Rejection Criteria
Conditions and thresholds that trigger immediate rejection or downgrading.
>0.15%
REJECTION (relaxed vs. HMS #1 which is <0.10%)
- Copper >0.15% Affects Eaf Steel Ductility
- #2 Hms Allows Higher Limit Due To Light Gauge Nature
XRF spectrometry
CRITICAL
>0.1% detected
REJECTION
- Austenitic Stainless Degrades Ferrous Steel Quality
- Indicates Inadequate Sorting
XRF + magnetic test
CRITICAL
>5% by weight (Zn source)
Rejection or credit negotiation based on Zn % verification
- Excessive Galvanized Coating Increases Zinc Contamination
- Reduces Final Steel Properties
XRF spectrometry (zinc measurement)
MAJOR
>2.5% combined (higher tolerance than HMS #1 at 2.0%)
Rejection or credit adjustment
Light gauge scrap permits higher non-ferrous tolerance than solid HMS
XRF spectrometry
MAJOR
>2% moisture
Re-dry and re-test or rejection
- High Moisture In Thin Material
- Unacceptable For Eaf Melting
Karl Fischer titration
MAJOR
Fe <97.5%
REJECTION
Violates ISRI 202 minimum specification
XRF spectrometry
CRITICAL
Any visible strands >0.5mm diameter
- Manual Removal Required
- Possible Rejection If Excessive
Copper wire indicates incomplete separation
