ISO 10070 is an international standard on metallic powders that discusses the criteria for measuring the air permeability of metal powders. ISO 10070 specifies a method of measuring the air permeability and the porosity of a packed bed of metal powder, and of deriving therefrom the value of the envelope-specific surface area. The permeability is determined under steady-state flow conditions, using a laminar flow of air at a pressure near atmospheric.
Several different methods have been proposed for this determination, and several test devices are available commercially. They give similar, reproducible results, provided that the general instructions given in ISO 10070 are respected, and the test parameters are identical. BS EN ISO 10070:2019 history
