The food waste disposer shall
32、be run through 10 completeoperational cycles, of a 30 s duration, with a hard test load (3.102). 6.1.4 Notapplicable.6.2 Supply of electric energy and of water or gas 6.2.1 Replacement: The supply voltage is measured at the plug of a non-detachable cable or cord, at theappliance inlet if a detachabl
33、e cord is provided or no cable is provided, but in no case at theentrance of extensions cables or cords.6.2.2 Notapplicable6.2.3 Notapplicable6.2.4 Replacement: The temperature of the supply water shall be between 4 C and 27 C. The flow rate of the water supply shall be 6 0,3 L/min. The water faucet
34、 shall be positionedin such a way that the water flows down the side of the sink into the drain, creating negligiblewater splash noise.6.4 Loading and operating of appliances during tests6.4.2 Replacement: The test load shall be at room temperature when the test program starts. The appliance under t
35、est shall be at room temperature when the test program starts. The appliance shall be operated according to 3.101 using each of the test loads as describedin 3.102 and 3.103. An operator shall be present to place the test load in the grind chamberand to start and stop the operational cycle of the di
36、sposer. The operators position shall bechosen to minimize the influence upon the acoustic measurement and shall be consistent forall tests.DD IEC/PAS 60704-2-15:2008PAS 60704-2-15 IEC:2008(E) 9 A 10 s measurement shall be taken that encompasses the start of the operational cycle.Upon completion of t
37、he measurements, the remaining material in the grind chamber is to beremoved and the disposer flushed with water to ensure no material remains. An auditorycheck shall be made of the unit running without any water or load to ensure that no materialremains in the grind chamber. Ensure that no test loa

The minimum area of thispart of the wall should be determined by the projection of the appliance, extended by at least0,5 m upwards and
41、 to both sides. The minimum distance between any surface of theappliance (cabinet, counter, or test enclosure) and the nearest corner of the room shallbe 1 m.When measurements are made in a free-field environment, a vertical-reflecting plane(supported by the horizontal reflecting plane) shall be pro
42、vided. The minimum size of thisvertical plane shall be at least equal to the size of the projection of the measurement surface.For both types of test environments, the requirements given below shall be followed. the acoustic absorption coefficient of the vertical reflecting plane shall be less than
