What is a Charpy Impact Test? - TWI

The standard Charpy-V notch specimen is 55mm long,10mm square and has a 2mm deep notch with a tip radius of 0.25mm machined on one face.In some circumstances,sub-size Charpy specimens can be tested with thickness less than 10mm.The specimen is supported at its two ends on an anvil and struck on the opposite face to the notch by the pendulum.Validity of Charpy tests on thick material - Metal and Oct 05,2004 anchored tanks Minimum Charpy V notch Requirements for Plate Specimens#0183;Charpy V-notch impact testing is basically a method for evaluating ductile to brittle transition temperature fracture behavior of metals,and as such does not directly take into account the affects of material thickness.Indirectly,it is a qualitative approach forSome results are removed in response to a notice of local law requirement.For more information,please see here.12345Next[DOC]APPENDIX QLOW-PRESSURE STORAGE TANKS FOR anchored tanks Minimum Charpy V notch Requirements for Plate Specimens#0183;Web viewCharpy V-notch specimens that conform to ASTM E 23 shall be taken from the weld metal and from the heat-affected zone of the welding procedure qualification test plates or duplicate test plates.R.4.1.2 Weld metal impact specimens shall be taken across the weld with the notch in the weld metal.
