Electromagnetic Immunity
The PIEZOART is intended for use in the electromagnetic environment specified below. The customer or the user of
the PIEZOART should assure that is used in such an environment.
Immunity test
IEC 60601
test level
Compliance level Electromagnetic environment – guidance
Conducted RF
IEC 61000-4-6
EN 61000-4-6
3 Vrms
150 kHz to 80 MHz
6 Vrms
In ISM bands from
150 kHz to 80 MHz
Portable and mobile RF communications equipment
should be used no closer to any part of the
PIEZOART
including cables, than the recommended separation
distance calculated from the equation applicable to
the frequency of the transmitter.
Radiated RF
IEC 61000-4-3
EN 61000-4-3
3 V/m
80 MHz to 2.7 GHz
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These specifications may not be applicable in all situations. Electromagnetic propagation is affected by absorption and reflection from structures,
objects and persons.
(a): The electromagnetic field strength of fixed radiofrequency emitters, such as base stations for mobile telephones (cellular / cordless), mobile radio,
AM/FM radio broadcasts and TV broadcasts cannot be determined exactly by theory.
To assess the electromagnetic environment due to fixed radiofrequency emitters, an electromagnetic environment measurement must be made.
If the measured radiofrequency field strength in the immediate environment where the product is used exceeds the compliance level specified above,
the performance of the product must be tested to verify whether it conforms to the specification. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the product.
(b): In the 150 kHz to 80 MHz frequency range, the electromagnetic field strengths must be less than 3V/m.
3 Vrms
150 kHz to 80 MHz
6 Vrms
In ISM bands from
150 kHz to 80 MHz
3 V/m
80 MHz to 2.7 GHz
Recommended separation distance
d = 1.2 √P
d = 1.2 √P 80MHz to 800MHz
d = 2.3 √P 800MHz to 2.7GHz
Where ‘P’ is the maximum output power rating of the transmitter in watt (W)
according to the transmitter manufacturer
‘d’ is the recommended separation distance (m).
The electromagnetic field strength of fixed radiofrequency emitters, which is
determined by an electromagnetic environment measurement (a), must be
less than the compliance level in each frequency range (b).
