Required Test Methods
Visual Inspection
Purpose
- Confirm mixed aluminum-copper radiators (not all-aluminum, not all-copper, not ferrous)
- verify copper tubes/aluminum fins visible
- assess condition
Acceptance Criteria
- Copper tubes/core visually apparent
- aluminum fins evident
- mixed-metal construction confirmed
- no heavy ferrous mixing
- condition assessed as acceptable
Procedure
- 100% visual of all samples
- verify radiator type (mixed vs. monolithic)
- identify radiator age/source if possible
- assess surface corrosion, leaks, damage
- confirm non-ferrous character
Magnetic Test
Purpose
- Exclude ferrous contamination or steel radiator mixing
- verify mixed-metal non-ferrous character
Acceptance Criteria
- Minimal magnetic response (aluminum/copper non-magnetic)
- strong magnetism flags ferrous contamination
Procedure
- Magnet test on sample radiators (minimum 10-20 samples)
- confirm non-ferrous primary composition
- strong magnetic response triggers investigation
Copper-Aluminum Ratio Assessment
CRITICAL
Purpose
- estimate copper percentage (20-50% specification)
- assess aluminum component (40-70%)
- verify mixed-metal specification compliance
Acceptance Criteria
- Copper tubes visible and prominent
- aluminum fins/core evident
- ratio appears within 20-50% copper range
- mixed-metal specification confirmed
Procedure
- Visual copper tube identification
- comparative measurement
- XRF elemental analysis for quantification
- confirm radiator specification compliance
Solder/Brazing & Joint Assessment
Purpose
- Evaluate solder/brazing residue and radiator joint condition
- assess construction integrity
Acceptance Criteria
- Solder/brazing visible at radiator joints
- joint construction acceptable
- no major cracking or leaking indicators
Procedure
- Visual inspection of radiator end tanks and tube joints
- check for weeping leaks, solder failures, brazing integrity
- assess repair history if apparent
Coolant Residue & Structural Damage Check
Purpose
- Evaluate coolant contamination levels
- assess radiator structural integrity
- identify leaking/damaged units
Acceptance Criteria
- Coolant residue <3%
- radiator structurally intact
- no major leaks or corrosion damage (>20% damage)
- minor corrosion acceptable
Procedure
- Visual/olfactory assessment (coolant odor)
- inspect for active weeping leaks, corrosion pitting, tube degradation
- measure corrosion damage percentage
- assess structural soundness
XRF Spectrometry
CRITICAL
Purpose
- Verify Cu 20-50% and Al 40-70% ()
- assess all contamination (Pb, Sn, Fe, other)
- confirm mixed-metal specification
Acceptance Criteria
- Cu 20-50%, Al 40-70%, Pb <1%, Sn <2%, Fe <2%, Brass <10%, all others combined <3%
