Paragraph 3 Cleaning performance index

(1)

The cleaning performance index (“I_C”) is determined as follows.

(2)

For all household dishwasher models, the I_C is calculated by comparing the cleaning performance of the eco programme to the cleaning performance of a reference dishwasher.

(3)

The I_C must be rounded to three decimal places and is calculated as follows—

I_C = exp (ln I_C) and

n I_C = (1/n) × Σⁿ _i=1 ln(C_T,i/C_R,i).

(4)

For the purposes of sub-paragraph (3)—

(a)

C_T,I is the cleaning performance of the eco programme of the household dishwasher under test for one test run (i) , rounded to three decimal places;

(b)

C_R,i is the cleaning performance of the reference dishwasher for one test run (i), rounded to three decimal places;

(c)

n is the number of test runs.
