Required Test Methods
Visual Inspection
Purpose
- Confirm brass/copper radiator (NOT aluminum)
- verify radiator condition
- assess structural integrity
- detect hazmat indicators
Acceptance Criteria
- Brass-colored fins and copper-colored tubes apparent (NOT aluminum silver appearance)
- structural integrity reasonable
- no obvious hazmat warning signs
Procedure
- 100% visual scan
- confirm material type (brass/copper vs. aluminum)
- assess radiator condition
- identify damaged units
- note fluid residue levels
Material Type Identification
CRITICAL
Purpose
- distinguish brass/copper radiator from aluminum radiator (different recycling stream)
Acceptance Criteria
- Brass/copper radiator confirmed (NOT aluminum)
- material type clear
Fin/Tube Composition Assessment
Purpose
- Verify brass fins and copper tubes
- assess component separation feasibility
Acceptance Criteria
- Brass fins identifiable (yellowish)
- copper tubes identifiable (reddish)
- separable or already separated
Procedure
- Visual inspection of fin/tube construction
- assess brazed/soldered joint condition
- determine separation difficulty
Coolant/Fluid Assessment
Purpose
- Evaluate residual coolant/fluid
- assess drying status
- identify hazardous fluid
Acceptance Criteria

- asbestos risk assessed
- lead assessment completed
Procedure
- Visual age indicators (design, construction)
- historical source documentation
- expert assessment if pre-1980
Structural Integrity Check
Purpose

Procedure
- Visual inspection
- gentle pressure test (confirm no active leaks)
- damage documentation
XRF Spectrometry
Purpose
- Verify Cu 70-85% blended
- confirm Zn 10-25%
- assess contamination (Pb, Fe, Sn)
Acceptance Criteria
- Cu 70-85%, Zn 10-25% (radiator blended spec), Pb <1.5%, Sn <0.8%, Fe <1.0%
