GSO ISO 148-3:2013 Metallic materials -- Charpy pendulum impact test -- Part 3: Preparation and characterization of Charpy V-notch test pieces for indirect verification of pendulum impact machines
Abstract ISO 148-3:2008 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. ISO 148-3:2008 specifies notched test pieces with nominal dimensions identical to those specified in ISO 148-1; however, the tolerances are more stringent.
