NBN EN ISO 5755:2012

ISO 5755:2012 specifies the requirements for the chemical composition and the mechanical and physical properties of sintered metal materials used for bearings and structural parts.
When selecting powder metallurgical (PM) materials, it should be taken into account that the properties depend not only on the chemical composition and density, but also on the production methods. The properties of sintered materials giving satisfactory service in particular applications may not necessarily be the same as those of wrought or cast materials that might otherwise be used. Therefore, liaison with prospective suppliers is recommended.
