Quality Standard

This proven method is widely used to decide whether or not to accept or reject a production lot without checking every single item of the lot. Performed on randomly-selected sample items, once the production lot has been completed and packed, this standard is recognized by every industrial company.
Acceptance sampling is not an alternative to process improvement. Instead it should complement improvement efforts by providing incentives. It also serves as a temporary measure for ensuring quality until successful improvements are made.

Focus on Acceptable Quality Levels

Use the ISO 2859 tables (also known as AQL tables) to measure acceptable levels of quality of the Asian products they inspect. These tables are a US standard with equivalents in all national and international standardization organizations (ANSI/ASQC Z1.4, ISO 2859, NF06-022, BS 6001, DIN 40080).
