An experimental methodology for determining the product of the external friction coefficient and the lateral pressure coefficient depending on the compacting pressure is proposed. The results of powder materials testing show that the values of the product of the external friction coefficient and the lateral pressure coefficient have strong correlation with the compacting pressure in the pressure range of 30-350 MPa. The hypothesis about the external friction coefficient and the lateral pressure coefficient product constancy (when the compacting pressure changes) has not been experimentally confirmed; however, it can be implemented for some powder materials in a limited compacting pressure range.
