19.4 Replacement:
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.
19.9 Addition:
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 lithe protective device senses the winding temperature directly.
19.13 Addition:
The textile material shall not ignite and shall show no charring or glowing.
NOTE 101 Light-brown colouring of the textile material or slight emission of smoke is ignored.
19.101 The appliance is operated under the conditions specified in Clause 11 but with dry textile material and the drum belt removed. The duration of the test is 90 mm or for the maximum period allowed by a timer.
If air circulation is likely to be prevented due to a fault condition, the test is repeated but with the drum belt in position and with the air circulation stopped. Care shall to be taken to ensure that the textile material is tumbling properly by reducing the load if necessary.
If both these conditions are likely to occur simultaneously, the tests are combined.
19.102 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.
19.103 There shall be no risk of fire due to textile material coming into contact with a lamp cover.
Compliance is checked by the following test.
Ten layers of cheesecloth are placed over the lamp cover. The appliance is supplied at rated voltage with the door open until steady conditions are established. The temperature rise of the cover shall not exceed 150 K.AS NZS 60335.2.11 pdf download.
