RECOMMENDATIONS FOR SPECIFYING AND TESTING THE SUSCEPTIBILITY OF ACOUSTICAL INSTRUMENTS TO RADIATED RADIOFREQUENCY ELECTROMAGNETIC FIELDS, 25 MHZ TO 1 GHZ
1.1 This Standard provides recommendations for
specifying and testing the susceptibility of acoustical instruments to radiated electromagnetic fields.
The instruments may be powered by batteries or
from a public supply of electric power. Recommendations related to testing an instrument’s susceptibility to electromagnetic radiation are given in annex A. Annex B contains a bibliography of background information.
1.2 The Standard does not contain recommendations
for specifying and testing the susceptibility
of an acoustical instrument to conducted electromagnetic fields. The Standard does not contain recommendations to limit the radio-frequency
electromagnetic fields that may be radiated by an
acoustical instrument. It does not provide recommendations for the influence of radio-frequency
fields on optional external cabling or ancillary devices. The Standard is not applicable to audiometers or hearing aids.
1.3 This Standard provides recommendations for
electric and magnetic field strengths and for radiofrequency and acoustical test signals.
1.4 The Standard covers the range of radio frequencies from 25 MHz to 500 MHz, and an extended
range from 25 MHz to 1 GHz (corresponding
to wavelengths from 12 m to 0.333 m).
1.5 The recommendations of this Standard may
be used to develop radio-frequency electromagnetic
susceptibility requirements for specific
acoustical instruments. For individual instrument
standards, the recommended specifications for
electromagnetic test-signal frequencies, and maximum
field strengths, or any other recommendation
of this Standard, may be modified as appropriate.
