§ 2.948   Description of measurement facilities.

   (a) Each party making measurements of equipment that is subject to an
   equipment authorization under part 15 or part 18 of this chapter,
   regardless of whether the measurements are filed with the Commission or
   kept on file by the party responsible for compliance of equipment
   marketed within the U.S. or its possessions, shall compile a
   description of the measurement facilities employed.

   (1) If the measured equipment is subject to the verification procedure,
   the description of the measurement facilities shall be retained by the
   party responsible for verification of the equipment.

   (i) If the equipment is verified through measurements performed by an
   independent laboratory, it is acceptable for the party responsible for
   verification of the equipment to rely upon the description of the
   measurement facilities retained by or placed on file with the
   Commission by that laboratory. 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) If the equipment is verified based on measurements performed at
   the installation site of the equipment, no specific site calibration
   data is required. It is acceptable to retain the description of the
   measurement facilities at the site at which the measurements were

   (2) If the equipment is to be authorized by the Commission under the
   certification procedure, the description of the measurement facilities
   shall be filed with the Commission's Laboratory in Columbia, Maryland.
   The data describing the measurement facilities need only be filed once
   but must be updated as changes are made to the measurement facilities
   or as otherwise described in this section. At least every three years,
   the organization responsible for filing the data with the Commission
   shall certify that the data on file is current. A laboratory that has
   been accredited in accordance with paragraph (d) of this section is not
   required to file a description of its facilities with the Commission's
   laboratory, provided the accrediting organization (or designating
   authority in the case of foreign laboratories) submits the following
   information to the Commission's laboratory:

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

   (ii) Name of accrediting organization;

   (iii) Date of expiration of accreditation;

   (iv) Designation number;

   (v) FCC Registration Number (FRN);

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

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

   (3) If the equipment is to be authorized under the Declaration of
   Conformity procedure, the laboratory making the measurements must be
   accredited in accordance with paragraph (d) of this section.

   (b) The description shall contain the following information:

   (1) Location of the test site.

   (2) Physical description of the test site accompanied by photographs of
   size A4 (21 cm * 29.7 cm) or 8 *10 inches (20.3 cm * 25.4 cm). Smaller
   photographs may be used if they clearly show the details of the test
   site and are mounted on full size sheets of paper.

   (3) 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.

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

   (5) List of measuring equipment used.

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

   (7) If desired, a statement as to whether the test site is available to
   do measurement services for the public on a fee basis.

   (8) For a measurement facility that will be used for testing radiated
   emissions, a plot of site attenuation data taken pursuant to the
   procedures contained in Sections 5.4.6 through 5.5 of the following
   procedure: American National Standards Institute (ANSI) C63.4-2001,
   entitled "American National Standard for Methods of Measurement of
   Radio-Noise Emissions from Low-Voltage Electrical and Electronic
   Equipment in the Range of 9 kHz to 40 GHz" published by the American
   National Standards Institute on June 22, 2001 as document number
   SH94908. This incorporation by reference was approved by the Director
   of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR
   part 51. Copies of C63.4-2001 may be obtained from: IEEE Customer
   Service, P.O. Box 1331, Piscataway, NJ 08855-1331, or UPS only IEEE
   Customer Service, 445 Hoes Lane, Piscataway, NJ 08854; telephone
   1-800-678-4333 or +1-732-981-0600 (outside the United States and
   Canada). Copies of ANSI C63.4-2001 may be inspected at the following

   (i) Federal Communications Commission, 445 12th Street, SW., Office of
   Engineering and Technology (Room 7-B144), Washington, DC 20554,

   (ii) Federal Communications Commission Laboratory, 7435 Oakland Mills
   Road, Columbia, MD 21046, or

   (iii) at the National Archives and Records Administration (NARA). For
   information on the availability of this material at NARA, call
   202-741-6030, or go to:

   (9) A description of the types of equipment intended to be measured or
   other information regarding the types of measurements that would be
   performed at the test facility.

   (c) The Commission will publish a list of those parties who have filed
   the information required by this section, provided they indicate that
   they wish to perform measurement services for the public on a fee
   basis. However, it should be noted that the Commission does not endorse
   or approve any facility on this list.

   (d) A laboratory that has been accredited with a scope covering the
   required measurements 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 an approved
   accreditation organization based on the International Organization for
   Standardization/International Electrotechnical Commission (ISO/IEC)
   Standard 17025, "General Requirements for the Competence of Calibration
   and Testing Laboratories." The organization accrediting the laboratory
   must be approved by the Commission's Office of Engineering and
   Technology, as indicated in § 0.241 of this chapter, to perform such
   accreditation based on ISO/IEC 58, "Calibration and Testing Laboratory
   Accreditation Systems--General Requirements for Operation and
   Recognition." The frequency for revalidation of the test site 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. However, in all cases, test site revalidation shall occur
   on an interval not to exceed two years.

   (e) 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;

   (2) If the laboratory has been recognized by the Commission as being
   accredited by an organization that has entered into an arrangement
   between accrediting organizations and the arrangement has been
   recognized by the Commission.
