NF EN ISO 14556, A03-015 (05/2023)

This document specifies an instrumented Charpy V-notch impact test method for metal products and requirements for measuring and recording equipment. Compared to the impact bending test on Charpy specimen described in standard ISO 148-1, this test provides additional information on the breaking behavior of the product subjected to impact test conditions. The results of analyzes carried out using the instrumented Charpy test are not directly transferable to structures or components and should not be used directly in design calculations or in safety assessment. NOTE General information on the instrumented impact bending test method can be found in References [1] to [5].
