Audit Nonconformance for Design of Choke Manifold

J

I have couple of issue with my previous API16C certificate getting regarding.
In my choke manifold design 3 1/8"-5K sizes 2-positive chokes and 3-gate valves and 2-spools and studded tees.
I did hydro static teste choke manifold on 7500psi.
------------------------------------------------------------------------------------
All things acceptable by auditor only testing pressure. So here he gave N.C.
So,my question is in API 6A 20th ed. shows testing presser is 7500psi for 5000psi equipment. And in API 16C shows 10000psi for 5000psi for choke manifold.
So, how can we apply 7500psi tested valves in 10000psi choke manifold. :confused:

Please anyone one who have great experience in API16C products who can help finish to solve my query.;)

Testing 10000psi choke manifold according to API 16C affirmative. But how can we use as per API 6A design choke valve tested on 7500PSI use? Isn't it bit wrong?
More over i found latest draft copy addendum API 16C for testing please check and justify to understand.
Please find the attachment.

After Assembly - test the completed manifold to 10,000 PSI

You can't would need a 10000psi valve in a 10000psi choke
