1. Lot Information & Smart Controls
Enter received quantity in kilograms. Tons and required samples calculate automatically.
Section Section Weight (Kg) Agreed DRC %
For Cup Lump split lots under the same lot number, enter each section weight and agreed DRC. Final agreed DRC calculates as weighted average.
2. Sampling Details

Final Decision
ACCEPTAll receiving checks accepted and contamination within limit.
CONDITIONALUse for medium/high contamination, excessive moisture, visual issue or tank release issue.
REJECTUse for foreign material, abnormal smell, >8% contamination or failed visual release.
4. Water Tank Monitoring, Identification & Release
Tank Tank Qty (Kg) Soaking Start Earliest Release Soaking Status Water Level Water Cleanliness Visual Cleanliness Action
If one Cup Lump lot is split into two or more soaking tanks, enter each tank separately. All active tanks must complete soaking and pass water/visual checks before Production Supervisor release.
4. Production Release
For Cup Lump, supervisor release before the minimum soaking date is blocked unless Operations Manager Special Approval is entered. Other materials can be released after receiving inspection approval.
5. Final Approval
Fill blue fields only. Contamination %, summary, soaking recommendation and final decision update automatically.

Supplier Details
One supplier can be registered for multiple materials. Hold Ctrl and click to select more than one material. Banned suppliers remain in the register for traceability, but they are hidden from the inspection supplier dropdown.

Quick Guide
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.
