Appliances that are suspended in normal use are placed on the floor of the test corner in the most unfavourable position. This position may be obtained for example by the use of distance knobs, a bow, hoop, shielding grid or fender so constructed that the appliance capsizes when it is laid on its base or the floor.
The appliances are operated as follows under the conditions given in Clause 11:
– in appliances with thermostats but without built-in fans, this test shall be carried out with an input as obtained under the test conditions specified in Clause 11;
– in appliances without thermostats but with builtin fans, the latter shall be stalled according to 19.7;
– appliances with thermostats and built-in fans are tested at first with short-circuited thermostats and running fans and then with stalled fans according to 19.7 and operating thermostats.
The heat-radiating appliance is fixed by its means of suspension in accordance with the manufacturer’s instructions. A load is applied to the body of the appliance so that the load on the means of suspension is five times the mass of the appliance or 20 kg, whichever is larger.The load is applied gradually and maintained for 1 min, after which it is removed.
One of the additional samples of the means of suspension is subjected to the salt mist test described in IEC 60068-2-11, test Ka, which is made with the means of suspension mounted as in normal use; it is kept in the test chamber for 7 days (168 h).
After the test, the means of suspension shall show no sign of deterioration that could affect compliance with this standard, and its coating, if any, shall not have loosened from the metal surface and shall not have been pieced.
The other additional sample of the means of suspension, if of non-metallic material, shall be subjected to the glow-wire test of IEC 60695-2-11 which is carried out at 850 °C.AS NZS 60335.2.71 pdf free download.
