Is the following a permissible test configuration (UG-100): Pressure is supplied through a special test fitting that attaches to a vessel fitting. The vessel fitting is welded or brazed to the vessel and is listed as part of the vessel on the U-1. The special test fitting seals to the vessel fitting with o-rings on the ID or OD of the vessel fitting. (The ID or OD is used depending on the size of the vessel fitting.) As a result the joint attaching the vessel fitting is subject to test pressure, but the very end of the fitting does not see test pressure.
