IEC60335-2-11 Clause 20.101
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 75mm .it shall not be possible to start the motor while the door opening exceeds 75mm ,for appliance with a door opening having a dimension exceeding 30cm and a drum having a volume exceeding 100dm³,starting of the motor shall not be possible until a separate means which controls the movemend of the drum is operated manually .however ,for appliances loaded from the front ,the dimension are reduced to 25cm for the door opening and 75dm³ for the drum volume .
Interlock shall be constructed so that unexpected operation of the appliances 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 .
It means to prevent the door opening incorporates a coil or similar component to lock the door in the closed position ,the competent is energized and de-energized 6000times ,six times a minute or at the rate imposed by the construction of the appliance if this is lower .
The locking means and its competent shall be fit for further use .
