(a)

the result for no-load condition does not exceed the applicable limit value set out in Annex I by more than 0,10 W; and

(b)

the arithmetic average of efficiency at load conditions 1-4 as defined in Annex I does not fall below the applicable limit value for average active efficiency by more than 5 %.

3. If the results referred to in points 2(a) and (b) are not achieved, three additional units of the same model shall be tested. U.K.

4. After three additional units of the same model have been tested, the model shall be considered to comply with the requirements if: U.K.

(a)

the average of the results for no-load condition does not exceed the applicable limit value set out in Annex I by more than 0,10 W; and

(b)

the average of the arithmetic averages of efficiency at load conditions 1-4 as defined in Annex I does not fall below the applicable limit value for average active efficiency by more than 5 %.

ANNEX III U.K. INDICATIVE BENCHMARKS REFERRED TO IN ARTICLE 6

(a) No-load condition U.K.

The lowest available no-load condition power consumption of external power supplies can be approximated by:

• 0,1 W or less, for P_O ≤ 90 W,

• 0,2 W or less, for 90 W < P_O ≤ 150 W,

• 0,4 W or less, for 150 W < P_O ≤ 180 W,

• 0,5 W or less, for P_O > 180 W.

(b) Average active efficiency U.K.

The best available active average efficiency of external power supplies according to most recent available data (status January 2008) can be approximated by:

• 0,090 · ln (P_O) + 0,680, for 1,0 W ≤ P_O ≤ 10,0 W,

• 0,890, for P_O > 10,0 W.
