Required Test Methods
Visual Inspection
Purpose
- Confirm predominantly copper
- assess contamination level
- detect major hazards
Acceptance Criteria
- Pass: Predominantly copper appearance
- solder/paint acceptable
- NO radioactive/asbestos
Procedure
- Visual scan
- gross contamination check only
Magnetic Test
Purpose
- Exclude stainless steel/ferrous mixing
Acceptance Criteria
- Pass: Weak or moderate magnetic response acceptable (ferrous tolerance)
XRF Spectrometry
Purpose
- Estimate Cu ≥90%, total contaminants <10%
Acceptance Criteria
- Pass: Cu 90–100%
- combined contaminants <10%
Quick Assessment Test
Purpose
- Rapid purity estimate (visual + weight)
Acceptance Criteria
- Pass: Material appears predominantly copper
