§ 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.
