Sample Size Code
Meaning ~ Alphanumeric letters mapping production batch sizes to required inspection sample quantities under international attribute sampling standards
Batch Inspection
Meaning
Sampling procedures applied to discrete production lots evaluate conformance against purchase order specifications before final shipment release. A formal batch inspection establishes whether an entire manufacturing run meets accepted quality limits based on a representative sample rather than full unit testing. The procedure governs physical characteristics and functional parameters for the specific lot under review.
It stops at the boundary of the submitted lot and does not guarantee the compliance of subsequent production units.
Operational Trigger
Factory quality control departments initiate this examination when a supplier presents a formal notice of readiness. A field surveyor draws units according to pre-selected sampling tables, evaluating dimensions and surface finish. Rejection halts export packing.
Financial Liability
Failed evaluations transfer immediate holding fees and re-examination expenses to the seller under standard purchase agreements. Initial testing costs reside with the buyer during primary sweeps, but secondary passes triggered by non-conformance become line-item deductions. Buyers execute debit notes directly against open letters of credit when delivery delays activate.
Data Discrepancy
Disagreements arise when factory floor metrics conflict with port destination test results due to transit degradation. Damp container environments alter physical dimensions. Clear baseline logging at the factory gate prevents unearned penalty claims.
Sample Size Code Letter
Meaning ~ Alphanumeric identifier from standard tables that dictates the minimum number of units required for inspection based on the total lot size and level selected.
