d)
If the frequency stepping skips over an ISM or amateur band,
as applicable, an additional test frequency shall be used in the
ISM or amateur radio band. This applies to each ISM and amateur
radio band within the specified frequency range.
e)
Testing may be performed at other modulation frequencies
identified by the RISK MANAGEMENT PROCESS.
f)
ME EQUIPMENT and ME SYSTEMS with a d.c. power input
intended for use with a.c.-to-d.c. converters shall be tested
using a converter that meets the specifications of the
MANUFACTURER of the ME EQUIPMENT or ME SYSTEM.
The IMMUNITY TEST LEVELS are applied to the a.c. power input
of the converter.
g)
Applicable only to ME EQUIPMENT and ME SYSTEMS connected
to single-phase a.c. mains.
h)
E.g. 10/12 means 10 periods at 50 Hz or 12 periods at 60 Hz.
i)
ME EQUIPMENT and ME SYSTEMS with RATED input
current greater than 16 A / phase shall be interrupted once
for 250/300 cycles at any angle and at all phases at the same
time (if applicable). ME EQUIPMENT and ME SYSTEMS with
battery backup shall resume line power operation after the
test. For ME EQUIPMENT and ME SYSTEMS with RATED
input current not exceeding 16 A, all phases shall be interrupted
simultaneously.
j)
ME EQUIPMENT and ME SYSTEMS that do not have a surge
protection device in the primary power circuit may be tested
only at ± 2 kV line(s) to earth and ± 1 kV line(s) to line(s).
k)
Not applicable to CLASS II ME EQUIPMENT and ME SYSTEMS.

NOTE If necessary to achieve the IMMUNITY TEST LEVEL, the distance
between the transmitting antenna and the ME EQUIPMENT or ME
SYSTEM may be reduced to 1 m. The 1 m test distance is permitted by
IEC 61000-4-3.

The ISM (industrial, scientific and medical) bands between 0,15 MHz
and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567
MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz. The
amateur radio bands between 0,15 MHz and 80 MHz are 1,8 MHz to 2,0
MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4 MHz, 7 MHz to 7,3 MHz,

MHz and 50,0 MHz to 54,0 MHz.
o)
Applicable to ME EQUIPMENT and ME SYSTEMS with RATED input
current less than or equal to 16 A / phase and ME EQUIPMENT and ME
SYSTEMS with RATED input current greater than 16 A / phase.
p)
Applicable to ME EQUIPMENT and ME SYSTEMS with RATED input
current less than or equal to 16 A / phase.
q)
At some phase angles, applying this test to ME EQUIPMENT with
transformer mains power input might cause an overcurrent protection
device to open. This can occur due to magnetic flux saturation of
the transformer core after the voltage dip. If this occurs, the ME
EQUIPMENT or ME SYSTEM shall provide BASIC SAFETY during and
after the test.
r)
For ME EQUIPMENT and ME SYSTEMS that have multiple voltage
settings or auto ranging voltage capability, the test shall be performed at
the minimum and maximum RATED input voltage. ME EQUIPMENT and
ME SYSTEMS with a RATED input voltage range of less than 25 % of the
highest RATED input voltage shall be tested at one RATED input voltage
within the range. See Table 1 Note c) for examples calculations.

As an alternative to FM modulation, 50 % pulse modulation
at 18 Hz may be used because while it does not represent
actual modulation, it would be worst case.
