surface area measured by the air permeation method, which refers to the envelope surface area.
