A.

This information pertains to items identified as Critical or Critical Safety Item (CSI). These alternate source approval procedures apply only to new, manufactured items.

1. ASME Y14.100 defines a Critical or Critical Safety Item  as:

"A part, assembly, installation or production system with one or more critical characteristics that, if not conforming to the design data or quality requirements would result in an unsafe condition. Unsafe conditions relate to hazard severity categories I and II of MIL-STD-882, System Safety Program Requirements, and include conditions which could cause loss or serious damage to the end item or major components, loss of control or serious injury to personnel."

2. DoD-STD-2101 defines a critical characteristic as:

"A characteristic that analysis indicates likely, if defective, to create or increase a hazard to human safety, or to result in failure of a weapons system or major system to perform a required mission."

3. Every Critical or Critical Safety Item has at least one critical characteristic.

B.
For items not coded full and open competition

Only those sources previously approved by the Government will be solicited. The time required for approval of a new supplier is normally such that award cannot be delayed pending approval of the new source. If you have not been solicited and you can furnish either:

a. proof of your prior approval as a supplier of this item, or similar items satisfactorily for the Government or
b. data showing you have produced the same or similar items satisfactorily for the government or a commercial source, or
c. test data indicating your product can meet service operating requirements or
d. other pertinent data concerning your qualifications to produce the required item

Please forward the information to the address designated in the solicitation.
Please note that if evaluation of your source approval request cannot be processed in time to meet logistics support requirements, award will be made to a currently approved source.
The request will be processed for consideration against future requirements.

Top

C.

Source Approval Categories

There are basically three conditions under which Source Approval Request (SARs) will be categorized:

SAME PART (Category I)
Item previously provided to Original Equipment Manufacturer (OEM).

SIMILAR PART (Category II)
Item is similar to item previously provided to the OEM or Department of Defense (DoD). A similar item in this context is one whose design, application, operating parameters, material, and manufacturing processes required are similar to those of the item for which you are seeking source approval.

NEW MANUFACTURER (Category III)
Manufacturer has not provided any item similar to item being solicited to the OEM or DoD. A similar item in this context is one whose design, application, operating parameters, material, and manufacturing processes required are similar to those of the item for which you are seeking source approval.

D.

If you are a dealer- supplier (non-manufacturing source) of the item for which you are seeking approval, the category to which the actual manufacturer belongs will apply for purposes of approval procedures. The actual manufacturer is defined as that vendor with plant equipment and personnel to manufacture, on the premises, the item for which approval is requested.

Therefore, the name, address and Commercial and Government Entity (CAGE) code of your vendor (actual manufacturer) is required and must be provided for consideration of source approval together with all data supporting the category for which approval applies. The source evaluation/approval procedures apply only to newly-manufactured items.

E.

To reduce the time required for processing a Source Approval Request, it is important to provide ALL of the information at the time of your request.
Submission of the requested information does not guarantee approval.
Submission of a complete Source Approval Request is the best method for obtaining timely review of source approval requests.
Additional information and documentation may be required to allow further evaluation of your request(s).
In some cases, qualification parts may be required as determined by the technical evaluation to be used for testing which may include, but not be limited to, performance and/or endurance testing.
A site visit of your facility may be conducted to evaluate further your capabilities.

 F.

Each  Source Approval Request package shall be limited to one (1) item or assembly per request.
However, for assemblies that contain multiple procurable piece parts, separate SAR package does not need to be submitted for each procurable piece part if all information has been provided with the assembly SAR.

G.

Submission of the requested information does not guarantee approval.
Additional information, documentation or samples may be required in any of the categories to allow for further evaluation of the submitting company’s request for source approval.
Regardless of the category, a site survey visit of the facility may be conducted to further evaluate their capabilities.

H.

The  Source Approval Request information and documentation can be submitted in two formats.
The preferred method for your Source Approval Request documentation is digitally on Compact Disk (CD); for everything except the drawings (checklist elements B & H).
If the data is via a contractor produced CD, we can currently only accept it in .PDF format.
If the CD originated at one of the DoD activities (DLA, Army, Navy, Air Force), format is not an issue
