6 Operation and location of appliances under test This clause of Part 1 is applicable except as follows:
6.1 Equipping and pre-conditioning of appliances
6.1.3
Replacement:
Prior to commencing measurements, the inner surfaces of the appliance and filters shall be clean and the salt container, if included, shall be filled with water. Then the appliance shall be operated for at least two programme cycles as specified in 3.104, with or without load.
6.1.4 Not applicable.
6.2 Supply of electric energy and of water or gas
6.2.2 Not applicable.
6.2.3 Not applicable
6.2.4
Replacement:
Dishwashers designed for either cold or hot water supply shall be supplied with cold water.
The water hardness may be neglected.
For noise measurements the static water pressure during filling shall be (240 ± 50) kPa. if not contradictory to the manufacturer’s instructions. The temperature of cold water shall be (15 ± 5) °C and the temperature of hot water shall be (55 ± 5) °C.
NOTE When, in some countries, the water supply pressureltemperature differs from the water supply pressure! temperature of the country concerned, measurements carried out at rated pressure/temperature may be misleading for the consumer In this case. additional measurements may be necessary. If the test pressure/temperature differs from the rated pressure/temperature, this should be reported.
Appliances with an unremovable worktop and appliances specified by the manufacturer for free-standing use only shall be measured free-standing. All other appliances shall be placed in a test enclosure, as described in figure 101, and the worktop — if any — shall be removed.
The front edge of the housing of the dishwashers designed to be built in (except door) shall be 20 mm to 25 mm behind the front edge of the test enclosure. If required by the manufacturer’s instructions, the enclosure shall be provided with ventilation openings accordingly.
In the rear left or right corner of the test enclosure, a cut-out at minimum size should be provided and shut by sealing means to avoid any noise leakage. This cut-out is provided to enable water and electricity supply as well as drainage. Care should be taken that no structure-borne noise is transmitted to the test enclosure.
If an appliance is provided with spacers, strips or other special means of solid or resilient material for closing the gap(s) between the contours of the appliance and the cabinet or enclosure, these means shall be used accordingly. If such means are not provided, the gap(s) are left open.
The test enclosure with the appliance is placed according to 6.53.
Appliances to be integrated shall be installed under the same conditions as built-in appliances. In addition, the door of the dishwashers shall be equipped, in accordance with the manufacturers instructions, with a board of the maximum size allowed by the manufacturer and of the same material and thickness as the test enclosure, see figure 101.
Moreover the test enclosure shall be provided, in accordance with the manufacturers instructions, at its lower front side with a skirting board of the maximum height which corresponds with the size of the board on the door of the appliance and of the same material and thickness as the test enclosure, see figure 101. If no instructions are given by the manufacturer, a skirting board as described above shall be pressed against the skirting board of the appliance.
