§ 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 particles.
(d) Industrial heating equipment. A category of ISM equipment used for
or in connection with industrial heating operations utilized in a
manufacturing or production process.
(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 § 18.301.
(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
(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 fabrication into a device which is subsequently sold (or
leased) to the user.
