5.2.2 “Format of the 3D TDP based models

shall be as directed by the contract

or purchase order”

Excerpts from MIL-STD-31000A Feb 2013



Audit for Long Term Archiving and Retrieval

Excerpts from EN/NAS 9300-110 draft 2014-10-07

5.2 “…The objective is to demonstrate that the process still preserves the

essential information for the 3D shape of the product, as defined by the

original CAD system the moment the CAD system was released.”
