This document specifies the pendulum impact test method on miniature Charpy-type V-notch test pieces of metallic materials. This document does not cover instrumented impact testing of miniature Charpy-type V-notch test pieces, which is specified in ISO 14556:2023, Annex D[1]. This document 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 are not directly comparable to those obtained from full-size standard Charpy V-notch test pieces[2],[3].
