Section I, PW-41.2.2 "In welding single-welded butt joints, complete penetration at the root is required. This shall be demonstrated by the qualification of the procedure to be used", How to carry out? Use a butt weld coupon with single side?
base metal design is not a essential variable in Sec IX!

You have to ensure that the procedure you are using gets the full penetration. It is required to make a mock-up.
