Iec 62309 Ed. 1.0 B-2004- Dependability Of Products Containing Reused Parts - Requirements For Functionality And Tests May 2026

If a reused part fails any test equivalent to a new part’s acceptance criteria, it must be rejected or downgraded (e.g., to a lower performance grade or spare part use only). 5.1 Unknown Usage History – The greatest challenge. Without accurate field data, stress from overvoltage, ESD, or moisture cannot be fully simulated. The standard allows risk-based sampling but does not mandate life modeling.

– For obsolete components, reused parts may be the only option. IEC 62309 provides a defensible qualification path, but residual life estimation remains probabilistic. If a reused part fails any test equivalent

– Extensive testing may exceed the cost of new parts, especially for low-value components. The standard is most beneficial for high-reliability or high-cost parts (e.g., aerospace, medical, industrial drives). stress from overvoltage
