[MW:20440] AWS D1.1 PQR QUALIFICATION USING 1" PIPE


 1)      Does D1.1 restrict usage of 1" pipe for PQR qualification?
2)      Does D1.1 restrict usage of full section tensile specimen?

Clause 4.9.3.4 tells about the reduced section tensile specimen only &
 Fig 4.14, they giving the specimen size details for 2",3",6" & 8" & above only. Does it mean we are not allowed to choose 1" for PQR qualification?
I've checked in D1.1 interpretations also I cannot able to find. If anyone have the details please share.
