3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
The operation mode that under no human operation, relies on sensors, algorithms to
automatically adjust the running gear.
3.5.4 off mode(s)
When the power supply unit of the cleaner is connected to the mains power supply,
there is no standby mode, network mode or active mode, and any mode in which the
state is continuous.
NOTE: An indicator that only informs the user that the cleaner is in the off position is included in
the category of off mode(s). For mode and function guidance, see Annex A of GB/T 35758-2017.
[Source: GB/T 35758-2017, 3.5, modified]
3.5.5 non-network standby mode(s)
Any mode that when the cleaner is connected to the main power supply, there is no
network connectivity function, and one or more of the following user-oriented functions
or protection functions are provided, and it is continuous.
- Other modes (including active mode on or off) can be triggered by triggering
remote switches (including remote control), internal sensors, timers;
- Information or status display including a clock;
- Basing on sensor capabilities.
NOTE: For mode and function guidance, see Annex A of GB/T 35758-2017. A timer is a clock
function (with or without a display) that performs a regularly scheduled task (such as a switch) and
works continuously.
[Source: GB/T 35758-2017, 3.6, modified]
3.5.6 network standby mode(s)
The mode in which the cleaner is connected to mains power and at least one of the
network functions has been activated (such as restarting by network command or
complete network communication), but the main function has not been activated.
NOTE: This mode cannot be used if the network function is not enabled and/or not connected to
the network. Network functions can be triggered by preset command sets or network request
responses. "Network" as used in this document includes communications between two or more
independently powered devices or products. A network does not contain one or more controls for a
single product. A network mode may include one or more standby functions.
[Source: GB/T 35758-2017, 3.7, modified]
3.6 standby power
The corresponding power consumption of the cleaner in off, standby, and network
modes.
NOTE: The unit is watts (W).
3.7 total decay
Under the specified space and conditions, due to the joint action of natural decay and
cleaning operation, the concentration of target pollutants in the air is reduced.
NOTE: Natural decay refers to the reduction of the concentration of target pollutants in the air due
to non-human factors such as settlement, agglomeration, surface deposition, chemical reaction and
air exchange under specified space and conditions.
3.8 clean air delivery rate; CADR
The parameter of the cleaning ability of the cleaner for the target pollutants (particulate
matter and gaseous pollutants) under the specified test conditions. It indicates the rate
at which the cleaner provides clean air.
NOTE: The unit is cubic meter per hour (m3/h).
3.9 cumulate clean mass; CCM
The parameter of the cleaner’s cumulative cleaning capacity against target pollutants
(particulate matter and gaseous pollutants) under specified test conditions. It indicates
the total mass of the target pollutants accumulated for cleaning treatment when the
measured value of the clean air rate of the cleaner decays to 50% of the initial value.
NOTE: The unit is milligram (mg).
3.10 cleaning energy efficiency; η
The amount of clean air produced per unit power consumption by the cleaner in rated
mode.
