AS6171 Information contained in the above is the property of the Copyright holder and all Notice of Disclaimer General Requirements, Suspect/Counterfeit, Electrical, Electronic, and Electromechanical Parts RATIONALE This standard was created in respo
7、nse to a significant and increasing volume of Suspect/Counterfeit (SC) Electrical, Electronic, and Electromechanical (EEE) parts entering the aerospace supply chain, posing significant performance, reliability, and safety risks. This standard was created to provide uniform requirements, practices an
8、d methods for testing EEE parts to mitigate the risks of receiving or using SC EEE parts. FOREWORD To assure customer satisfaction, industry organizations must produce, and continually improve, safe, reliable products that meet or exceed customer and regulatory authority requirements. The globalizat
9、ion of industry and the resulting diversity of regional/national requirements and expectations has complicated this objective. End-product organizations face the challenge of ensuring the quality and integration of products purchased from suppliers throughout the world and at all levels within the s
10、upply chain. Suppliers and processors face the challenge of delivering products to multiple customers having varying quality expectations and requirements. This document standardizes requirements, practices, and methods for testing EEE parts and detecting Suspect/Counterfeit parts, to thereby ensure
11、 consistency across the supply-chain for test requirements. SAE INTERNATIONAL AS6171 Page 2 of 102 TABLE OF CONTENTS 1.

SCOPE 1.1 Purpose This SAE Aerospace Standard (AS) standardizes inspection and test procedures, workmanship cr
23、iteria, and minimum training and certification requirements to detect Suspect/Counterfeit (SC) Electrical, Electronic, and Electromechanical (EEE) parts. The requirements of this document apply once a decision is made to use parts with unknown chain of custody that do not have pedigree back to the o
24、riginal component manufacturer, or have been acquired from a broker or independent distributor, or when there are other known risk elements that result in the User/Requester to have concerns about potential SC EEE parts. The tests specified by this standard may also detect occurrences of malicious t
25、ampering, although the current version of this standard is not designed specifically for this purpose. This standard ensures consistency across the supply chain for test techniques and requirements based on assessed risk associated with the application, component, supplier, and other relevant risk f
26、actors. The requirements of this document supplement the requirements of a higher level quality standard (e.g., AS9100, AS9003, AS9120, ISO 9001) and other quality management system documents. They are not intended to stand alone, supersede, or cancel requirements found in other quality management s
27、ystem documents, or requirements imposed by contracting authorities. This standard should be implemented when other risk mitigation methods for avoiding the use of SC EEE parts (e.g., acquiring all parts from Authorized Sources, redesigning the system, having obsolete parts emulated, etc.) are eithe
28、r unavailable or inadequate. This standard mitigates the technical risk of performing insufficient inspection and test to determine suspect counterfeit EEE parts. This standard is not intended to be used to assess quality or reliability issues that may arise because of component production issues or
29、 due to mishandling, improper storage, or other attributes specific to quality or reliability. The following terminology is used throughout this document and associated AS6171 Slash Sheets: a. Shall = is mandatory; b. Should = is recommended; and c. Will = is planned (is considered to be part of a s
30、tandard process). This standard should be utilized when parts are not available from sources with known traceability to the Original Component Manufacturer (OCM), Original Equipment Manufacturer (OEM) for electromechanical parts, or authorized manufacturer. The requirements of this document specify
31、testing based on acceptable levels of risk for a program or customer, to identify anomalies or performance issues that may indicate suspect counterfeit and counterfeit activity. No amount of testing can confirm an item as authentic; this would require that there be a known, unbroken chain of custody
32、 to the OCM/OEM or authorized manufacturer. Therefore, organizations should attempt to obtain parts from sources that have known traceability to the OCM or authorized manufacturer to avoid receiving counterfeit parts. All intermediaries from the origin (i.e., OCM/OEM or authorized manufacturer) to t
33、he final destination should consist of Trusted Suppliers, and transportation should be provided by logistics carriers that have documented processes and procedures to avoid tampering or substitution during the journey to the parts final destination. A preference should be given to parts with known p
34、edigree over parts with unknown pedigree to avoid counterfeit parts. This standard does not apply to parts obtained directly from a Trustworthy Authorized Supplier with traceability to the OCM/OEM or authorized manufacturer. This standard does not have specific test methods to determine if an item i
35、s a Fraudulent Part beyond what is considered counterfeit. Test data on anomalies can be gathered for potential legal determination of fraudulent intent or negligence. This document does not make a legal determination of fraud, and appropriate legal counsel should be consulted for further action. Un
36、less otherwise specified in the SOW or PO by the User/Requester, the information in the Appendices is not considered mandatory. SAE INTERNATIONAL AS6171 Page 5 of 102 1.2 Application This document is intended for use in aviation, space, defense, and other high performance/reliability electronic equi
37、pment applications. Any other sector that is at risk for counterfeit EEE parts could adopt this standard to mitigate the concern. This standard is recommended for use by all contracting organizations that procure EEE parts and devices, whether such parts and devices are procured directly or integrat
38、ed into procured electronic assemblies or equipment. The requirements of this standard are generic and intended to be applied/flowed down to all organizations that procure EEE parts and devices. 1.3 Product Classification This standard applies to the Electrical, Electronic, and Electromechanical (EE
39、E) parts and devices that are outlined in the Applicability Matrix in Appendix A, Table A1. The test methods to be used in evaluating the part types are based upon inspection for material, construction, and function. Although the AS6171 test methods are not specifically designed to evaluate all EEE
40、parts, some of the evaluation techniques may be employed to investigate the authenticity of certain EEE parts. 1.3.1 Programmable Devices In the case of a programmed or programmable device containing non-volatile memory supplied to the Test Laboratory for evaluation, the Test Laboratory shall determ
41、ine if the device is programmed as directed by test requirements through a statement of work. If known, the User/Requester should indicate to the Test Laboratory if the part is programmed. If there is advanced knowledge that the part is programmed, the Cognizant Engineer should notify the Test Labor
42、atory with instruction on how to proceed. The programmed state of the device and the programmed device test method should be supplied to the Test Laboratory in the Test Requirements as part of the statement of work. The Test Laboratory shall indicate in the test report if they conducted a test for p
43、rogrammability or if the test laboratory has knowledge that the parts are programmed (e.g., the User/Requester indicated the parts are programmed). 2.
