3 Definitions
3.13
battery box
Replace the existing definition with the following:
compartment which is separate from the toy or appliance and in which the batteries are
placed
Add the following new definitions after definition 3.23
3.24
clock frequency
the fundamental frequency of any signal used in the device excluding those
which are solely used inside integrated circuits (IC).

– 4 – CISPR 14-1 Amend. 1 © IEC:2008

NOTE High frequencies are often generated inside of integrated circuits (IC) by phase-locked-loop (PLL) circuits

from lower clock oscillator frequencies outside the IC.

3.25
battery-operated appliance
appliance which is operated only from batteries and has no provision for performing its

intended function when connected to the mains, either directly or via a power supply.

NOTE 1 Toys are not considered to be appliances.

NOTE 2 An appliance which has provision for charging but cannot perform its intended function during charging is
considered to be a battery-operated appliance.

3.26
mains-operated appliance
all appliances which are not battery-operated appliances
NOTE Toys are not considered to be appliances.

4 Limits of disturbance
Replace the text immediately preceding subclause 4.1 with the following new text:
Radio disturbance measurements below 148,5 kHz and above 1 000 MHz do not need to be
carried out.
4.1 Continuous disturbance
Replace subclauses 4.1.2 and 4.1.3 by the following:
4.1.2 Frequency range 30 MHz to 1 000 MHz
4.1.2.1 Disturbance power measurement in the frequency range 30 MHz to 300 MHz
The limits of the disturbance power are given in Table 2a. Disturbance power is measured in
accordance with Clause 6, at all terminals.

This subclause describes application of the limits for all appliances (see Figure 10).

Regulating controls which incorporate semiconductor devices, electric fence energizers,
rectifiers, battery chargers and converters, which do not contain any clock frequency higher
than 9 kHz, are not subject to the requirements in the frequency range 30 MHz to 1 000 MHz.

4.1.2.3.2 Mains operated appliances

The equipment under test shall be evaluated for emissions in the 30 MHz to 1 000 MHz range
by testing in accordance with either method a) or b), see also Figure 10.
a) The limits in columns 2 and 3 of Table 2a for the frequency range from 30 MHz to
300 MHz shall be met by all appliances except for electric tools. For electric tools the
