AS6171 : Test Methods Standard; General Requirements, Suspect/Counterfeit, Electrical, Electronic, and Electromechanical Parts

This document standardizes requirements, practices, and methods for testing EEE parts and detecting Suspect/ Counterfeit parts, to thereby ensure consistency across the supply chain for test requirements.

SAE AS6171 REQUIREMENTS

1.  Risk Assessment – The purpose of risk assessment is to determine the recommended level of testing that should be utilized to manage the risk associated with the use of a part procured through an unauthorized supplier.

2. Test Sequence Overview – The risk assessment models established a tier level methodology based on a risk assessment utilizing a risk analysis of the product, component, supplier, other adjustment factors and an assessment of test coverage based on the known counterfeit defect types from the different test methods in the standard. 

3. Testing Requirements and Minimum Tier Level Testing – If a User organization with a Cognizant Engineer requires a higher tier level of testing than has already been performed on the same lot of parts, then only the additional testing is to be performed.

4. Suspect/Counterfeit (SC) Part Detection Sequence – The SC Parts Detection Sequence has been established based on inspection and testing of parts by selecting the least costly inspections that are most effective, and easiest to perform first, and then to build upon results of previous testing in accordance with the sequence to build confidence in the results.

5. Sampling Plan – The sampling plan is derived from the General Specification for Microcircuits, MIL-PRF-38535. No indications that the part is suspect counterfeit are allowed. If such an indication is detected and a part is determined to be a suspect/counterfeit part, then this part is considered to have failed the test and the testing of the lot shall be halted. Upon notification, the Requester will have the option to resume testing.

6. Test Plan –When required by the Requester: A Test Plan shall be generated by the Test Laboratory to document how it plans to implement the requested SOW and/or PO. A device-specific Test Plan should be agreed upon between the Requester and Test Lab before testing is initiated.

7. Analysis and Interpretation of Test Results – An important constituent of the CP Inspection/Screening process is for the Test Laboratory to analyze the test results in order to prepare the final report. This effort should be made in consultation with the Requester and when possible the User, if there is an indication of suspect/counterfeit part(s). This consultation effort is important in the event a suspect counterfeit part is discovered. This situation may require additional verification testing or documentation, if requested by the Requester or User.

8. Test Report – The Test Report shall be generated by the Test Lab Engineer to document how the Test Laboratory followed the Test Plan to implement the requested counterfeit parts inspection request from the Requester.

9. Training, Qualification, and Certification – All Personnel performing work affecting product quality shall be competent on the basis of appropriate education, training, skills and experience.

10. Data and Report Retention Requirements – The Test Laboratory is to observe the following requirements in the recording and retention of test data and test reports: Recording of data shall be in conformance with the request from the Requester. All test data and test reports supplied to the Requester shall be retained by the Test Laboratory for a minimum of 10 years, or longer if specified by agreement with the Requester, in a manner to protect against damage from fire, flood, and other environmental hazards.
