Meaning
Quality control methodology sorting manufactured output into binary categories based on predefined acceptance criteria rather than recording exact physical dimensions. Attribute inspection operates inside the purchase order specification and functions as the primary gatekeeper before shipment release occurs. Commercial agreements reference this protocol within the quality schedule to establish sampling plans, acceptable quality limits, and defect classifications.
The procedure stops applying once goods leave the factory floor, because transit damage falls under different liability clauses.
Defect Classification
Production auditors divide nonconformities into distinct severity tiers inside the inspection report, allocating major flaws and minor flaws to separate categories. Commercial friction arises when buyers and suppliers disagree on the boundary separating a cosmetic blemish from a functional failure. Factories deploy sorting protocols during mass manufacturing runs to capture workmanship errors before final packing lists finalize.
Financial Exposure
Rejected batches trigger rework costs, production delays, and additional third party auditor fees under standard supply contract terms. Buyers absorb shipment holding charges when attribute inspection delays container loading schedules at the port of origin. Dispute resolution clauses protect purchasing margins by tying final payment release directly to passing inspection certificates.
Sampling Standard
Statistical tables dictate sample sizes and acceptance numbers based on lot sizes and agreed quality levels. Operational teams select random units from finished pallets, counting total failures against predetermined thresholds to determine batch disposition. Strict statistical parameters prevent subjective rejections from disrupting vendor relationships during commercial negotiations.
