# Commission Delegated Regulation (EU) 2019/2017 of 11 March 2019 supplementing Regulation (EU) 2017/1369 of the European Parliament and of the Council with regard to energy labelling of household dishwashers and repealing Commission Delegated Regulation (EU) No 1059/2010 (Text with EEA relevance), Division 3: DRYING PERFORMANCE INDEX

Extent: E+W+S+N.I.

For the calculation of the drying performance index (ID) of a household dishwasher model, the drying performance of the eco programme is compared to the drying performance of the reference dishwasher.
The ID is calculated as follows and rounded to two decimal places:
ID = exp (ln ID)
and
In ID=1/n×∑i=1nlnID,i
where:
ID,i is the drying performance index of the eco programme of the household dishwasher under test for one test run (i);
n is the number of combined cleaning and drying test runs.
The ID,i is calculated as follows and rounded to two decimal places:
ln ID,i= ln (DT,i/DR,t)
where:
DT,i is the average drying performance score of the eco programme of the household dishwasher under test for one test run (i), rounded to two decimal places;
DR,t is the target drying score of the reference dishwasher, rounded to two decimal places.
