Conducted RF - 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF - 3 V/m
IEC 61000-4-3 80 MHz to 2.5 GHz
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected be absorption and
reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for ratio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicated theoretically with
accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey
should be considered. If the measured field strength in the location in which Dual Pex is used exceeds the applicable RF

<5% UT (>95% dip in UT) for 0.5 cycle
40% UT (60% dip in UT) for 5 cycles
70% UT (30% dip in UT) for 25 cycles
<5% UT (>95% dip in UT) for 5s

3Vw Portable and mobile RF communications equipment should be used no
closer to any part of Dual Pex, including cables, than the recommended
separation distance calculated from the equation applicable to the frequency
of the transmitter.
Recommended separation distance
d=1.2√
d=1.2√
d=2.3√
3.5 V/m
Where P is the maximum output power rating of the transmitter in watts (W)
according to the transmitter manufacturer and d is the recommended separation
distance in meters (m). Field strengths from fixed RF transmitters, as determined
by an electromagnetic site survey, should be less than the compliance level in
each frequency range.**
Interference may occur in the vicinity of equipment marked with the following

Floors should be in wood, concrete or
ceramic tile. If covered by synthetic
material, the relative humidity should
be at least 30 %.
The test is applicable since the EUT
does not have AC/DC power plugs
and signal / interconnecting cable
longer than 3m.
The test is not applicable since the
EUT does not have AC power plug.
The test is not applicable since the
EUT does not have AC power plug.
Power frequency magnetic field
should be at levels characteristic
of a typical location in a typical
commercial or hospital environment.
