Rejection criteria

Rejection criteria refer to the specific standards or conditions used to determine whether a product, application, or sample is acceptable or should be rejected. These criteria are established to ensure quality, safety, or compliance with guidelines. If an item fails to meet one or more of these predefined standards—such as size, quality, or safety features—it is considered unacceptable and rejected. Having clear rejection criteria helps maintain consistency, fairness, and reliability in processes like manufacturing, testing, or evaluation.
