  § 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
   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 fabrication into a device which is subsequently sold (or
   leased) to the user.
