# Commission Regulation (EU) 2019/2022 of 1 October 2019 laying down ecodesign requirements for household dishwashers pursuant to Directive 2009/125/EC of the European Parliament and of the Council amending Commission Regulation (EC) No 1275/2008 and repealing Commission Regulation (EU) No 1016/2010 (Text with EEA relevance), Division 2: CLEANING PERFORMANCE INDEX

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

For the calculation of the cleaning performance index (IC) of a household dishwasher model, the cleaning performance of the eco programme is compared to the cleaning performance of a reference dishwasher.
The IC is calculated as follows and rounded to two decimal places:
IC = exp (ln IC)
and
ln IC=1/n×∑i=1nlnCT,i/CR,i
where:
CT,i is the cleaning performance of the eco programme of the household dishwasher under test for one test run (i), rounded to two decimal places;
CR,i is the cleaning performance of the reference dishwasher for one test run (i), rounded to two decimal places;
n is the number of test runs.
