The appliance is operated under the conditions specified in Clause 11 but with dry textile material. Controls that limit the temperature during the test of Clause 11 and all self-resetting thermal cut-outs that protect the heating elements are short-circuited simultaneously. The test is terminated at the end of the maximum period allowed by a timer.
For condensation-type tumble dryers, the test is repeated, but with 75 % of the air outlet of the condenser blocked. The test is then carried out again with the air outlet fully blocked.
The running overload test is carried out on appliances that have overload protective devices incorporating electronic circuits to protect the windings of the drum motor. However the test is ;not carried out if the protective device senses the winding temperature directly.
Appliances that permit test probe C of IEC 61032 to gain access to spaces containing live parts located below holes in the drum are tested for short circuit conditions.
The short circuit is applied at the most unfavourable place between live parts and between live parts and other metal parts, if such a short circuit can be made by a pin having a diameter of approximately 1 mm and any length up to 50 mm. The appliance is operated as specified in Clause 11 but with dry textile material.
It shall not be possible to open the door while the appliance is operating unless an interlock is provided that 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.
Compliance is checked by inspection, by measurement and by manual test, the appliance being supplied at rated voltage and operating under normal operation.
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.AS NZS 60335.2.11 pdf free download.
