On Site Tests
On site tests can be performed during a product inspection, for example during production inspection or pre-shipment inspections. these tests merely compliment the results of the laboratory test: they are performed on a bigger sample size (based on AQL special inspection levels S1 or S2 most of the time). and their great advantage is the low cost and easy logistics.
