Appendix A: Electromagnetic Emissions and Immunity
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 ME EQUIPMENT and ME SYSTEM cables are attached during the test.
c) Calibration for current injection clamps shall be performed in a 150
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.
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 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, 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.
