NF EN ISO 5754, A95-326 (10/2023)

This document specifies the dimensions of an unnotched impact test specimen, made of sintered metallic materials. The specimen can either be obtained directly by compression and sintering, or taken by machining from a sintered part. This document applies to all sintered metals and alloys, excluding hardmetals. However, for certain materials (for example, materials with low porosity, or high ductility), it may be more appropriate to use a notched specimen which then reduces the dispersion of the results (in this case, see ISO 148-1). NOTE For porous sintered materials, the results obtained during impact tests on unnotched specimens in accordance with this standard are not entirely comparable to those obtained during tests carried out on compact metals, on notched specimens.
