Metallic materials - Charpy pendulum impact test - Part 3: Preparation and characterization of Charpy V-notch test pieces for indirect verification of pendulum impact machines (ISO 148-3:2008); English version of DIN EN ISO 148-3:2009-06
This part of ISO 148 covers the requirements, preparation and methods for qualifying test pieces used for the
indirect verification of pendulum impact testing machines in accordance with ISO 148-2.
It specifies notched test pieces with nominal dimensions identical to those specified in ISO 148-1; however,
the tolerances are more stringent.
NOTE 1 The chemical composition or heat treatment or both are varied according to the energy level desired.
NOTE 2 Reference test pieces are qualified on reference pendulum impact testing machines which are also described
in this part of ISO 148.
