2.CLEANING PERFORMANCE INDEX
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
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.
