1、 TechAmerica Engineering Bulletin TechAmerica-TB-0003 Counterfeit Parts therefore we must fix how we buy and what we buy. The G-12 Counterfeit Task Group has unanimously agreed that: The only control or safeguard to protect your Program from todays sophisticated counterfeiters is to only procure fro

2、m the Original Equipment Manufacturer (OEM) that makes and warranties the part or material, or their designated franchisees. All other procurement approaches offer significant risk to the Program. Any part or material that has been out of the OEMs authorized supply chain has some risk of not fulfill

3、ing its intended mission objectives.

4、 2 Copyright Government Electronics for example, it may not identify a fraudulently labeled part, e.g. a commercial part relabeled as a military temperature range part. The evaluation methods used both from Table 1 and other techniques should be selected based on a parts technology, physical and ele

5、ctrical characteristics and the reason for suspicion. When a counterfeit part or material is confirmed: a. Segregate the counterfeit item, and it is suggested that the item not be returned to the supply chain. b. Review the evidence with procurement and investigative organizations. c. Try to procure

6、 the authentic part or material directly from the OEM or their franchised/authorized distributor. (Franchised or authorized distributors may be found by contacting the OEM who manufactures and warranties the parts or materials.) This will help support the Program schedule. d. Contact GIDEP or follow

7、 Program guidelines to report the problem. e. If no bonafide OEM parts or materials can be procured to support the Program objectives, notify the Program and consider redesigning the system. To report a problem through the GIDEP system, GIDEP participants should submit a GIDEP report in accordance w

8、ith GIDEP instructions. Non-participants can contact the GIDEP Help Desk (915-818-3207) for guidance. 5 Copyright Government Electronics & Information Technology Association Provided by IHS under license with GEIA Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-Tec

9、hAmerica-TB-0003 5 Risk Mitigation When no alternatives exist except a full redesign and the Program has directed the use of an item obtained from an unauthorized source, a process should be followed to assess Program requirements and to mitigate some of the risk of the items use. Since risk mitigat

10、ion is expensive and time consuming, the Program must determine the amount of risk it can afford to retire, understanding that it is impossible to eliminate all risk of use. As with the detection methods discussed in Section 4, this process will not guarantee an items suitability for the Programs ap

11、plication, it will only either identify some risks or improve the confidence that the item will fulfill its intended purpose. The same methods identified in Section 3, Table 1, and the techniques outlined in Figure 1 provide guidelines in developing a risk mitigation plan. The items characteristics

12、(physical, electrical, mechanical, construction, materials, etc.), application (including environmental) and required reliability (expected service life, ability to be replaced after failure, etc.) must all be considered in developing and implementing a plan. Cost, schedule and the risk of both fail

13、ing to detect a deficiency and in damaging a “good” part are also considerations. A risk mitigation process should include the following actions: a. Identify to the Program the risks associated with the items use, any redundancy factors, and the plan to verify the items suitability for its intended

14、application. See Section 1, use of a non-authorized supplier, for ideas on what a plan should include. b. Obtain the Programs (customers if necessary) approval to proceed with the evaluation plan. c. Conduct the planned evaluation to mitigate some of the risks. d. The procurement of a large quantity

15、 of parts will be necessary to give any confidence in a lot of parts or materials that is procured from a source other than the manufacturer of the product. e. A Destructive Physical Analysis (DPA) should be conducted in accordance with MIL-STD-1580 on a random sample with a minimum of a 90% confide

16、nce level (i.e. 22 piece sample, C =0) at a program approved laboratory. A sample (22 pieces) should be selected from each lot / date code. f. The results of all tests, evaluations and investigations should be carefully reviewed to identify any evidence of defects that jeopardize the items use in it

17、s intended application. Any new risks should be reported to the program. 6 Copyright Government Electronics & Information Technology Association Provided by IHS under license with GEIA Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-TechAmerica-TB-0003 7 Add materi
