Immunity to proximity fields form RF wireless communications equipment
The ENCLOSURE PORT of ME EQUIPMENT and ME SYSTEMS shall be tested as specified in Table A using the test
methods specified in IEC 61000-4-3.
The frequencies and services listed in Table A are representative examples that are based on RF communications equipment
in use at the time of publication of this collateral standard. The test specification does not attempt to cover every frequency
and service used in every country. The RISK MANAGEMENT PROCESS should take current communications services into
account. Testing should be performed at the additional frequencies identified that are not represented in Table A.
While communication might not be possible when ME EQUIPMENT that includes radio equipment is tested in its bandwidth,
the ME EQUIPMENT or ME SYSTEM shall still be able to provide its BASIC SAFETY and ESSENTIAL PERFORMANCE.
Guidance And Manufacturer’s Declaration – Electromagnetic Immunity - Input a.c. power
Continued:
a) The test may be performed at any one power input voltage within the ME Equipment or ME SYSTEM RATED voltage
range. If the ME EQUIPMENT or ME SYSTEM is tested at one power input voltage, it is not necessary to re-test at
additional voltages.
b) All the ME EQUIPMENT and ME SYSTEM cables are attached during the test.
c) Calibration for current injection clamps shall be performed in a 150 Ω system.
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 one 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 ± 2kV line(s) to earth and ± 1 kV line(s) to line(s).
k) Not applicable to CLASS II ME EQUIPMENT and ME SYSTEMS.
l) Direct coupling shall be used.
m) r.m.s., before modulation is applied.
n) 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 to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4 MHz, 7
MHz to 7,3 MHz, 10,1 MHz to 10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to 18,17 MHz, 21,0 MHz to 21,4
MHz, 24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 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.
