Scope
This standard specifies the method for determining the specific surface area and particle size of metal powders and their compound powders - the air permeation method. This standard is applicable to the determination of the specific surface area and particle size of metal powders and their compound powders. This standard is not applicable to the determination of fibrous and flaky powders, but if both the supplier and the buyer agree upon it, this standard can also be used. This standard is not applicable to the determination of the specific surface area and particle size of mixed powders of different materials and powders containing binders or lubricants.
