36、cording to Clause 9. 5 General conditions for measurements For energy labelling purposes the standard is only used with cold water. 5.1 General The dishwasher manufacturers instructions regarding installation and use of the dishwasher shall be followed, except where there is a conflict, in which cas

37、e this standard shall prevail. Performance tests according to this standard document shall be generally carried out on a new machine, with a reference machine running parallel with the machine(s) under test, i.e., at the same time under the same conditions using soil prepared at the same time from t

38、he same batch. The reference machine shall be in accordance with the description given in Annex E. The reference machine shall always be installed as a free standing machine independent of the type of machine under test. Before commencing measurements, the dishwasher and the reference machine shall

39、be checked to ensure that they are operating properly. All tests shall be started with the appliances at the ambient temperature according to 5.5. 5.1.1 Free standing dishwashers Dishwashers shall be tested as free standing except where they are designated as builtin or integrated (refer to 5.1.2).

40、The dishwasher manufacturers instructions regarding installation and use of the dishwasher shall be followed. 5.1.2 Built in and integrated dishwashers Built-in dishwashers have to be installed in an enclosure. See Annex I, Figure I.1. The front edge of the housing of the dishwasher (except the door

41、) shall be 20 mm to 25 mm behind the front edge of the test enclosure. If required by the manufacturers instructions, the enclosure shall be provided with ventilation openings accordingly.

42、the SABS .EN 50242:2008 - 8 - EN 60436:2008 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 enclosure, these means shall be used accordingly. If such means are not prov

43、ided, the gap(s) shall be left open. Appliances to be integrated shall be installed under the same conditions as built-in appliances. In addition, the door of the dishwasher shall be equipped, in accordance with the manufacturers instruction, with a board of the maximum size allowed by the manufactu

44、rer and of the same material and thickness as the test enclosure; see Annex I. Moreover, for integrated types, 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

45、of the board on the door of the appliance and of the same material and thickness as the test enclosure, see Annex I. If no instructions are given by the manufacturer, a skirting board as described above shall be pressed against the skirting board of the appliance. 5.2 Conditioning of the machine und

46、er test and sequence of test procedures Before conducting the performance tests, the dishwasher shall be operated for three complete cycles using a clean load with reference detergent (specified in 5.7) and without rinse agent. No additional cycles shall be carried out on the machine under test betw

47、een the sequential steps specified in the following procedure. The tests shall be performed in the following order: cleaning performance (Clause 6) then drying performance (Clause 7). The determination of energy, water and cycle/program time (Clause 8) shall be done in conjunction with a cleaning pe

48、rformance test (Clause 6). NOTE 1 The above sequence is necessary for better reproducibility, i.e. to avoid differences in drying performance due to the aging process of the plastic parts in the dishwasher (for example, racks). NOTE 2 Any cycles or operations performed on the appliance during the ma

49、nufacture of the product are ignored. NOTE 3 Noise tests require that the test should be carried out before the rinse aid dispenser is filled for the first time. 5.3 Electricity supply for machines 5.3.1 Electricity supply for test machine 5.3.1.1 Voltage The supply voltage shall be maintained at 230 V + 1 %. The supply voltage measured during the tests shall be recorded. NOTE Also the micro-wave oven shall be operated under the same conditions. 5.3.1.2 Frequency The supply frequency shall be set at the rated frequen
