Rejection Criteria
Conditions and thresholds that trigger immediate rejection or downgrading.
All-aluminum radiator OR all-copper radiator OR unknown composition
Reclassification to appropriate grade or rejection
- Material Type Misidentified
- Must Be Confirmed Mixed-Metal Radiator For Processing Specifications
Visual inspection + XRF analysis
CRITICAL - MATERIAL TYPE VIOLATION
- Reclassified To Pure Aluminum/Copper Commodity Or Rejected
- Significant Value Loss If Misgraded
Cu <20% OR Cu >50%
Reclassification or rejection
- Composition Inconsistent With Mixed-Metal Radiator Specification
- Processing Value Mismatch
XRF spectrometry (authoritative)
CRITICAL - COMPOSITION VIOLATION
- Material Reclassified To Alternative Commodity Grade Or Rejected
- Value Adjustment Applied
Al <40% OR Al >70%
Reclassification or rejection
Composition inconsistent with radiator specification
XRF spectrometry
CRITICAL - COMPOSITION VIOLATION
- Reclassification Or Rejection
