Referencing NVLAP accreditation
A.1 Conditions for referencing the NVLAP term, logo, and symbol
The term NVLAP and the NVLAP logo are registered marks of the Federal Government, which retains
exclusive rights to control the use thereof. Permission to use the term and symbol (NVLAP logo with
approved caption) is granted to NVLAP-accredited laboratories for the limited purpose of announcing
their accredited status, and for use on reports that describe only testing or calibration within the scope of
accreditation. NVLAP reserves the right to control the quality of the use of the NVLAP term, logo, and
In order to become and remain accredited, laboratories shall comply with the following conditions
pertaining to the use of the term NVLAP, the NVLAP logo, and NVLAP symbol. Failure to comply with
these conditions may result in suspension or revocation of a laboratory’s accreditation.
a) An applicant laboratory that has not yet achieved accreditation may make reference to its applicant
status. If the NVLAP Lab Code is used, it shall be accompanied by a statement accurately
reflecting the laboratory’s status. An applicant laboratory shall not use the NVLAP term, logo or
symbol in a manner that implies accreditation.
b) The laboratory shall have a policy and procedure for controlling the use of the term NVLAP and the
c) The term and/or symbol shall not be used in a manner that brings NVLAP into disrepute or
misrepresents a laboratory’s scope of accreditation or accredited status.
d) When the term NVLAP is used to reference a laboratory’s accredited status, it shall be accompanied
by the NVLAP Lab Code.
e) When the NVLAP symbol is used to reference a laboratory’s accredited status, it shall be
comprised of the NVLAP logo and the NVLAP Lab Code in an approved caption. The caption
shall appear below and in close proximity to the logo. The following captions have been approved
— “For the scope of accreditation under NVLAP Lab Code 000000-0” (Fig. 1);
— “NVLAP Lab Code 000000-0” (Fig. 2).
f) When the NVLAP symbol is used, the form of the NVLAP logo must conform to the following
— The logo shall stand by itself and shall not be combined with any other logo, symbol, or
— The aspect ratio (width to height) shall be 2.25 to 1 (Fig. 3).
The logo and caption shall be of a size that allows the caption to be easily read. The size of the
caption shall not exceed the size of the logo itself.
— The logo shall appear in black, blue, or other color approved by NVLAP, and may be filled or
unfilled. In the case of a filled logo, the same color shall be used for the outline and the fill.
g) The name of at least one Approved Signatory shall appear on a test or calibration report that
displays the NVLAP symbol or references NVLAP accreditation. A computer-generated report
may have the Approved Signatory’s name printed along with the test or calibration results, as long
as there is evidence that there is a system in place to ensure that the report cannot be generated
without the review and consent of the Approved Signatory. There may be legal or contractual
requirements for original signatures to appear on the report.
h) When the term and/or symbol are used on test or calibration reports, such use shall be limited to
reports in which some or all of the data are from tests or calibrations performed by the laboratory
under its scope of accreditation.
A test or calibration report that contains both data covered by the accreditation and data not
covered by the accreditation shall clearly identify the data that are not covered by the accreditation.
The report must prominently display the following statement at the beginning of the report: “This
report contains data that are not covered by the NVLAP accreditation.”
i) When the term and/or symbol are used on test or calibration reports that also include work done by
subcontracted laboratories, such use shall be limited to reports in which some or all of the data are
from tests or calibrations performed by the laboratory under its scope of accreditation.
A test or calibration report that contains both data covered by the accreditation and data provided
by a subcontractor shall clearly identify the data that were provided by the subcontracted
laboratory. The report must prominently display the following statement at the beginning of the
report: “This report contains data that were produced under subcontract by Laboratory X.” If the
subcontracted laboratory is accredited by NVLAP, then its Lab Code should also be stated. If the
subcontracted laboratory is accredited by a body other than NVLAP, then the name of the
accreditation body and the laboratory’s number or other unique identifier should also be stated. If
the subcontracted laboratory is not accredited, then this must be stated.
j) Each test or calibration report bearing the term and/or symbol shall include a statement that the
report must not be used by the client to claim product certification, approval, or endorsement by
NVLAP, NIST, or any agency of the Federal Government.
k) When used in a contract or proposal, the term and/or symbol shall be accompanied by a description
of the laboratory’s scope of accreditation and current accreditation status.
l) Laboratories shall not use the terms certified or registered when referencing their NVLAP
accreditation or conformance to ISO/IEC 17025 requirements. The correct term is accredited.
A.2 Joint ISO-ILAC-IAF Communiqué
On June 18, 2005, a Joint ISO-ILAC-IAF Communiqué on the Management Systems Requirements of
ISO/IEC 17025:2005 was issued. The text of this communiqué reads as follows:
“A laboratory’s fulfillment of the requirements of ISO/IEC 17025:2005 means the laboratory meets both
the technical competence requirements and management system requirements that are necessary for it to
consistently deliver technically valid test results and calibrations. The management system requirements
in ISO/IEC 17025 (Section 4) are written in language relevant to laboratory operations and meet the
principles of ISO 9001:2000 Quality Management Systems—Requirements and are aligned with its
Laboratories may find this language useful when discussing the issue of ISO 9001 certification versus
ISO/IEC 17025 accreditation with its customers. A copy of the Communiqué may be found on the
NVLAP web site.
