Scope

This part of ISO 148 specifies the pendulum impact test method on miniature Charpy-type V-notch test pieces of metallic materials. This part of ISO 148 does not cover instrumented impact testing of miniature Charpy V-notch test pieces, which is specified in Annex D of ISO 14556.This International Standard can be applied, by agreement, to other impact testing machines, such as drop-weight towers or high-speed servo-hydraulic machines.The user should be aware that data obtained from miniature test pieces might not be directly comparable to those obtained from full-size standard Charpy V-notch test pieces and that suitable correlation procedures have to be employed.[1,2]
