Guidance and manufacturer's declaration – electromagnetic immunity (continued)
Conducted RF 3Vrms
IEC 61000-4-6 0.15 to 80MHz
6Vrms in ISM bands
Between 0.15 MHz
and 80 MHz
80% AM at 1 kHz
Radiated RF 3V/m
IEC 61000-4-3 80 MHz to 2.7 GHz
80% AM at 1 kHz
Proximity fields from RF wireless communications equipment 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 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 Test Tube Heater is used exceeds the applicable RF compliance level above,
the Test Tube Heater should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the Test Tube
Heater.
b Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3 V/m.
c
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; 7.0 MHz to 7.3 MHz; 10.1 MHz to 10.15 MHz; 14M Hz to 14.2 MHz, 18.07 MHz to
8.17 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.

Portable and mobile RF communications
equipment should be used no closer to
any part of the Test Tube Heater,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommend separation distance
d = 0.6 √P
Recommend separation distance
d = 1.2 √P 80 MHz to 800 MHz
d = 2.3 √P 800 MHz to 2.7 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
metres (m).
