  § 2.948   Measurement facilities.

   (a)  Equipment  authorized  under  the certification or Declaration of
   Conformity  (DoC)  procedure  shall  be tested at a laboratory that is
   accredited in accordance with paragraph (e) of this section.

   (b)  A  laboratory  that makes measurements of equipment subject to an
   equipment  authorization  under the certification, DoC or verification
   procedure  shall  compile  a description of the measurement facilities
   employed.

   (1)  The  description  of the measurement facilities shall contain the
   following information:

   (i) Location of the test site.

   (ii) Physical description of the test site accompanied by photographs that
   clearly show the details of the test site.

   (iii) A drawing showing the dimensions of the site, physical layout of all
   supporting  structures, and all structures within 5 times the distance
   between the measuring antenna and the device being measured.

   (iv) Description of structures used to support the device being measured and
   the test instrumentation.

   (v) List of measuring equipment used.

   (vi) Information concerning the calibration of the measuring equipment,
   i.e., the date the equipment was last calibrated and how often the equipment
   is calibrated.

   (vii) For a measurement facility that will be used for testing radiated
   emissions, a plot of site attenuation data taken pursuant to paragraph (d)
   of this section.

   (2) The description of the measurement facilities shall be provided to a
   laboratory accreditation body upon request.

   (3) The description of the measurement facilities shall be retained by the
   party  responsible  for  verification of equipment and provided to the
   Commission upon request.

   (i) The party responsible for verification of equipment may rely upon the
   description  of  the measurement facilities retained by an independent
   laboratory  that  performed  the  tests.  In this situation, the party
   responsible for verification of the equipment is not required to retain a
   duplicate copy of the description of the measurement facilities.

   (ii) No specific site calibration data is required for equipment that is
   verified for compliance based on measurements performed at the installation
   site of the equipment. The description of the measurement facilities may be
   retained at the site at which the measurements were performed.

   (c) The Commission will maintain a list of accredited laboratories that it
   has recognized. The Commission will make publicly available a list of those
   laboratories that have indicated a willingness to perform testing for the
   general public. Inclusion of a facility on the Commission's list does not
   constitute Commission endorsement of that facility. In order to be included
   on this list, the accrediting organization (or Designating Authority in the
   case of foreign laboratories) must submit the information listed below to
   the Commission's laboratory:

   (1) Laboratory name, location of test site(s), mailing address and contact
   information;

   (2) Name of accrediting organization;

   (3) Scope of laboratory accreditation;

   (4) Date of expiration of accreditation;

   (5) Designation number;

   (6) FCC Registration Number (FRN);

   (7) A statement as to whether or not the laboratory performs testing on a
   contract basis;

   (8) For laboratories outside the United States, the name of the mutual
   recognition agreement or arrangement under which the accreditation of the
   laboratory is recognized;

   (9) Other information as requested by the Commission.

   (d)  When the measurement method used requires the testing of radiated
   emissions on a validated test site, the site attenuation must comply with
   the requirements of Sections 5.4.4 through 5.5 of the following procedure:
   ANSI  C63.4-2014  (incorporated by reference, see § 2.910). Measurement
   facilities used to make radiated emission measurements from 30 MHz to 1 GHz
   shall  comply with the site validation requirements in ANSI C63.4-2014
   (clause 5.4.4) and for radiated emission measurements from 1 GHz to 40 GHz
   shall comply with the site validation requirement of ANSI C63.4-2014 (clause
   5.5.1 a) 1)), such that the site validation criteria called out in CISPR
   16-1-4:2010-04 (incorporated by reference, see § 2.910) is met. Test site
   revalidation shall occur on an interval not to exceed three years.

   (e)  A  laboratory  that has been accredited with a scope covering the
   measurements required for the types of equipment that it will test shall be
   deemed competent to test and submit test data for equipment subject to
   verification,  Declaration  of  Conformity,  and certification. Such a
   laboratory shall be accredited by a Commission recognized accreditation
   organization    based    on   the   International   Organization   for
   Standardization/International Electrotechnical Commission International
   Standard  ISO/IEC  17025, (incorporated by reference, see § 2.910). The
   organization  accrediting  the  laboratory  must  be recognized by the
   Commission's Office of Engineering and Technology, as indicated in § 0.241 of
   this chapter, to perform such accreditation based on International Standard
   ISO/IEC 17011 (incorporated by reference, see § 2.910). The frequency for
   reassessment of the test facility and the information that is required to be
   filed or retained by the testing party shall comply with the requirements
   established by the accrediting organization, but shall occur on an interval
   not to exceed two years.

   (f) The accreditation of a laboratory located outside of the United States,
   or its possessions, will be acceptable only under one of the following
   conditions:

   (1)  If  the  accredited  laboratory  has been designated by a foreign
   Designating Authority and recognized by the Commission under the terms of a
   government-to-government Mutual Recognition Agreement/Arrangement (MRA); or

   (2) If the laboratory is located in a country that does not have an MRA with
   the United States, then it must be accredited by an organization recognized
   by  the  Commission  under  the  provisions  of  § 2.949 for performing
   accreditations in the country where the laboratory is located.
