Lot Acceptance
Meaning ~ Lot acceptance is the formal process of verifying that a specific production run meets the contracted quality thresholds before ownership or payment transfers
Master Sample
Meaning
Physical specimen approved by both buyer and supplier to serve as the definitive benchmark for appearance and tolerance. A master sample provides a tactile reference that technical drawings cannot fully capture.
Golden Unit
Creation of the reference occurs during the final stages of product development to lock in the aesthetic expectations. This master sample represents the ideal version of the product that the factory is capable of making consistently. It is signed and dated by both parties to prevent future disagreements.
Without this physical proof, inspectors rely on memory or screen displays.
Preservation Protocol
Storage in a controlled environment prevents the reference from fading or warping over time. A master sample kept in direct sunlight will lose its color accuracy and become useless for comparison. Protective cases and limited handling ensure the specimen remains in its original state.
Duplicate sets are often kept at both the source and the destination.
Dispute Resolution
Comparison between the produced goods and the approved specimen settles arguments about whether a batch meets the contract. If the finish on the line does not match the master sample, the buyer has the right to reject the shipment. This direct physical check bypasses the ambiguity of written descriptions.
It is the most effective tool for maintaining consistency across multiple production locations.
