IEC 60335-2-11 Washing Machine Door Performance Tester With Touch Scteen

Standard description:

20.101 Appliances shall have means to prevent opening of the door during operation or an interlock which disconnects the motor before the door opening exceeds 75 mm. It shall not be possible to start the motor while the door opening exceeds 75 mm. For appliances with a door opening having a dimension exceeding 300 mm and a drum having a volume exceeding 100 dm³ , starting of the motor shall not be possible until a separate means which controls the movement of the drum is operated manually. However, for appliances loaded from the front, the dimension are reduced to 25 cm for the door opening and 75 dm³ for the drum volume.              Electrical Appliance Tester

Interlocks shall be constructed so that unexpected operation of the appliance is unlikely to occur while the door is open.

Compliance is checked by inspection, by measurement and by manual test with the appliance supplied at rated voltage and under normal operation .            Electrical Appliance Tester

If means to prevent the door opening incorporates a coil or similar component to lock the door in the closed position, the component is energized and de-energized 6 000 times, six times a minute or at the rate imposed by the construction of the appliance if this is lower.

The locking means and its components shall be fit for further use.

NOTE 1 The door is opened and closed during the test if this is necessary for the mechanical operation of the interlock.

NOTE 2 Interlocks which can be released by means of the test finger shown in figure 1 are considered likely cause unexpected operation of the appliance.
