The defined number of random samples to be tested (200 in the case above) would be taken from the lot, registered in the LIMS, and processed through the analytical testing workflow. Once all the tests have been completed, checked, and approved, a specific AQL inspection screen is used to grade the results.
The AQL inspection screen defines:
- Lot size (Production Units) – 5
- AQL Inspection Level – I
- Acceptable Quality Limit % – 0.25%
The inspection may be carried out against individual tests # (i.e., viscosity of paint), or against all tests assigned to the samples (viscosity, color, lead content, etc.).
