- EPEC is the eco program energy consumption of the household dishwasher, 
measured in kWh/cycle and rounded to three decimal places.  
- SPEC is the standard program energy  consumption of the household dishwasher.  
 
(b) The SPEC is calculated in kWh/cycle and rounded to three decimal places as follows:  
 
1) for household dishwashers with rated capacity ps ≥ 10 and width > 50 cm:  
SPEC = 0 .025 × ps + 1 .350

to one decimal place.  
- WRF: water reduction factor  (17.5 %) = 0.175   
- BWC:  base water consumption = 2.5 + ps × 1.6  
Where:  
- ps: is the number of place settings.

16 Where:  
- CT,i: is the cleaning performance of the eco program for one test run (i), rounded to 
three decimal places.  
- CR,i: is the cleaning performance of the reference dishwasher for one test run (i), 
rounded to three decimal places.  
- n: is the number of test runs.  
A.6 Drying Performance Index  
The drying performance index ( 𝐼𝐷) is calculated  by using the following formula , rounded to 3 
decimal places : 
𝐼𝐷= exp (ln 𝐼𝐷) Formula (A.6.1)  
And   
In 𝐼𝐷= (1/n) ×  ∑ ln(𝐼𝐷,𝑖)𝑛
𝑖=1  Formula (A.6.2)  
Where:  
 
- ID,i: is the drying performance index of the eco program for one test run (i).  
- n: is the number of combined cleaning and drying test runs.  
- ID,i: is calculated as follows and rounded to three decimal places.  
 
In 𝐼𝐷,𝑖= In × (𝐷𝑇,𝑖 / 𝐷𝑅,𝑡) Formula (A .6.3) 
 
Where:  
 
- DT,i: is the average drying performance score of the eco program for one test run (i), 
rounded to three decimal places.  
- DR,t: is the target drying score of the reference dishwasher, rounded to three decimal 
places.  
A.7 Low Power Mode  
The power consumption of th e off mode (P o), standby mode (P sm) and where applicable delay 
start (P ds) are measured and submitted e xpressed in W rounded to two decimal places.  During 
measurements of the power consumption in low power modes, the following shall be checked 
and recorded:  
- the display or not of information.  
- the activation or not of a network connection.
