§ 18.107 Definitions.
(a) Radio frequency (RF) energy. Electromagnetic energy at any frequency in
the radio spectrum from 9 kHz to 3 THz (3,000 GHz).
(b) Harmful interference. Interference which endangers the functioning of a
radionavigation service or of other safety services or seriously degrades,
obstructs or repeatedly interrupts a radiocommunication service operating in
accordance with this chapter.
(c) Industrial, scientific, and medical (ISM) equipment. Equipment or
appliances designed to generate and use locally RF energy for industrial,
scientific, medical, domestic or similar purposes, excluding applications in
the field of telecommunication. Typical ISM applications are the production
of physical, biological, or chemical effects such as heating, ionization of
gases, mechanical vibrations, hair removal and acceleration of charged
(d) Industrial heating equipment. A category of ISM equipment used for or in
connection with industrial heating operations utilized in a manufacturing or
(e) Medical diathermy equipment. A category of ISM equipment used for
therapeutic purposes, not including surgical diathermy apparatus designed
for intermittent operation with low power.
(f) Ultrasonic equipment. A category of ISM equipment in which the RF energy
is used to excite or drive an electromechanical transducer for the
production of sonic or ultrasonic mechanical energy for industrial,
scientific, medical or other noncommunication purposes.
(g) Consumer ISM equipment. A category of ISM equipment used or intended to
be used by the general public in a residential environment, notwithstanding
use in other areas. Examples are domestic microwave ovens, jewelry cleaners
for home use, ultrasonic humidifiers.
(h) ISM frequency. A frequency assigned by this part for the use of ISM
equipment. A specified tolerance is associated with each ISM frequency. See
(i) Marketing. As used in this part, marketing shall include sale or lease,
offer for sale or lease, advertising for sale or lease, the import or
shipment or other distribution for the purpose of sale or lease or offer for
sale or lease. See subpart I of part 2 of this chapter.
(j) Magnetic resonance equipment. A category of ISM equipment in which RF
energy is used to create images and data representing spatially resolved
density of transient atomic resources within an object.
Note: In the foregoing, sale (or lease) shall mean sale (or lease) to the
user or a vendor who in turn sells (or leases) to the user. Sale shall not
be construed to apply to devices sold to a second party for manufacture or
