Query on UW-11(a)(4) 1

[juancito]

It regards with UW-11(a)(4) that deals with the exemption of Rx for the circunferencial butwelds between flanges and nozzle necks when: "neither exeed NPS10 nor 1.125in wall thickness". Because of lenguage, this sentence is somehow tricky for our understanding. Does it mean that a NPS12 nozzle with 0.25in wall thickness is exempt of Rx because is thinner than 1.125 or because is larger than 10NPS it has to be Rx? Again, if a NPS 8 nozzle is 1.5in thick, is it exempted from RX because the diameter? (of course the vessel is 100% Rx, and not lethal)
I would kindly appreciate your help on this matter, and also if you can address me a reference to support your comment. My supplier and I do not agree on this point and need strong arguments to end up this discussion.
Thanks in advance
Juan

Our English language. The key word is "neither" if you do not wish to x-ray. The part may not exceed NPS 10". The part must not exceed 1.125" in thickness. There is no credit
for the combination.
