This standard specifies the dimensions of an unnotched impact test piece of sintered metal materials (excluding hardmetals). The test piece may be obtained directly by pressing and sintering or by machining a sintered part.
This standard applies to unnotched impact test piece for sintered metal materials (excluding hardmetals).
2 Field of application
This standard applies to all sintered metal and alloys, with the exception of hardmetals. However, for certain sintered materials with low porosity or 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 GB/T 229-2007).
Note: For sintered metal porous materials, the results obtained from impact tests are not necessarily very accurate and should not be compared with results obtained from tests on solid metals.
