Required Test Methods
Visual Industrial Board Assessment
CRITICALMANDATORY
Purpose
- confirm industrial-grade boards (not consumer electronics)
- identify equipment source (power supply vs. telecommunications vs. automation)
- assess composition variability and hazmat risk profile
Acceptance Criteria
- Industrial board characteristics unmistakably evident
- heavy copper/industrial components visible
- equipment type recognizable
- industrial-grade specification apparent
Procedure
- 100% visual inspection
- identify industrial board characteristics (heavier traces, industrial connectors, specialized component density, professional layout)
- assess equipment application from board design
- estimate board age/standards compliance
- preliminary hazmat assessment from solder appearance (dull gray = lead-based
- shiny = lead-free)
Equipment Type & Source Classification
CRITICAL
Purpose
- categorize by equipment source (power supply/telecommunications/industrial automation/specialized)
- estimate precious metal composition
- assess hazmat risk profile
- authenticate industrial status
Acceptance Criteria
- Equipment type clearly identified
- board classification confirmed
- precious metal profile estimated
- hazmat risk profile established
Procedure

- detect palladium/platinum trace if present
- establish precious metal recovery yield
Copper & Heavy Component Assessment
Purpose
- Quantify copper 30-150g (INDUSTRIAL
- often 2-3× consumer boards)
