2. CALCULATION OF THE DRYING EFFICIENCY INDEX

For the calculation of the Drying Efficiency Index (I_D ) of a household dishwasher model, the drying efficiency of the household dishwasher is compared to the drying efficiency of a reference dishwasher, where the reference dishwasher shall have the characteristics indicated in the generally recognised state-of-the-art measurement methods, including methods set out in documents, the reference numbers of which have been published for that purpose in the Official Journal of the European Union.

(a)

The Drying Efficiency Index (I_D ) is calculated as follows and rounded to two decimal places:

I_D = exp(lnI_D )

where:

D_T,i

=

drying efficiency of the household dishwasher under test for one test cycle (i);

D_R,i

=

drying efficiency of the reference dishwasher for one test cycle (i);

n

=

number of test cycles, n ≥ 5.

(b)

The drying efficiency (D) is the average of the wet score of each load item after completion of a standard cleaning cycle. The wet score is calculated as shown in Table 1:

Table 1

Number of water traces (WT) or wet streak (WS)	Total wet area (Aw) in mm2	Wet score
WT = 0 and WS = 0	Not applicable	2 (most efficient)
1 < WT ≤ 2 or WS = 1	Aw < 50	1
2 < WT or WS = 2 or WS = 1 and WT = 1	Aw > 50	0 (least efficient)
