Activity refers to all sites of an organization, under the same quality assurance management and using the same quality assurance plan, performing work to which this document is applicable. 3-1.4 APPLICABLE FABRICATION DOCUMENT. Applicable fabrication document is the document invoked by the contract, purchase order, or circular of requirements governing the work being accomplished. 3-1.5 APPROVAL (APPROVED). Approval means the item under consideration requires acceptance by NAVSEA or its authorized representative. “Approval” or “approved”, as used herein, is granted by the NAVSEA -authorized representative unless NAVSEA approval is specified. 3-1.6 AUTHORIZED REPRESENTATIVE.

A first article test is the fabrication and evaluation of a production part or simulated configuration of a production part using an automatic robotic welding procedure to validate weld bead placement and soundness. In this context, “part” can encompass weldments such as structural panels or foundati ons and sub-assemblies (piping or structural). 3-1.9 INSIDE DIAMETER (ID). ID refers to the inner surface or inside of a weld joint, usually in piping; ID can also mean an inside diameter of nominal dimension in a cylindrical, hollow product if the context is such.
