Downloaded from https://www.everyspec.com MIL-STD-31000A APPENDIX A associated lists (DI-SESS-81000E or DI-CMAN-80776A) should be selected when there is a current or future need for the Government to procure or manufacture the equipment, components, or spares and repair parts from either the original manufacturer or an alternate source. Product drawings/models should be ordered only under contracts containing engineering and manufacturing development or production tasks and are part of a Production Level TDP.
When product drawings/models are ordered for large, complex items such as major weapons systems, tailoring decisions should include consideration of ordering commercial drawings/models for selected commercial items used as subassemblies. It should also be noted that where there are fully justified DoD peculiar drawing practices requirements, such as the DoD system for Numbering, Coding and Identification, ASME Y14.100 and applicable appendices should be invoked . The use of the appendices to ASME Y14.100 will usually be associated with product drawings indicating a DoD activity as design activity and an end item requiring Government logistics support.
A.2.4.4 Commercial drawings/models and associated lists. Commercial drawings/models and associated lists (DI-SESS-81003E) are used to obtain existing information regarding commercial items acquired by the Government and used as end items or as selected subassemblies of Government developed items. They are not to be used for documenting vendor items in a production level TDP. Furthermore, the acquisition of technical data should conform to the requirements of DFARS 252.227-7015, Technical Data – Commercial Items.
Prior to contracting for commercial drawings/models, the Procuring Activity should review the drawings/models for their adequacy for the Government's intended uses for the drawings/models. Commercial drawings/models and associated lists should not be acquired as a substitute for product drawings/models and associated lists when the item is developed at Government expense. Commercial drawings/models will most often be ordered under contracts for engineering and manufacturing development or production (including commercial item acquisition).

SIE drawings/models and associated lists (DI-SESS-81004E) are used for the limited production of SIE required to inspect and test a specific hardware system. SIE drawings/models are not adequate to procure and maintain logistic support of standard military inspection systems and test equipment, which are deployed throughout the maintenance and user communities.
This data is intended for use in alternate manufacturing or inspection environments only. If SIE is required for the maintenance and logistics support of the item when deployed, the same types of drawings should be ordered for that SIE as is ordered for the item the SIE supports. SIE drawings/models should only be ordered under contracts containing tasks for engineering and manufacturing development or production. A.2.4.6 Special Tooling (ST) drawings/models and associated lists.
Special tooling drawings/models (DI-SESS-81008E) are used to permit the Procuring Activity or an alternate source to duplicate the functional requirements of tooling that are mandatory for the manufacture of the item. These drawings/models are intended for limited production of tooling used in a manufacturing environment. ST drawings/models may not be adequate to procure and maintain logistic support of tooling which is deployed throughout the maintenance and user communities. If ST is required for the maintenance and logistics support of the item when deployed, the same types of drawings should be ordered for that ST as is ordered for the item the ST supports.
ST drawings/models should be ordered only under contracts containing tasks for engineering and manufacturing development or production. 28
