Industrial Scientific and Medical (ISM) Equipment [FCC Definition]

What equipment is considered to be Industrial Scientific and Medical (ISM) subject to Part 18?

Industrial, scientific, and Medical (ISM) equipment is defined as 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.1 Typical ISM applications are the production of physical, biological, or chemical effects such as heating ionization of gases, mechanical vibrations, and acceleration of charged particles.

The Commission has historically treated RF devices that transmit a radio signal for purposes such as measuring the level of a fluid in a container or for measuring some quantifiable property of a material as Part 15 devices.2 Due to the modulated transmission of information, the Commission determined that Part 15 intentional transmitters were best treated as low power transmission communication devices as opposed to Part 18 equipment where RF energy is generated for the primary purpose of performing work energy, such as in an industrial heater or microwave oven. [3]

With some other applications, however, the applicability of Part 15 or 18 rules requires a caseby-case analysis. For example, in the case of magnetic resonance imaging systems used to stimulate molecules to produce a detectable RF field to form body images, the Commission determined that the use was so unique that it was appropriate to apply Part 18 rules. 4 Similarly devices that use Nuclear Quadrupole Resonance (NQR) techniques for detecting metal properties, have been authorized under Part 18. In this case, we have focused on the fact that the RF energy is used to excite the molecules to create nuclear resonance of the material to determine its property. For certain wireless charging devices that use load modulation to adjust the instantaneous power levels, it was determined that this function should be appropriately authorized under the Part 18 rules.

More recently, there is the heightened interest with using RF spectrum in the frequency ranges above 95 GHz for devices, including devices designed for terahertz spectroscopy, to analyze material molecular properties and for imaging applications.5 Such applications are also appropriate for a case-by-case analysis. Under this approach, the Office of Engineering and Technology has authorized some equipment operating above 95 GHz designed to detect the presence of powders, solids and liquids inside sealed parcels and envelopes under Part 18 rules. Under the Part 18 rules, such devices have been subject to our Supplier’s Declaration of Compliance (SDoC) procedures.6 Those rules require product to be tested and that compliance information be supplied with the product at the time of marketing.[7] The Commission will continue to review devices using similar techniques or frequency bands on a case-by-case basis to determine if it is appropriate to authorize them under Part 18 rules or some other rules, if applicable.

Ultra-Wide Band FCC Wireless Device Approval

ULTRA-WIDEBAND (UWB) DEVICES FREQUENTLY ASKED QUESTIONS

What guidance is available for the approval of Ultra-Wide Band devices?

Q: What technical characteristics must be measured to demonstrate ultra-wideband (UWB) device compliance to the applicable requirements specified in Part 15 Subpart F?

A: The general technical parameters to be measured and provided in an application for certification are listed in Sections 15.31, 15.33, 15.35(a), 15.35(b), 15.204, 15.207, and 15.521; Sections 15.509 through 15.519 apply for different types of UWB devices. The specific UWB technical characteristics that must be measured include the emission bandwidth, the average and peak power spectral density associated with the fundamental emission, and the average power spectral density associated with unwanted emissions (out-of-band and spurious domain).

 

Q: Are standardized measurement procedures available for performing the requisite compliance measurements?

A: Standardized procedures for measuring the technical parameters necessary to demonstrate compliance to the UWB rule requirements can be found in clause 10.1 of ANSI C63.10-2013.

 

Q: What portion of the emission spectrum from a UWB device is required to be contained within the authorized frequency bands? Is it adequate for just the center frequency to be within the authorized band?

A: For a UWB device emission spectrum, the entire fundamental bandwidth (that portion of the spectrum between the outermost −10 dB points) must be fully contained within the authorized frequency band. Consequently, it is not adequate that just the UWB center frequency be within the authorized
frequency band. For example, the emissions spectrum from a ground penetrating radar (GPR) applying for authorization under Section 15.509 must have its fundamental bandwidth located below 960 MHz.

 

Q: What portion of the emission spectrum from a UWB device is required to be contained within the authorized frequency bands? Is it adequate for just the center frequency to be within the authorized band?

A: For a UWB device emission spectrum, the entire fundamental bandwidth (that portion of the spectrum between the outermost −10 dB points) must be fully contained within the authorized frequency band. Consequently, it is not adequate that just the UWB center frequency be within the authorized
frequency band. For example, the emissions spectrum from a ground penetrating radar (GPR) applying for authorization under Section 15.509 must have its fundamental bandwidth located below 960 MHz.

 

Q: How is the requirement for a UWB device to cease transmission after 10 seconds of inactivity (i.e., Section 15.519(a)(1)) interpreted?

A: An acknowledgement of reception must continue to be received by the UWB device at least once every 10 seconds, or else the device shall cease transmission of any information other than periodic signals for use in the establishment or re-establishment of a communications link with an associated receiver.

 

Q: What types of devices are considered to be “hand held” under Section 15.519?

A: The Commission has authorized a variety of devices under this rule part on a case-by-case basis on the following general principle:

A small size UWB device that is intended to operate outdoors on a frequent basis and is capable
of operating without the need for fixed infrastructure installation (e.g., antennas mounted on poles
or towers). Where it is not practical for the device to actually be held in a person’s hand during
operation, it is sufficient to show that the operator can exercise control over the device, or the
object to which the device is affixed, while the device is operating.

It will still be necessary to evaluate applications for outdoor UWB operations under Section 15.519 on a case-by-case basis to ensure fidelity to the rule intent.

 

Q: What compliance information should be included with an application for certification?

A: In addition to the requirements specified in Sections 2.947, 2.911, 2.1033(b), 15.31, 15.203, and 15.521, the following information is required for the processing of a UWB application for certification:

  • The UWB application category (e.g., imaging device, indoor system, hand held device), and the applicable rule section (among Sections 15.509 through 15.519).
  • The lower and upper −10 dB frequencies (fL and fH, respectively) and the frequency of the maximum observed emission level (fM). Also provide a frequency vs. amplitude plot that graphically depicts these values.
  • The maximum radiated emissions (including narrowband emissions) and the associated frequencies observed in each frequency band identified in the applicable emission limits tables.
  • In the event that no emissions are observed in the aforementioned frequency bands, report the minimum sensitivity (noise floor) of the measurement system in these bands (i.e., show that the measurement system is capable of detecting emissions down to the level indicated by the applicable emissions limit).
  • If applicable, report all digital circuitry emissions exceeding the applicable UWB limits, and provide a complete description of the process used to justify invoking the exception stated in Section 15.521(c).
  • Frequency vs. amplitude plots depicting the measured fundamental emission, the out-of-band emission domain, and the emissions into the GPS frequency bands.
  • Where applicable, indicate the location of required operating labels and/or a manual disable switch.
  • Supporting photographs depicting the measurement system set-up and the device under test.

 

Q: Are there any special considerations for UWB devices applying for modular approval?

A: Modular approval will only be considered for UWB applications under Section 15.519 requirements, regardless of whether the device is intended for indoor or outdoor operation.

 

Q: Are there any other options for certifying UWB devices under FCC rules?

Whenever possible (i.e., if the UWB fundamental emission can be fully contained within the 5925−7250 MHz frequency band), Section 15.250 should be considered as an alternative to either Section 15.517 or Section 15.519.

 

Q: Is there a provision for operating wireless tank level gauges (e.g., level-probing radar) under the UWB rules?

A: Section 15.517(a)(4) authorizes the use of tank level gauges as indoor UWB devices only if they are used within metal or underground storage tanks, and the emissions are directed downward, into
the tank.
