Verification tolerances
8.
(1)
The verification tolerances set out in Table 30 must be used only by the market surveillance authority and only for the purposes of this Schedule.
(2)
The manufacturer, authorised representative or importer of a product must not use the verification tolerances—
(a)
as allowed tolerances to establish the declared values;
(b)
in order to interpret the declared values with a view to achieving compliance; or
(c)
to communicate better performance.
(3)
Where three additional units are tested in accordance with paragraph 5, the determined value for the purposes of Table 30 means the arithmetic mean of the values determined for those three additional units.
Parameters | Verification tolerances |
|---|---|
Total losses (1-η) for motors with a rated output equal to or above 0.12 kW and equal to or below 150 kW | The determined value must not exceed the value (1-η) calculated based on the declared η by more than 15 per cent. |
Total losses (1-η) for motors with a rated output of above 150 kW and equal to or below 1,000 kW | The determined value must not exceed the value (1-η) calculated based on the declared η by more than 10 per cent. |
Total losses for VSDs | The determined value must not exceed the declared value by more than 10 per cent. |
