Table 7. IEC 60601-1-2 Electromagnetic Immunity
Performance Criteria – Part 2
Guidance and manufacturer's declaration – electromagnetic immunity
The Hub is intended for use in the electromagnetic environment specified below. The customer or the user of the Hub should ensure that it
is used in such an environment.
Immunity Test
Conducted RF IEC
61000-4-6
Radiated RF IEC
61000-4-3
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 by absorption and reflection from
structures, objects and people.
a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur
radio, AM and FM radio broadcast and TV broadcast and TV broadcast cannot be predicted 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 the Hub is used exceeds the applicable RF compliance level above, the Hub should be observed to verify
normal operation. If abnormal operation is observed, additional measures may be necessary, such as reorienting or relocating the Hub.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
IEC 60601 Test Level Compliance Level
3 Vrms 3 V
150 kHz to 80 MHz
3 V/m 3 V/m
80 MHz to 2,5 GHz
Regulatory Information
Electromagnetic Environment – Guidance
Portable and mobile RF communications equipment should
be used no closer to any part of the Hub, including cables,
than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter.
Recommended separation distance
d = 1.2√ P 80 MHz to 800 MHz
d = 2.3√ P 800 MHz to 6.0 GHz
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).
b
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 symbol:
