Rejection Criteria
Conditions and thresholds that trigger immediate rejection or downgrading.
Material NOT confirmed as 2000 or 7000-series aerospace alloys
IMMEDIATE FULL REJECTION
- Aerospace Specification Violated
- Wrong Alloy Category
- Zero Tolerance For Non-Aerospace Materials
XRF spectrometry + alloy series confirmation
CRITICAL - AEROSPACE SPECIFICATION VIOLATION
- Material Cannot Enter Aerospace Supply Chain
- Downgraded To Commodity Aluminum Scrap (90%+ Price Loss)
CoC missing OR documentation cannot be verified OR signatures appear forged/questionable
- Immediate Full Rejection
- Suspect Material Quarantine
- Traceability Critical For Aerospace
- Authenticity Unconfirmed
- Regulatory Violation Risk
- Potential Counterfeit Material
- Document Verification
- Signature Chain Analysis
- Cross-Reference With Aerospace Supplier Records
CRITICAL - REGULATORY & AUTHENTICITY
- Material Quarantined
- Cannot Be Released
- Potential Law Enforcement Notification If Forgery Suspected
ANY element exceeds AMS specification limit
- No Partial Acceptance
- No Credit
- Aerospace Zero-Defect
- Single Element Violation = Structural/Safety Concern
- Unacceptable Risk For Aerospace Applications
ICP-AES spectrometry (authoritative test)
CRITICAL - AEROSPACE SAFETY
