Section I:  Prospective TCBs - Application to NIST
 

Once the certification body has obtained ISO/IEC 17065 accreditation from one of the NIST-recognized domestic TCB accreditation bodies (A2LA or ANAB) and is ready to apply for TCB designation, the prospective TCB shall (1) submit Items 1, 2, 3 and 8 directly to NIST via mra [at] nist.gov (mra[at]nist[dot]gov) and (2) request that their accreditation body send Items 5, 6, and 7 and 9 directly to NIST via mra [at] nist.gov (mra[at]nist[dot]gov).

1. TCB information 

a) Name of the Organization (TCB)
b) Address
c) Contact name, title, address (if different from above), email, and phone number
d) Identification number (to be assigned by NIST)
e) FCC Registration Number (FRN #) Prospective TCBs can obtain this FRN from the FCC website

2.  The TCBs ISO/IEC 17065 product certification Scope and Certificate of Accreditation.  These documents must include:

a) Name of accreditation body
b) Date of accreditation
c) Expiration date
d) Accreditation standard (ISO/IEC 17065)
e) Scope of Accreditation covering one or more of the FCC scopes (A1-A4, B1- B4, C*) and each FCC scope title exactly as listed in Table 1 of the TCB Program Roles and Responsibilities Document.  *Note that NIST does not designate TCBs for FCC scope C.

3.  The TCB’s ISO/IEC 17025 Scope and Certificate of Accreditation from its supporting testing laboratory.  These documents must include:

a) Name of lab accreditation body (must be from an FCC-recognized U.S. Test Firm Accreditation Body)
b) Date of accreditation
c) Expiration date
d) Accreditation Standard (ISO/IEC 17025)
e) Scope of laboratory accreditation for TCB scope requirements

Note that the TCB may have more than one supporting test lab.  All supporting test labs for US TCBs must be in the United States and be affiliated/owned by the TCB. 

Additional requirements for the supporting test lab(s) are noted in 4 below.

4. The TCB supporting test lab(s) must be FCC recognized for "core" FCC testing.  

Note that “core” testing, since mid-2024, has been clarified by the FCC to mean that the TCB supporting test lab(s) must be (1) FCC recognized (2) for the appropriate FCC TEST LAB scopes [See Table A1 of the Accredited Test Lab Program Roles and Responsibilities KDB 974614 D01 and the correlation of these FCC TEST LAB scopes to the TCB Scopes in Table 3 of the TCB Program Roles and Responsibilities KDB 641163], with (3) correct frequency coverage, (4) for all products being certified by the TCB. 

Please see the FCC rules reference for the required frequencies here:

§ 2.1057(a) “In all of the measurements set forth in §§ 2.1051 and 2.1053, the spectrum shall be investigated from the lowest radio frequency signal generated in the equipment, without going below 9 kHz, up to at least the frequency shown below:

1. If the equipment operates below 10 GHz: to the tenth harmonic of the highest fundamental frequency or to 40 GHz, whichever is lower.
2. If the equipment operates at or above 10 GHz and below 30 GHz: to the fifth harmonic of the highest fundamental frequency or to 100 GHz, whichever is lower.
3. If the equipment operates at or above 30 GHz: to the fifth harmonic of the highest fundamental frequency or to 200 GHz, whichever is lower.

The FCC has also confirmed, in mid-2024, that the TCB may not certify products for which the affiliated supporting test lab(s) do not have the FCC-recognition for the FCC TEST LAB Scopes to test the products, to the appropriate required frequencies.

Please see the FCC rule part reference specifying the TCB test lab capabilities:

§ 2.962(c)(3), “The TCB shall have the technical expertise and capability to test the equipment it will certify and shall also be accredited in accordance with ISO/IEC 17025 (incorporated by reference, see § 2.910) to demonstrate it is competent to perform such tests.”

The TCB must ensure that the TCB supporting test labs stay up to date with test capabilities and must update the FCC recognition of the supporting test lab(s) as FCC regulations and products change.

NIST will verify that the supporting laboratory is included on the list of FCC-recognized test firms for the appropriate FCC Test Lab Scopes and frequencies to support the TCB scopes – in accordance with the above requirements. See the FCC’s EAS Test Firm Search.

5.  The ISO/IEC 17065 Assessment Report and Deficiency Report issued by the accreditation body.

6.  Corrective action responses for deficiencies that were cited during the ISO/IEC 17065 assessment.

7. FCC TCB Checklist completed by accreditation body assessor.

The accreditor must assess the TCB to all applicable elements of the FCC Checklist. The accreditor shall maintain a copy of all checklists completed during assessments and shall provide a copy of the most recently completed checklist upon request. 

8.  Specify the name(s), title(s), and e-mail addresses of TCB personnel that are qualified to perform the following FCC Key Employee functions:

a) Application Reviewer
b) EMC Reviewer
c) SAR Qualified Reviewer
d) General RF Exposure Reviewer
e) Decision Maker
f) Administrative Contact

9*.  The TCB supporting lab’s final signed FCC Accredited Testing Laboratory Checklist completed by the lab’s accreditation body (and submitted to the FCC during the lab FCC recognition process).  This document must be provided by the accreditation body directly to NIST.  

Please send the above information to NIST electronically via mra [at] nist.gov (mra[at]nist[dot]gov.)
 

Section II:  Active (FCC recognized) U.S. TCBs
 

Renewing FCC TCB Recognition (following Accreditation Renewal) - process as of 9/27/2024 

Each US-located TCB recognized by the FCC must apply for renewal of their recognition prior to the FCC TCB recognition expiration date (which may differ from the accreditation expiration date). 

The application involves submittal of documents by the TCB (see A) and by your Accreditation Body (AB) (see B): 

   A. The TCB shall submit the following to NIST (mra [at] nist.gov (mra[at]nist[dot]gov)) along a request for renewal of the FCC TCB recognition: 

1. Renewed ISO/IEC 17065 Scope and Certificate of Accreditation covering one or more of the FCC scopes (A1-A4, B1- B4, C*) that also includes the full title of each FCC Scope exactly as listed in Table 1 of the TCB Program Roles and Responsibilities Document.  *Note that NIST does not designate TCBs for FCC scope C.
    
2. Current ISO/IEC 17025 Scope and Certificate of Accreditation of the supporting lab(s) that is/are FCC recognized for "core" FCC testing as defined in Section I (4) above.  NIST will verify that the supporting laboratory is included on the list of FCC-recognized test firms for the appropriate test methods to support the TCB scopes. See the FCC’s EAS Test Firm Search. 

   B. Please ask your AB to submit the following to NIST (mra [at] nist.gov (mra[at]nist[dot]gov)):   

3. FCC’s TCB Checklist completed by the AB during the renewal assessment.
