PART 18_INDUSTRIAL, SCIENTIFIC, AND MEDICAL EQUIPMENT--Table of Contents

 

                      Subpart A_General Information

 

Sec. 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 Sec. 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.
