GB/T 13390-2008 Metallic powder—Determination of the specific surface area—Method of nitrogen adsorption
Abstract
This standard specifies the method for determining the specific surface area of metal powders. This standard is applicable to the determination of the specific surface area of metal powders. The measurement range is 0.1 m2/g to 1,000 m2/g. The specific surface area of non-metallic powders and microporous materials can also be used for reference. The specific surface area determined by this standard is the total specific surface area of the powder, including the specific surface area of any openings that nitrogen molecules can enter into the powder body; it is different from the specific surface area determined by the air permeation method, which refers to the envelope surface area.
