Applications
→Used to determine and evaluate whether the V-shaped and U-shaped notches of metal impact specimens are qualified.
→The processed V-shaped and U-shaped metal impact specimens are enlarged onto the projector screen and compared with the standard sample diagrams of the V-shaped and U-shaped notches of metal impact specimens on the projector screen to determine whether the notch processing of the tested impact specimen is qualified.
→The CST-50 impact specimen notch projector is designed and manufactured in accordance with the "GB/T229 - Method for Impact Test of Metallic Materials by the Spherical Drop Impact Apparatus".
