Quality Assurance
Testing protocols, sampling methods, and acceptance criteria.
Sampling Protocol
frequencyContinuous visual inspection + random testing throughout load
layerSamplingFor pile loads >50 tonnes, sampling from top, middle, and bottom layers
maximumQuantityNo maximum; continuous sampling for very large loads
minimumQuantity1 tonne absolute minimum
notesStrict sampling reflects premium grade requirement; zero-defect quality mandate
percentage5% of lot or 1 tonne minimum, whichever is
Acceptance Limits
all Criteria Must Passcriteria must simultaneously meet thresholds; single criterion failure triggers rejection or credit
copper LimitCu <0.1%
iron ContentFe ≥98.0%
moisture<2%
non Ferrous Total<2.0% combined contaminants
particle Integrity100% solid pieces; no fragmentation or hollow components
stainless Steel<0.05%
surface Condition≤5% light rust acceptable; coatings, tin plate, heavy scale
visual Contaminants≤1% prohibited items observed
Weight Tolerance
notesSolid steel density variation permits ±3% tolerance; measured by truck/container scale
variance±3% acceptable from purchase order weight
Required Test Methods
Visual Inspection
Purpose
- Detect obvious non-ferrous materials, stainless steel, hazardous items
- identify contamination not visible to
Acceptance Criteria
- ≤5% visible rust acceptable
- NO copper, stainless, non-ferrous metals visible
- <1% prohibited items
Procedure
- 100% visual scan of load
- mandatory inspection of top surface, sides, and representative samples from depth
XRF Spectrometry
Purpose
- Elemental composition analysis
- verify Fe ≥98%, Cu <0.1%, non-ferrous <2%
Acceptance Criteria
- Fe ≥98.0%, Cu <0.1%, non-ferrous contaminants <2.0%, stainless <0.05%
Magnetic Test
Purpose
- Confirm ferrous nature
- detect non-magnetic stainless steel contamination
- identify sorting effectiveness
Acceptance Criteria
- All material pieces respond strongly to hand magnet
- NO dead zones or non-responsive pieces
Procedure
- Apply strong neodymium hand magnet to random samples
- all pieces must be attracted immediately
Moisture Content Testing
Purpose
- Verify moisture <2%
- detect potential hazardous water-reactive materials
Acceptance Criteria
- <2% moisture content via Karl Fischer titration or gravimetric analysis
Procedure
- Test on sub-sample if lot appears wet or recently handled in wet conditions
Surface Condition Assessment
Purpose
- Verify no coatings, paint, tin plate present
- confirm clean material
Acceptance Criteria
- No visible paint chips, tin plate residue, or heavy oxide coating
Procedure
- Scratch test on representative sample
- visually inspect cut edges for coating layers
