[MW:15710] interpretation of the sub size,impact value and the temprature reduction as per asme 31.3 (table 323.3.4)

Dear experts
I have a dout in the interpretation of the sub
size,impact value and the temprature reduction as per asme 31.3 table
323.3.4) and the material code (asme sec 12A for sa350 LF2,333GR6
table 5 and table 6 )
question is :- If the test piece is 3 inch sch 40 (thicknes 5.49)
and the thickness of the machined specimen for the impact is 5 mm
(more than the 80% thickness of the test specimen).do we have to
perform the impact test on the specimen what will be the test
temprature -46 deg centigrade or -57 deg centigrade.
and what will be the impact value required for single and average.
