I am using a third party service for performing NDE on my ASME jobs. This third party has established procedures and is carrying out NDE in varuious ASME shops. As per T150(a) A procedure demonstration shall be performed to the satisfaction of the INspector this applies for all NDE (rt,ut,mt,pt).

MY QUERY IS IF I AM HIRING A THIRD PARTY WHO HAS ALREADY ESTABLISHED AND DEMONSTRATED THEIR PROCEDURES, DO I NEED TO DEMONSTRATE THE SAME IN MY WORKSHOP?
IF YES WHERE CAN I FIND SPECIFIC REQUIREMENT SAYING EACH WORKSHOP HAS TO DEMONSTRATE THE PROCEDURE, EVENTHOUGH IT HAS BEEN DEMONSTRATED AT SOME OTHER WORKS. As to me T150(a) and Appendix 12 in Sec V are not saying about the third party services.

I have read this question before.
The Manufacturer shall ensure the procedure works and shall certify to have demonstrated the procedure to the AI. If you are the Manufacturer, accomplish it.
