How to Perform On Site Tests During a Coffee Maker Inspection?

On-Site Tests

On-site tests can be performed during a coffee maker inspection, for example, during production inspection or pre-shipment inspections. These tests merely complement 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, Learn more from AQL Table). And their great advantage is the low cost and easy logistics.
