Section 2 - Drawing/Data Elements & Management - Reviewing Control Drawings.

2.50 Reviewing Control Drawings.

2.50.1 Vendor Item Control Drawing (VICD).  (Formerly Specification Control Drawing (SCD.)

2.50.1.1 Criteria For Designation.  To qualify as a VICD, the item depicted must meet the following criteria:

1. It must be of an unmodified commercial type, available to both Government and industry on an unrestricted basis.
2. The item must not have been developed for use in the equipment represented by the drawing package under review.
3. The manufacturer’s name, addresses, identification codes and item identification numbers must be shown on the VICD.
4. The drawing must list two or more known sources.

2.50.1.2 Reviewing VICDs.  Analyze VICDs for the following Information:

1. They shall disclose, as applicable, item configuration, envelope dimensions, mounting and mating dimensions, interface dimensional characteristics, and their limits.
2. The VICD must show inspection and acceptance test requirements, performance reliability, maintainability, environmental and other functional requirements as necessary to ensure identification and adequate competitive procurement of an interchangeable item.
3. If an electrical, electronic, or other engineering circuit is involved, a schematic connection or other appropriate drawing shall be included or referred to by the drawing to provide sufficient information to mark external connections.
4. VICD numbers are administrative control numbers and shall not be marked on the part.  The VICD numbers are used to identify the item on other drawings or documents.
5. Qualification testing of items in advance of procurement action is not a prerequisite for including an item on a VICD.
6. If a decision cannot be made from the information available, the manufacturer of the item or activity submitting the drawing should be contracted to verify that the item meets the criteria for a VICD.
7. All sources of supply should be checked to verify that the part numbers listed on the drawing correspond to the item depicted on the drawing and are currently available.
8. The manufacturer’s part number becomes the item’s identification number.
9. The notations “VENDOR ITEM CONTROL DRAWING” and “IDENTIFICATION OF SUGGESTED SOURCES OF SUPPLY” must appear on the drawing per ASME Y14.100 and Appendix D.  
10. VICD numbers are not marked on the parts.

2.50.2 Source Control Drawings (SOCD).

2.50.2.1 Criteria for Designation.  A SOCD defines an item which is procurable only from certain vendors for reasons such as the following:

1. A vendor has a special technique which will make the vendor’s product work in a system where others will not. The key elements may be identifiable.
2. There is a specific critical application in which substitute vendors shall not be used without prior testing evaluation, and approval. Critical factors may include performance, installation, interchangeability or reliability and must be specified on the drawing.
3. The notation “SOURCE CONTROL DRAWING” must be on the drawing. See ASME Y14.100 and Appendix D. 

2.50.2.2 Reviewing SOCDs. SOCD requirements are identical to those for VICDs except for the following differences.

1. Items must be tested and prequalified for inclusion in SOCDs.
2. The drawing shall include the following notes:
   Note 1:  ONLY THE ITEM DESCRIBED ON THIS DRAWING, WHEN PROCURED FROM THE VENDORS(S) LISTED HEREON IS APPROVED BY (Name and address of the cognizant 
   design activity) FOR USE IN APPLICATIONS(s) SPECIFIED HEREON. A SUBSTITUTE ITEM SHALL NOT BE USED WITHOUT PRIOR APPROVAL BY (Name of cognizant design activity) OR BY (Name of Government procuring activity).
   Note 2: IDENTIFICATION OF THE APPROVED SOURCES(S) HEREON IS NOT TO BE CONSTRUED AS A GUARANTEE OF PRESENT OR CONTINUED AVAILABILITY AS A SOURCE OF SUPPLY FOR THE ITEMS DESCRIBED ON THE DRAWING.
3. The drawing shall list under the heading “APPROVED SOURCES OF SUPPLY”, the manufacturer’s name, address, and CAGE Code, as well as the part number of each item that has been tested and approved for use in the specific applications stated on the drawing.
4. Whenever another vendor’s item is tested and is qualified for the stated applications or when a new critical application is found and all vendor items that are cited on the drawings are approved for use in the new critical application, the drawing may be revised to show the new vendor or application. Each new vendor added must be approved for all stated applications.
5. SOCD numbers become the part identification numbers and are subsequently used to identify the item on other drawings or documents.  When more than one vendor is listed on a SOCD for items that are repairable and the repair parts are not interchangeable between one vendor’s item and another, each vendor’s item shall be assigned a unique suffix of the SOCD number.
6. Ensure that the “SOCD” and the drawing number are marked on the part. The SOCD number becomes the item’s part number. Reference ASME Y14.100 and Appendix D.

2.50.3 Selected Item Drawings.  Selected item drawing disclosure requirements are identical to those of VICDs except for the differences listed below:

1. The drawing must contain the notation “SELECTED ITEM DRAWING”.
2. Complete details of the selection criteria shall be described, such as fit, tolerance, performance and reliability.
3. When a vendor document is referred to in the selected item drawing, it shall be submitted with the drawing package.  If the document is unobtainable, the selected item drawing shall contain sufficient information to identify that item before selection.
4. The part number and the manufacturer’s name, address and identification number shall be included in the drawing package.
5. The original part number must be obliterated, and the selected item drawing number shall become the part number of the selected item itself. See ASME Y14.100-2004 and Appendix D.

2.50.4 Altered Item Drawings.  Altered item disclosure requirements are identical to those of VICDs and Selected Item Drawings except for the differences listed below:

1. The drawing shall include information necessary to identify the item prior to its alteration, including the original part number and the name and address of the original source.  The name and address of the source need not be furnished if the original part is a government or industry standard item.  
2. When a vendor activity document is referred to, the vendor data shall be submitted along with the altered item drawing. If the vendor or original design data is unobtainable, the Altered Item Drawing shall contain sufficient information to identify that item prior to its alteration.
3. The notation “ALTERED ITEM DRAWING” must appear on the drawing.
4. The original part number must be obliterated.
5. Altered Item Drawing numbers shall become the part numbers of the altered items. Reference ASME Y14.100 and Appendix D.
