A.1 NPR 7120.5, NASA Space Flight Program and Project Management Requirements.
A.2 NPR 8705.4, Risk Classification for NASA Payloads.
A.3 NASA Parts Selection List (NPSL): http://nepp.nasa.gov/npsl.
A.4 NASA Tin and Other Metal Whisker website: http://nepp.nasa.gov/whisker.
B.1 Tin-Lead (Sn-Pb) based solders and Sn-Pb part surface finishes (minimum 3% Pb by weight) will be used for the assembly of electronics hardware intended for NASA spaceflight and critical ground support applications. The use of lead-free (Pb-free) solders or Pb-free Sn-based part surface finishes may be allowed when justified by technical need, but only by exception and with the approval of the parts, materials, and processes control board for the NASA project or an equivalent authority.
B.2 The use of Pb-free (<3% Pb) Sn-based solders and surface finishes in applications below 13.2oC are assessed for the risk of the damaging effects of tin pest formation. Tin pest refers to the allotropic phase transformation of tin that can occur which turns tin from a ductile conductor into a brittle semiconductor.
Note: The introduction of lead containing solders presents an employee exposure hazard that is regulated under OSHA (29 CFR 1910.1025). This regulation requires baseline hazard assessments be performed for any operation (e.g., generation of metal dust or fume) that may result in employee exposure to lead, and additional medical surveillance, employee training, monitoring, and exposure control requirements when a positive exposure assessment is made. Exposure risk, based on past assessments, is very low for piecework operations and moderate for assembly line or classroom instruction based on work volume.
B.3 Regardless of the exposure assessment outcome, all affected employees are required to complete Hazard Communication training for Chemical Users and individual employee review of 29 CFR § 1910.1025, Appendix A, "Substance data sheet," and B, "Employee Standard Summary." This training may be provided at the supervisory level by employee review of the referenced appendices available from Environmental Health. Additionally, all soldering workstations will require use of local exhaust ventilation (fume extractors) and regular cleaning to prevent buildup of lead residue on work surfaces.
C.1 Parts Availability Process:
a. Maximize availability of authentic, originally designed, and qualified parts throughout the product's life cycle, including, for example:
(1) Control of parts obsolescence.
(2) Alternate/multiple sources.
(3) Acceptable product substitutions.
(4) System redesign.
(5) Inventory control, parts sparing, and/or lifetime buy practices.
(6) Planning for adequate procurement lead times in support of manufacturing and delivery schedules.
C.2 Procurement Process:
a. Assess potential sources of supply to determine the risk of receiving non-authentic parts. Original Component Manufacturers (OCM), OCM-authorized suppliers (e.g., franchised distributors), and authorized aftermarket manufacturers are considered to have low risk of supplying non-authentic parts. Assessment actions include surveys, audits, review of product alerts (e.g., GIDEP), and analysis of supplier quality data to determine past performance. (Note: GIDEP product alerts are accessible through NASA's Supplier Assessment System (http://sas.nasa.gov).)
b. Mitigate risks of procuring counterfeit parts from sources other than OCMs or authorized suppliers.
c. Factor risk of receiving nonauthentic parts into the source selection process.
d. Ensure that approved/ongoing sources of supply are maintaining effective processes for mitigating the risks of supplying counterfeit parts.
e. Include applicable contract/purchase order quality requirements related to counterfeit parts prevention. Examples of quality requirements include:
(1) Certificate of Conformance.
(2) Mandatory Product Tests and Inspections.
(3) Supply Chain Traceability.
(4) Federal Penalties Associated with Fraud and Falsification.
f. Specify contractor flow down of applicable counterfeit parts prevention requirements to their subcontractors.
C.3 Product Assurance Process:
Verify receipt of authentic conforming parts, commensurate with product risk. Product risk is determined by the criticality of the part and the assessed likelihood of receiving a nonauthentic part. Product assurance actions include review of data deliverables, verification of purchase order quality clause compliance, visual inspection, measurements, non- destructive evaluation (e.g., x-ray, hermeticity, marking permanency) and destructive testing (e.g., destructive physical analysis, thermal cycling, construction analysis).
C.4 Material Control and Disposition Process:
a. Identify and quarantine suspect or confirmed counterfeit parts.
b. Confirm conclusively whether the parts are authentic or counterfeit. This may include further part-level testing or communication with the parts' (supposed) OCM.
c. Upon confirmation that a part is counterfeit, identify and place on "Hold" all potential additional counterfeit parts in storage and identify installed counterfeit parts pending disposition by appropriate authorities.
d. Destroy, and/or submit to investigative authorities confirmed counterfeit parts. Counterfeit parts should only be returned to suppliers under controlled conditions so as to prevent their re-entry into the supply chain.
C.5 Reporting Process:
Report nonconforming, defective, and/or suspected counterfeit parts in accordance with NPR 8735.1, and for all cases involving counterfeit parts or other potential fraud, to the NASA Office of Inspector General and the NASA Director, Acquisition Integrity Program.
