    Definitions  
 For the purposes of this standard, the definitions given in IEC 60456  and those 
below apply:  
      Check test  – a full or part test in accordance with IEC 60456  to verify the 
performance and energy consumption of an individual brand and model 
registered for energy labeling.

     Tested energy consumption ( Et) – the measured energy consumption of a 
single unit when tested in accordance with IEC 60456 .  (Units: kilowatt -hours.)  
      Projected annual energy consumption (PAEC)  – the estimate of energy used 
by a model or single unit during one year’s use   It assumes a particular  number 
of uses in one year.  (See also Clause 2.3.) (Units: kilowatt -hours/year.)  
      Comparative energy consumption (CEC)  – the nominal energy consumption 
of a model of clothes washing machine.  It is based on the PAEC estimated for 
the model.  (See al so Clause 2.4.)  The CEC appears on the energy label.  
(Units:  kilowatt -hours/year.)  
      Energy efficiency rating (EER)  – an indication of the claimed energy 
efficiency of a model.  A higher EER indicates a higher energy efficiency.  It is 
derived from the CED.  (See also Clause 2.6.)  The EER appears as a 
continuous red band on the energy label.  (Dimensionless.)  
      Star rating  – the number of stars displayed on the energy label.  It is 
calculated by rounding the EER down to the nearest whole number .  (See also 
Clause 2.7.)  (Dimensionless.)  
      Family of models  – a range of models of the one brand, registered under one 
application, where each of the models on the application has the same relevant 
physical characteristics, comparative energy consum ption, energy efficiency 
rating and performance characteristics   The term ‘model’ is synonymous with 
‘family of models’  
      Variant – a product variant is an alternative version of a product or family of 
products that has the same specifications and th e same model number or other 
form of designation as another registered version of the product except that it 
has a different average PAEC ( PAEC av).  (See also Clause 2.4.2.)  
    MEASURED QUANTITIES  Quantities used in conjunction with this 
standard shall b e measured in accordance with the standard mentioned in 1.2.1.  
 
   MEPS AND CALCULATIONS FOR THE ENERGY LABEL  
    GENERAL   This Section sets out the equations and procedures for calculating 
values of the CEC, EER and the star rating, which appear on an ene rgy label 
and in the application for registration of an appliance for energy labeling.  
 The process consists of measuring the tested energy consumption ( Et) of each 
unit tested, then calculating the projected annual energy consumption (PAEC) 
of the unit.  The values of PAEC for the units tested for registration are used to 
calculate the comparative energy consumption (CEC) for the model.  The CEC, QATAR STANDARD  QS SASO 2692/201   
 
 7 the spin performance and the rated capacity are then used to calculate the 
energy efficiency rating (EER) and t he star rating.  
 Note:  For a complete example of calculations carried out on a typical set of test 
results, refer to Appendix A.  QATAR STANDARD  QS SASO 2692/201   
 
 8     Number of tests and processing of data  
      Number of units required  For the purpose of determining the CEC of a 
model f or registration, three separate units of the nominated model shall be 
tested for energy consumption in accordance with the standard mentioned in 
        At the supplier’s discretion, more than three units may be tested  
      Number of tests per unit   Each  unit shall be subjected to at least one test run 
to obtain a valid value for each of Et and WEI for that unit.  This determination 
shall be documented in a test report  containing the test results.  (Refer to 
Appendices D, E and L of the standard mentione d in 1.2.1.  
      Results from multiple test runs   Where more than one test run is performed 
on a unit, the value of Et and WEI shall be recorded for each run.  For 
subsequent calculations, the values of Et and WEI shall be averaged and treated 
as the resu lt for that unit.  
      Results from more than one unit    After testing three or more separate units 
in accordance with Clause 2.2.1, the separate values of PAEC and WEI shall be 
averaged and referred to as PAEC av and WEI av respectively.  These values shal l 
not be rounded.  
    Projected Annual Energy Consumption (PAEC)   The PAEC of a single 
clothes washing machine shall be given by the following equation:  
    PAEC   =  Et  x  365 (kWh/y)   
 where:  
Et  =  tested energy consumption expressed in kilowatt -hours a s per the 
standard mentioned in 1.2.1, rounded to the nearest 0.001 kWh, 
when tested under the following conditions:  
(a) On the program nominated by the manufacturer in accordance 
with Clause 5.4 of the standard mentioned in 1.2.1 except that, 
if that prog ram results in a test wash water temperature of less 
than 35oC, alternative settings as necessary shall be used to 
achieve a maximum warm wash temperature (i.e. minimum 
  oC). 
(b) At the rated load capacity of the clothes washer for a cotton 
load.  
 The val ue of PAEC yielded by this calculation shall not be rounded.  
    Comparative Energy Consumption (CEC)  
      General   The CEC for a model is the average of the PAEC values (i.e. 
PAEC av) for the three (or more) units which are tested for its registration 
application (refer to Clause 2.2).  The CEC shall be rounded to the nearest 
whole kilowatt -hour/year.  QATAR STANDARD  QS SASO 2692/201   
 
 9       Variant   Where there are a number of variants of a single model with different 
values of PAEC av, each variant may be registered and an applicant for 
registration may, with the written approval of the registering authority, use the 
highest of these values of PAEC av as the CEC on the labels of any of the 
registered variants of that model.  
    Energy Equivalent of Residual Moisture ( Em)  The energy equival ent of 
moisture remaining in the clothes at the end of the program shall be calculated 
as follows:  
    Em  =  
08.1x x21.0 RLC WEIav  
 where:  
         an empirical factor used to account for energy used in clothes 
dryers  
WEI av = the average water extractio n index determined from the standard 
mentioned in 1.2.1 for the three or more machines tested for 
energy labeling  
RLC    = the rated load capacity claimed by the manufacturer for a 
normally soiled cotton load  
          the nominal moisture content of a cot ton load.  
    Energy Efficiency Rating (EER)   The EER shall be calculated by the 
following equation and rounded to the nearest 0.1:  
    EER  =  6.9 –

APPENDIX A  
EXAMPLE OF ENERGY EFFICIENCY CALCULATIONS  
(informative)  
 
This Appendix sets out a typical set of test results.  It demonstrates the application of the 
appropriate procedures required to calculate the tested energy perfor mance for each unit 
and checks for compliance with the standard mentioned in 1.2.1.  The CEC, EER and star 
rating are also calculated.  
Example  
This example sets out the energy label calculations required for a hypothetical clothes 
washer registration.  
A 6. 5 kg load capacity clothes washer has been tested in order to prepare an energy 
labeling application.  The model has connections for both hot and cold water, so the 
machine has been tested with dual water connection.  Test data for the model are as 
follows : 
 
Unit  
Soil 
removal   
Standard 
deviation   
Soil removal  
–2 x SD  Water 
extraction 
index  Severity of 
washing 
index  
                                 
                                 
                                 
 
The soil removal is to be assessed aga inst the performance criteria set out in Clause 3.2.  
The soil removal for each unit is greater than 80% and the soil removal minus twice the 
standard deviation for each unit is greater than 72% so the model meets this requirement.  
The water extraction ind ex for each of the units is to be assessed against the performance 
criteria set out in Clause 3.3.  The water extraction index is less than 1.1 for each unit so 
the model meets this requirement.  
The severity of washing index for each of the units is to be assessed against the 
performance criteria set out in Clause 3.4.  The severity of washing is less than 0.3 for each 
unit so the model meets this requirement.  QATAR STANDARD  QS SASO 2692/201   
 
 15 The PAEC for each unit is determined using Equation 2(1).  (PAEC is the tested energy 
consumption Et x 365.)  The results of these calculations are summarized as follows:  QATAR STANDARD  QS SASO 2692/201

Average                  
 
Note that the values for PA EC are not rounded.  The CEC is determined from the average 
of the 3 PAEC values when rounded to the nearest whole kilowatt -hour/year.  In this case 
the CEC is 700 kWh/year.  
To determine the energy equivalent of residual moisture ( Em).  It is first necessa ry to 
calculate the average water extraction index from the data for the three test units.  This is 
0.845 for these units.  
The calculation of Em is given in Equation 2(2), as follows:  
  Em  =  0.21  x  WEI av  x  
08.1RLC  
         =  0.21  x 0.845  x  
08.15.6  
                     
The energy efficiency rating is determined using Equation 2(3), i.e.  
   EER  =  6.9 –
