Metallic materials – Drop weight tear test for steels
This Standard specifies the method for conducting a drop weight tear test (DWTT) for carbon steel, low alloy steel, and similar materials. In particular, it applies to testing line-pipe, and strip or plate intended for line-pipe of 150 mm in diameter or greater but excludes the testing of weld metal. Where thickness is greater than 19 mm, an alternative method is permitted.
