(a) Charpy V-notch impact tests. Where required, Charpy V-notch tests shall be conducted in accordance with ASTM Specification E 23 (incorporated by reference, see § 54.01-1), Notched Bar Impact Testing of Metallic Materials, using the Type A specimen shown in Figure 4 of the specification.Special attention is drawn to the fact that the Charpy Keyhole and U-notch specimens

From the comparion, we find that though ASTM A131 AH36 steel and so called ASTM A131 AH36 steel equivalent materials have much in common. But they are not totally the same. Some even have different impact test requirements. As we know the ASTM A131 AH36 steel is shipbuilding steel, the ship needs to understand waves and corrossion of sea water.
ASTM A131 Grade D Steel Plate ,ASTM A131 GR.D, ASME SA ASTM A131 GR.D Shipbuilding Steel Plates, machining parts is fabricated by the general strength steel material. ASME SA131 Grade D Plate is widely used for building decks of ships, vessels and boats, other normal repairing works in shipyards.ASTM A131 Grade D SBQ Plates are supplied under the ASTM/ASME specification (ASTM A131 / ASME SA 131) which is the standard specification for
ASTM E23 Charpy Impact Testing Sub-Size Specimens; - ASTM E23 and ISO 148-1 define test methods for Charpy impact testing of notched-bar metallic specimens. ASTM A370 also includes Charpy impact test method requirements but focuses only on steel products. All three standards provide details for properly measuring the energy absorbed by the notched specimen when impacted by a swinging pendulum.

Charpy V-Notch Toughness Of HSS Steel Tube InstituteThe average CVN impact values of the test specimens shall conform to the minimum requirement of 25 ft-lb at 40 °F, based on full-sized (10×10 mm with a 2 mm deep notch) test specimens. Such a CVN toughness level (at the test location) is adequate for dynamic loading application for the Zone 2 service temperature range (0 °F to -30 °F) as per the AASHTO bridge design specification (2007).
Do Pressure Vessel Design Codes Require Charpy Impact Test?"Supplemental Test PQR" is used to record other types of test results such as hardness, macro, etc. when they were not done on the original PQR. Here a screenshot of a PQR in ProWrite showing that Toughness Test becomes available when the Test Requirements field is set to "With Supplementary" and Charpy Impact Testing is being required.
The specimens of ASTM A333 Gr.6 should be cooled a sufficient time in the test container so that both reach the desired temperature. The temperature shall be measured by thermometers. The specimens shall be quickly transferred from the cooling device to the anvil of the Charpy impact testing machine and broken with a time lapse of not more than
