ActivePermeable sintered metal materials—Determination of the air permeability
可渗透性烧结金属材料 透气度的测定
Application Summary AI generated
This standard specifies the method for determining the air permeability of permeable sintered metal materials, which are porous structures used for filtration, fluid distribution, or sound attenuation. It is applied in industries such as chemical processing, automotive, and aerospace for testing the flow characteristics of sintered metal filters, silencers, and fluidizing media. The standard ensures consistent measurement of how easily air passes through these materials under specified pressure conditions.
