Final Random Inspection (FRI)

Final Random Inspection (FRI) is a final-stage inspection conducted after 100% of the goods are produced and at least 80% are packed. This inspection uses random sampling to evaluate the overall quality of the production batch.

Standards:

• AQL Standards: FRI is conducted based on Acceptable Quality Level (AQL) standards, which determine the sample size and allowable defect ratios.
• Product Technical Specifications and Standards: FRI typically follows product technical specifications, contractual requirements and industry standards.

Inspection Content:

• Perform random sampling inspection on a large batch of products.
• Check whether the products meet the quality standards specified in the contract.
• Verify whether qualified products meet the standards for factory release.

Process:

1. Random Sampling: Randomly select a certain number of samples from the completed goods for inspection.
2. Quality Validation: Check the appearance, functionality and quality of the sampled products against the standards.
3. Report Generation: Generate a final inspection report based on the results to confirm product compliance.
4. Shipping Decision: Decide whether to ship the goods based on the inspection results. If issues are found, rework or reproduction may be required.
