Paragraph 1

The energy efficiency class of a dishwasher shall be determined as follows–

• A reference consumption C_R shall be calculated as follows:

• CR = 1.35 + 0.025 × S	when S ≥ 10
  CR = 0.45 + 0.09 × S	when S ≤ 9

• where S is the capacity of the dishwasher in standard place settings (Schedule 1 paragraph 1 note VIII).

• An energy efficiency index E₁ is then set as

• $${\mathrm{E}}_1=\genfrac{}{}{0.1ex}{}{\mathrm{C}}{{\mathrm{C}}_{\mathrm{R}}}$$

  where

  • C is the energy consumption of the dishwasher (Schedule 1 paragraph 1 note V).

• The energy efficiency class is then determined in accordance with Table 1:

• TABLE 1

  Energy efficiency class	Energy efficiency index E1
  A	E1 < 0.64
  B	0.64 ≤ E1< 0.76
  C	0.76 ≤ E1< 0.88
  D	0.88 ≤ E1< 1.00
  E	1.00 ≤ E1< 1.12
  F	1.12 ≤ E1< 1.24
  G	E1 ≥ 1.24
