Acceptable Quality Limit (AQL) inspection, also known as sampling inspection, is a widely used quality control method in China and many other manufacturing regions around the world. AQL inspection is a systematic and statistically based approach to assessing the quality of a batch of products or components. It is commonly employed by businesses and importers to determine whether a particular shipment meets predefined quality standards and requirements. The choice of AQL levels (e.g., AQL 1.0, AQL 2.5) and the sampling plan parameters (e.g., sample size, inspection level) depend on the specific quality requirements and risk tolerance of the products being inspected. Lower AQL levels and larger sample sizes provide more stringent quality control but may increase inspection costs and time.

What will we do with AQL Inspection?

Arrow

Sampling Plan

Follow the established sampling plan to select a representative sample from the batch for inspection. Understand the sampling procedures and the relationship between sample size and confidence levels.
Arrow

Quality Inspection
