Glossary:

Inspection Sampling Standard: ISO 2859
Inspection Type: Final Random Inspection (FRI)

Sampling Procedures: Samples are taken at random according to the international standard ISO 2859 by inspectors. The sample quantity represents the number of samples to be taken from a product lot. The acceptance standard represents the agreed Acceptable Quality Level (AQL), or the maximum acceptable number of major and minor defects.
AQL 0: Critical defects (0 defects allowed)

AQL 2.5: Major defects (check sampling standard below)
AQL 4.0: Minor defects (check sampling standard below)

Critical Defect: A defect likely to result in a hazardous or unsafe condition for an individual using the product or fails to meet mandatory regulations.

Major Defect: A defect that is likely to result in failure, reduce the usability and salability and can easily be detected by the customer.

Minor Defect: A defect that does not reduce the usability of the product, can be noticed only after careful examination, and may reduce the salability. It is a workmanship defect beyond the defined quality standard.
