scope:

This standard specifies the dimensions of an unnotched impact test piece of sintered metal materials. The test piece may be obtained directly by pressing and sintering or by machining a sintered part. This standard applies to all sintered metals and alloys, with the exception of hardmetals. However, for certain materials (for example, materials having low porosity or materials with high ductility), it may be more appropriate to use a notched test piece which, in this case, will give results with less scatter (In this case refer to ISO 83 or ISO 148).
