- Energy efficiency parameters calculated from the above measurements (e.g. the total energy consumption, based on a pre-defined duty cycle);
- The external power supply efficiency;
- The noise levels (the declared A-weighted sound power level) of the computer;
- The minimum number of loading cycles that the batteries can withstand;
- Whether internal batteries can be "accessed and replaced by a nonprofessional user", and whether the related text is present and legible on the external packaging;

Introduction
A preparatory study carried out by the European Commission estimated the cost-efficient improvement
potential in the electricity consumption of computers between 2011 and 2020 at about 93 TWh, which
corresponds to 43 Mt of CO2 emissions, and in 2020 at between 12,5 TWh and 16,3 TWh, which corresponds
to 5,0-6,5 Mt of CO2 emissions. Consequently, computers constitute a product group for which Ecodesign
requirements have been established.
Since much of the energy-savings potential of desktop thin clients, workstations, small-scale servers and
computer servers is linked to the efficiency of their internal power supplies and since the technical
specifications of internal power supplies for these products are similar to those for desktop computers and
integrated desktop computers, the provisions on internal power supply efficiency set up for desktop computers
also apply to desktop thin clients, workstations, small-scale servers and computer servers.
While the focus is put on energy consumption, computer products (and energy-related products in general)
are expected to be designed in such a way to also preserve other resources.
The present European Standard provides a way to determine compliance of computers and computer servers
in scope of Commission Regulation (EU) N° 617/2013 with the applicable requirements through reliable,
accurate and reproducible measurement methods, which take into account the recognized state of the art,
including, where available, existing harmonized standards established in conformity with the applicable
European standardization legislation. It also provides guidance for declarations that are required under the
same Regulation.

for the purpose of the measurement.
4.1.2 Off mode with Wake-On-LAN
For desktop computers, integrated desktop computers and notebook computers with Wake-On-LAN in off
mode functionality enabled as factory default, the measurement shall be repeated after Wake-On-LAN from
off mode has been re-enabled through the operating system or by other means, and the EUT placed back in
off mode.
Measurement shall be performed on desktop computers, integrated desktop computers, and notebook
computers, after they automatically switched to off mode with Wake-On-LAN, as a result of a given period of

Test setup, test conditions, and measurement instrument specifications shall comply with 6.1.
If off mode with Wake-on-LAN is not the low power mode into which the computer automatically switches after
a certain period of inactivity, the computer shall be manually forced into off mode with Wake-on-LAN for the
purpose of the measurement.
4.2 Energy consumption in sleep mode
4.2.1 Sleep mode without Wake-On-LAN
Energy consumption in sleep mode shall be determined in accordance with EN 62623:2013, 5.3.3.

Test setup, test conditions, and measurement instrument specifications shall comply with 6.1.
4.4 Energy consumption in the lowest power mode
For desktop computers, integrated desktop computers and notebook computers where the off mode is the
lowest power state, the energy consumption in the lowest power state is identical to the one determined in
accordance with 4.1.1.
NOTE There is no need to duplicate this measurement if no additional state is provided.
For desktop computers, integrated desktop computers and notebook computers with an additional power
state, where the power demand is lower than in off mode, an additional measurement shall be made in
accordance with EN 62623:2013, 5.3.2, where “off mode” is replaced by that additional state.
4.5 Annual total energy consumption
Annual total energy consumption shall be determined, using a theoretical duty cycle, taking into account the
energy consumption measured in off mode, sleep mode and idle state. Subclauses 4.1 to 4.4 indicate how to
measure the energy consumption in each of those 3 states.
For computers lacking a discrete sleep mode, energy consumption measured in idle state may, under certain
conditions, replace the energy consumption in sleep mode in the applicable formula.
NOTE 1 According to regulation (EU) N° 617/2013, power in idle state (Pidle) may be used in place of sleep mode
(Psleep) for desktop computers and integrated desktop computers that lack a discrete sleep mode, but have idle state
power demand less than or equal to 10 W.
NOTE 2 Examples of theoretical duty cycles applicable to certain categories of computer under Regulation (EU) N°
617/2013 are given in Annex B.
NOTE 3 Applicable limits to the annual total energy consumption may depend on the type of computer as well as the
category of the installed and enabled discrete graphics card(s), if any.
4.6 Internal Power Supply (IPS) efficiency and power factor
The efficiency and the power factor of the internal power supply shall be measured for desktop computers,
integrated desktop computers, thin clients, workstations, small-scale servers and computer servers.
For all types of internal power supplies, the efficiency and the power factor shall be measured at 20 %, 50 %
and 100 % of the rated [nameplate] output power.
For single output internal power supplies, the efficiency shall also be measured at 10 % of the rated
[nameplate] output power.
For single output internal power supplies with a rated output power greater than 500 W, the power factor shall
also be measured at 10 % of the rated [nameplate] output power.
Test setup, test conditions, and measurement instrument specifications shall comply with 6.3.
This test procedure assumes that the internal power supply meets following criteria:
— Detailed input and output ratings are available on the name plate or in manufacturer’s literature,
specifying the maximum loads that can safely be placed on each individual dc output voltage bus and,
where necessary, groupings of those voltage busses.
— The power supply has connectors that allow the d.c. output voltage busses to be connected and
disconnected from the powered product non-destructively.
— The power supply can be easily detached from the housing of the product it powers, without causing
harm to other circuits and components of the product
In the event the above criteria are not met, a test board shall be provided to enable testing.
