The model conforms to paragraph 7 of Schedule 19 (availability of off, standby and networked standby modes) where—
a
it provides—
i
off mode;
ii
standby mode; or
iii
another mode which does not exceed the applicable power demand requirements respectively for standby or networked standby mode;
when the electronic display is connected to the power source;
b
the activation of the network availability requires the end-user’s intervention;
c
the network availability can be disabled by the end-user; and
d
it complies with the requirements for standby mode when networked standby mode is not enabled.
Verification procedure for requirements of paragraph 8 of Schedule 1911
1
The model conforms to paragraph 8 of Schedule 19 (automatic power-down in televisions) where—
a
within 4 hours in on mode following the last user interaction, the television automatically powers down from on mode to—
i
standby mode;
ii
off mode;
iii
networked standby mode, if enabled; or
iv
another mode which does not exceed the applicable power demand requirements for standby mode;
b
the power-down function referred to in paragraph (a) is set as default;
c
in on mode, the television shows an alert message before automatically powering down from on mode to the applicable mode;
d
if the television provides a function allowing the user to modify the 4-hour period for automatic mode power-downs referred to in paragraph (a)—
i
a warning message is prompted about a potential increase in energy use; and
ii
a confirmation of the new setting is requested when an extension beyond the 4-hour period or disabling is selected;
e
if the television is equipped with a room presence sensor, the automatic power-down from on mode into any mode referred to in paragraph (a) applies if no presence is detected for no more than 1 hour; and
f
in televisions with various selectable input sources, the power management protocols of the signal source selected is prioritised over the default power management mechanisms referred to in paragraph (a).
2
For the purposes of sub-paragraph (1)(a), the market surveillance authority must use the applicable procedure to measure the power demand after the automatic power-down functionality switches the television into the applicable power mode.
Verification procedure for requirements of paragraph 9 of Schedule 1912
The model conforms to paragraph 9 of Schedule 19 (automatic power-down in displays other than televisions) where—
a
the model is tested for—

in the case of other HFRs, the determined value for any homogenous material does not exceed 0.1 per cent by weight of halogen content. Where the determined value for any homogenous material exceeds 0.1 per cent by weight of halogen content, the model may still be considered compliant where documentary checks or any other appropriate, reproducible methods show that the halogen content is not attributable to flame retardant.
Procedure if requirements are not achieved15
1
If a unit/model complies with the conditions of paragraph 4 except sub-paragraph (d) or (e), or both—
a
where the conditions which are not met include requirements that do not involve measured values, the model and all equivalent models do not conform to these Regulations;
b
where the conditions which are not met relate to requirements that involve measured values, the market surveillance authority must test three additional units of the model to be verified, or three units of equivalent models.
2
A model subject to additional testing under this paragraph is deemed to comply with the relevant condition if the arithmetical mean of the determined values for the three additional units meets the verification tolerances set out in Table 33 below.
3
If a model fails to meet the test set out in sub-paragraph (2), the model and all equivalent models do not conform to these Regulations.
Verification tolerances16
1
The verification tolerances set out in Table 33 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 15, the determined value for the purposes of Table 33 means the arithmetic mean of the values determined for those three additional units.
