MIL-STD-2035 is the acceptance criteria for VT and other NDE methods. It is used when referenced by the fabrication document such as NAVSEA S9074-AR-GIB-010/278 or a different fabrication standard or the customer's drawings.
All military fabrication documents include a provision stating the hierarchy or precedence of the other documents. Generally, there is an upper tier document that addresses the general requirements of construction. That document references other working documents such different NAVSEA documents for qualifying the welding process, a fabrication document for actual fabrication requirements, a different working document for acceptance criteria, and a standard for qualifying inspection personnel. Also referenced are various material standards, painting standards, standards for properly marking items, cleaning standards, packing standards, etc. All of these requirements can be modified by the customer (Government agency. Such modifications, i.e., exceptions, additional requirements, material substitutions, etc. are usually noted in the project specifications or purchase order. Generally, the construction drawings are reviewed and approved by the customer. Exceptions taken by the contractor/fabricator are suppose to be noted during the submission process. All exception or modifications to the contract documents are supported by letters of approval. Those letters are noted on the approved drawings so that anyone reviewing the drawings at a latter time understands the modifications have been noted and approved by the client. The bottom line is the approved drawing and approved bill of materials becomes the "Bible" for the purposes of construction.
