AS6462D, as the supporting verification standard for AS5553C, entered a stable state after being revised in 2019.
| Version | Major Changes | Technical Highlights |
|---|---|---|
| AS6462C | Basic Verification Requirements | Basic Testing Process |
| AS6462D | Integration into AS5553 System | In-depth Supply Chain Traceability |
The standard requires the establishment of a hierarchical procurement strategy:
An avionics manufacturer implemented clause 3.1.3.e of AS6462D to establish the following inspection process for FPGA chips purchased from the second-hand market:
| Document type | Preservation requirements | Associated clauses |
|---|---|---|
| Supplier authorization certificate | 10 years | 3.1.3.b |
| Risk mitigation records | Product life cycle + 5 years | 3.1.5 |
The standard specifically points out the need for attention:
Q: How to define "authorized source"?
A: According to the definition of AS5553C, including the original manufacturer and its authorized first-tier distributors, a valid authorization chain certificate must be provided.
Q: Is the standard applicable to military equipment?
A: Yes, the standard has been adopted by the DoD as the basic specification for supply chain management and must be implemented in conjunction with the provisions of DFARS 252.246-7007.
