MIL-HDBK-115 Us Army Reverse Engineering Handbook Guidelines And ProceduresThis HANDBOOK, which provides the guidelines and procedures for performing reverse engineering, was created using current applicable laws and knowledge gained during a trial program from July 1985 to April 1987, and is based on experiences obtained from military and industry participants. This handbook is for guidance only and cannot be cited as a requirement.

MIL-HDBK-115B(ARMY) APPENDIX C

C.4.3.3 Altered item drawing. The design activity responsible for an alteration to a completed item prepares an Altered Item Drawing. (When a vendor activity document is referenced, the vendor data is submitted along with the Altered Item Drawing. If vendor or original design activity data is unobtainable, the Altered Item Drawing should contain the necessary information required to define the requirements for that item before its alteration.) An Altered Item Drawing delineates complete details on the alteration. The drawing should include the necessary information for identifying the item before its alternation, including the original identifying part number and, if it is a commercially or vendor developed item, the name (address if known), and manufacturer's CAGE number

of the source of the original part. The name and address of the source do not need to be furnished if the original part is a Government or industry standard item. The notation "ALTERED ITEM DRAWING" should appear adjacent to the title block.

NOTE: Alterations may be shown on detail assembly drawings in lieu of a separate drawing, providing the above requirements are met and the altered item is noted as an "ALTERED ITEM."

C.4.3.4 Selected item drawing. A selected item drawing defines an existing standard or design or vendor activity item with further required selection or restriction of the item for fit, tolerance, performance, or reliability within the range or limits prescribed for that item. (When a vendor activity document is referenced, the vendor data is submitted along with the selected item drawings. If vendor or original design activity data is unobtainable, the Selected Item Drawing contains the necessary information required to define the requirements for that item prior to selection.) Although physical modification is not performed on the item, by virtue of the selection technique employed, it is demonstratively different than those identified on the document from which selection was made. In addition, the drawing should include all necessary information to identify the

item prior to its delimited selection including the original identifying part number and, if it is a commercially or vendor developed item, the name (address if known), and manufacturer's CAGE number of the original source. The notation "SELECTED ITEM DRAWING" should appear adjacent to the title block.

C.4.3.5 Associated parts list. A parts list is a tabulation of all parts and bulk material (except those materials which support a manufacturing process) used in the item to which the list applies. The parts list may be integral or separate from the drawing. Generally, engineering drawings for electronic components such as transmitters, receivers, and power supplies are prepared with a separate parts list. When separate parts lists are required, a note "SEE SEPARATE PARTS LIST" should be located above the title block

of the parent engineering drawing. ASME Y14.34 may be used as a guide preparing a parts list.
