AASHTO T243
Full Name
AASHTO T243 – Standard Method of Test for Sampling Procedure for Impact Testing of Structural Steel
Scope
This specification establishes the procedure for Charpy V-notch testing of structural steel and contains two frequencies of testing.
The impact properties of steel can vary within the same heat and piece, be it as-rolled, control-rolled, or heat treated. The purchaser should therefore be aware that testing of one plate, bar, or shape does not provide assurance that all plates, bars, or shapes of the same heat as processed will be identical in toughness with the product tested. Normalizing or quenching and tempering the product will reduce the degree of variation.
