Re: [MW:34285] Impact test requirement for Unlisted material (ASTM A707 L5 CL3)

Impact toughness test does not only depend on service temperature only, It also depends on working fluid, for example if your pipeline is sour service then impact toughness test should be conducted fot PQR qualification.
