1 Scope
This European Technical Report provides guidance on assessing the potential ignition
hazard from the inadvertent extraction of energy from electromagnetic fields, propagated
from communication, radar or other transmitting antennas to plant where a potentially
flammable atmosphere may be present. The frequency range covered by this European Technical Report is
9 kHz to 60 GHz. This European Technical Report does not apply to similar hazards arising from electromagnetic fields generated by other means, such as electric storms,
electricity generating installations or other radiating electrical equipment, nor
does it apply to any hazard arising within telecommunication or other electronic equipment.
NOTE 1 The methods of assessment from 9 GHz to 60 GHz are based on extrapolation of data
for frequencies below 9 GHz.
NOTE 2 The ignition of dust is not covered in this European Technical Report. This European
Technical Report also provides advice on how to mitigate the hazard in cases where the assessment indicates that a hazard may exist. This European Technical Report does not cover the hazards associated with the use of electro-explosive devices (EED) (see CLC/TR 50426), or
the biological hazards of exposure to RF fields.
