AS NZS 2007.2 pdf download – Performance of household electrical appliances—Dishwashers Part 2: Energy efficiency labelling requirements
This Section sets out the test requirements, equations and procedures for calculating values of the CEC, and the star rating, which appear on an energy efficiency label. The process consists of measuring the tested energy consumption (E t ) and standby power of each unit tested, then calculating the projected annual energy consumption (PAEC) of the unit. The values of PAEC for the units tested are used to calculate the comparative energy consumption (CEC) for the model. The CEC and the rated capacity are then used to calculate the star rating index (SRI) and the star rating. CEC, SRI and star rating are determined using the primary water connection mode for the dishwasher (generally single cold connection).
NOTE: For a complete example of calculations carried out on a typical set of test results, refer to Appendix A. Where the manufacturer allows or recommends any water connection mode in addition to the primary water connection mode, this shall be the supplementary water connection mode (See Clause 1.5.13.) In this case it is necessary to also test the dishwasher in this mode to determine the supplementary energy consumption. It is not necessary to determine performance, SRI or star rating for the supplementary water connection mode, however a soiled load shall be used for this test. Where no alternative water connection mode is allowed in addition to the primary water connection mode, supplementary energy consumption shall not be included on the energy label. (See also Clause 5.4.)
2.2 TEST REQUIREMENTS AND PROCESSING OF DATA
2.2.1 Program for energy efficiency labelling The supplier shall nominate the program for energy efficiency labelling. This shall be the program recommended in the product literature i.e. operating manual or user instructions, to wash a normally soiled load at rated capacity.
This program shall meet the performance requirements of Section 3. If there is a program named ‘Normal’ in the product literature and/or marked on the dishwasher, or one that implies normal such as ‘Universal’ or ‘Regular’, then that program shall be the one nominated as the program for washing a normally soiled load. If there is more than one program recommended to wash a normally soiled load at rated capacity e.g. ‘Normal’, ‘Normal eco’ and/or ‘Normal plus’, then the washing index performance criteria of Section 3 shall be met by each of these programs.
2.2.2 Number of units required For the purpose of determining the CEC of a model for labelling, three separate units of the nominated model shall be tested for energy consumption and standby power in accordance with Section 2 of AS/NZS 2007.1:2005. At the supplier’s discretion, more than three units may be tested.
2.2.3 Number of tests per unit Each unit shall be subjected to at least one valid test run to obtain values of E t and standby power for that unit. This determination shall be documented in a test report. (Refer Appendices D and K of AS/NZS 2007.1:2005.)
2.2.4 Multiple test runs Where more than one test run is performed on a unit, the value of E t shall be recorded for each run. For subsequent calculations, the values of E t shall be averaged and treated as the result for that unit.
2.2.5 Results After testing three or more separate units in accordance with Clause 2.2.2, the separate values of PAEC shall be averaged and referred to as PAEC av
2.3 PROJECTED ANNUAL ENERGY CONSUMPTION (PAEC)
The PAEC of a single dishwasher shall be given by the following equation:
when tested under the following conditions:
(a) On the program for energy efficiency labelling.
(b) With a soiled load in accordance with AS/NZS 2007.1:2005.
(c) At the claimed rated capacity of the dishwasher in accordance with AS/NZS 2007.1:2005.
