ANNEX IV
MEASUREMENT METHODS AND CALCULATIONS Measurements and calculations shall be made using harmonised standards, the reference numbers of which have been published for this purpose in the Official Journal of the European Union, or other reliable, accurate and reproducible methods, which take into account the generally recognised state of the art.
The following general conditions shall apply when testing networked equipment: (a) To measure the energy consumption in standby mode of networked equipment that has such mode, all network ports of the unit shall be deactivated or disconnected, as applicable.
(b) If the equipment relies on active wired connection to one or more network ports for the intended use, manual deactivation of those network ports is allowed instead of wire disconnection.
(c) The following procedure shall be used for measuring energy consumption in networked standby and for testing the power management function: (1) If the equipment has one type of network port and if two or more ports of that type are available, one of those ports is randomly chosen and that port is connected to the appropriate network complying with the port’s maximum specification.
If the equipment has multiple wireless network ports of the same type, the other wireless ports shall be deactivated if possible.
If the equipment has multiple wired network ports of the same type, the other network ports shall be disconnected.
If only one network port is available, that port is connected to the appropriate network complying with the port’s maximum specification.
The tested unit is switched on.
The device that provides the remotely initiated trigger that will reactivate the tested unit is connected to the appropriate network, switched on, and ready to provide the trigger when required to.
Once the tested unit is switched on and working properly, it is allowed to go into networked standby and the power consumption is measured.
Then the appropriate trigger is given to the unit through the network port and a check is made on whether the equipment is reactivated.
(2) If the equipment has more than one type of network port, for each type of network port the following procedure is repeated.
If two or more network ports of a type are available, one port is chosen randomly for each type of network port and that port is connected to the appropriate network complying with the port’s maximum specification.
If for a certain type of network port only one port is available, that port is connected to the appropriate network complying with the port’s maximum specification.
Wired network ports not used shall be disconnected and wireless ports not used shall be deactivated.
The tested unit is switched on.
The device that provides the remotely initiated trigger that will reactivate the tested unit is connected to the appropriate network, switched on, and ready to provide the trigger when required to.
Once the tested unit is switched on and working properly, it is allowed to go into networked standby and the power consumption is measured.
Then the appropriate trigger is given to the unit through the network port and a check is made on whether the equipment is reactivated.
If one physical network port is shared by two or more types of (logical) network ports, that procedure is repeated for each type of logical network port, with the other logical network ports being logical-disconnected.
(d) For all types of household coffee machines, the measurements shall be performed after completion of the last brewing cycle, or, where applicable, after completion of a descaling process, self-cleaning process or any operation performed by the user, unless an alarm has been triggered requiring user intervention to prevent possible damage or accident.
