Rejection Criteria

Conditions and thresholds that trigger immediate rejection or downgrading.

Copper content out of red brass range
Threshold

Cu <85% OR Cu >95%

Action

AUTOMATIC FULL REJECTION or major reclassification

Reason
  • Critical: Red Brass Definition Requires 85-95% Copper
  • Material Must Be Within Specification
Test Method
  • Authoritative
  • Multi-Point Verification
Severity

CRITICAL - MATERIAL SPECIFICATION VIOLATION (ABSOLUTE)

Consequence:
  • Full Rejection
  • Material Fundamentally Wrong
  • May Reclassify To Yellow Brass Or Pure Copper
Zinc content out of red brass range
Threshold

Zn <5% OR Zn >15%

Action

AUTOMATIC FULL REJECTION or major reclassification

Reason
  • Pure Copper If <5%
  • Yellow Brass If Wrong Ratio
Test Method

XRF spectrometry

Severity

CRITICAL - MATERIAL SPECIFICATION VIOLATION (ABSOLUTE)

Consequence:
  • Full Rejection
  • Material Wrong Type
Lead contamination excessive
Threshold

Pb >1.0% (ANY EXCESS violates strict specification)

Action

AUTOMATIC FULL REJECTION

Reason
  • Critical: Strict ≤1.0% Lead Specification Non-Negotiable
  • Premium Purity Gate Violation
Test Method
  • Xrf Spectrometry
  • Accurate To ±0.1%
Severity

CRITICAL - PREMIUM SPECIFICATION VIOLATION (ABSOLUTE)

Consequence:
  • Full Rejection
  • Material Loses Premium Red Brass Status Completely
  • May Reclassify To Standard Brass
Ferrous contamination
Threshold

Fe >0.5% OR magnetic attraction detected

Action

Full rejection or mandatory magnetic separation

Reason
  • Premium Specification Violated
  • Ferrous Incompatible With High-Copper Brass
Test Method

Magnetic test + XRF

Severity

CRITICAL - CONTAMINATION

Consequence:

Full rejection or complete material segregation

Stainless steel or aluminum major contamination
Threshold

>0.5% stainless OR >0.5% aluminum detected

Action

Full rejection

Reason
  • Non-Ferrous Incompatible Mixing
  • Wrong Material Stream
Test Method

XRF spectrometry + visual inspection

Severity

CRITICAL - CONTAMINATION

Consequence:
  • Full Rejection
  • Material Fundamentally Contaminated
Bronze contamination excessive
Threshold

Sn >0.5%

Action

Full rejection or major reclassification

Reason

Bronze contamination exceeds premium specification

Test Method

XRF spectrometry

Severity

MODERATE-CRITICAL - CONTAMINATION

Consequence:

Full rejection or substantial penalty

Heavy oxidation/corrosion
Threshold

Heavy rust, pitting, or tarnish >10% surface area

Action

Full rejection

Reason
  • Premium Material Standard
  • Heavy Corrosion Compromises Purity And Material Integrity
Test Method

Visual assessment

Severity

CRITICAL - CONDITION VIOLATION

Consequence:
  • Full Rejection
  • Material Quality Compromised
Hazardous materials detected
Threshold
