1. EnterFill only blue cells in the Inspection Form: material type, lot details, received quantity (Kg), agreed DRC sections, actual sample locations, sample weights, contamination weights and remarks.
2. SamplesRequired sample count calculates automatically from received quantity: 1-3 Tons = 3 samples, 4-7 Tons = 5 samples, 8-10 Tons = 8 samples, above 10 Tons = 10 samples.
3. LocationsSuggested locations are provided automatically for lorry unloading: Front, Middle, End, then random points. You can overwrite in Actual Location if needed.
4. ContaminationContamination % per sample = contamination weight / sample weight. The form calculates each sample and the overall average automatically.
5. Final decisionACCEPT, CONDITIONAL or REJECT is generated automatically using contamination grade, colour, appearance, foreign material, smell and soaking/tank release controls.
6. SoakingOnly Cup Lump requires soaking according to this SOP setup. Clean material / Contamination A = minimum 48 hours, Medium contamination / Contamination B = 60 to 72 hours, Heavy contamination = 72 to 96 hours.
7. Tank checksRubber must be fully submerged and water must not be excessively muddy. Any failure holds release until corrected.
8. ReleaseAfter the minimum soaking date, the Production Supervisor may release material to production. Early Cup Lump release is blocked unless Operations Manager Special Approval is recorded.
9. DRC calculationAfter oven output is available, use the DRC Calculation section to calculate actual DRC, variation and monthly Excel summary from lot-wise records.
10. Non-conformingFailed material must be segregated and recorded with action: re-cleaning, extended soaking, downgrading or rejection.
ResponsibilitiesQC Officer conducts inspection and contamination evaluation. Store Keeper records deliveries, lot numbers, unloading and soaking time. Production Supervisor ensures only approved materials enter production.
