Where to Conduct On-Site Tests During Coffee Maker Inspections
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 the AQL Table). And their great advantage is the low cost and easy logistics.

- When pressed, the Program button must work as intended.
- Detailed function claimed on gift box and instruction manual
3. Fatigue Test
20 times for each button, plug, and switch
4. Rub Check

- 12inch (27.7kg~45.3kg)
- 8inch (45.3kg~68kg) on the cement floor.
9. Hi-pot test:
3S, setting. 3500V for class II; 1500V for class I
10. Earth continuity check:
25A for 1 second, ≤ 0.1ohm
11. Input Power check:
Heating appliance:
- within +5% and -10% of﹥200W,
- within ±10% of 25W~200W,
- within +20% of ≤25W;
12. Application test:
Use coffee for real function check
13. Internal check :
Inspector will open the unit, visual check the workmanship, and no damage to the component. Check whether the components conform with CDF(Construction Da
