1: 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.
*
2: All ME EQUIPMENT and ME SYSTEM cables are attached during the test
.
*
3: Calibration for current injection clamps shall be performed in a 150 Ω system.
*
4: 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.
*
5: Testing may be performed at other modulation frequencies identified by the RISK MANAGEMENT PROCESS.
*
6: 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.
*
7: Applicable only to ME EQUIPMENT and ME SYSTEMS connected to single-phase a.c. mains.
*
8: E.g. 10/12 means 10 periods at 50 Hz or 12 periods at 60 Hz.
*
9: 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.
*
10: 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).
*
11: Not applicable to CLASS II ME EQUIPMENT and ME SYSTEMS.
*
12: Direct coupling shall be used.
*
13: r.m.s., before modulation is applied.
*
14: 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 10,15MHz, 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.
*
6: Before modulation is applied.
*
7: This test level assumes a minimum distance between the ME EQUIPMENT or ME SYSTEM and sources of
power frequency magnetic field of at least 15 cm. if the RISK ANALYSIS shows that the ME EQUIPMENT or
ME SYSTEM will be used closer than 15 cm to sources of power frequency magnetic field, the IMMUNITY
TEST LEVEL shall be adjusted as appropriate for the minimum expected distance.
