Domestic Recognition of A2LA Programs

Recognition of A2LA programs includes formal written agreements between A2LA and users of accredited services, officially documented endorsements of A2LA programs, and informal acceptance between A2LA and various parties. Below are listed the Federal agencies, State agencies, municipalities and private sector parties with whom A2LA has some type of formal written agreement of recognition or documented endorsement.

Federal Agencies:

  • As of March 25, 2014, the Centers for Medicare and Medicaid Services (CMS) has approved A2LA as an Accreditation Organization for the accreditation of clinical laboratories under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) for all specialty and subspecialty areas under CLIA. CMS grants this "deeming authority" to an Accreditation Organization if its requirements for laboratories accredited under its program are equal to or more stringent than the applicable CLIA program requirements in 42 CFR Part 493. A2LA's program requirements were found to meet or exceed the applicable CLIA requirements and, as a result, A2LA has been granted "deeming authority" by CMS.
  • A2LA has been approved to offer ISO/IEC 17020 assessment and accreditation to Federal Risk and Authorization Management Program (FedRAMP) Third Party Accreditation Organizations (3PAOs) under the FedRAMP Concept of Operations (CONOPS).
  • The Environmental Protection Agency's (EPA) Office of Pollution Prevention and Toxics (OPPT) formally recognizes A2LA as a laboratory accreditation body working in cooperation with the EPA National Lead (Pb) Laboratory Accreditation Program (NLLAP) to accredit lead (Pb) testing laboratories.
  • A2LA is recognized by the United States Environmental Protection Agency (EPA) as an accreditation body for Product Certification Bodies wishing to certify products for the EPA ENERGY STAR Program, as well as being recognized as an accreditation body for testing laboratories wishing to test products for this program.  In January 2011, the EPA implemented a major overhaul to the ENERGY STAR program, and began requiring third-party certification of all products which were to receive the ENERGY STAR mark. Certification Bodies wishing to be recognized by the EPA are required to gain and maintain accreditation to ISO/IEC 17065:2012 from an IAF-MLA signatory accreditation body located in North America. Testing laboratories wishing to be recognized for product testing services must either hold accreditation to ISO/IEC 17025:2005 through a recognized accreditation body, or be part of a recognized certification body’s Witnessed Manufacturer’s Test Lab (WMTL) or Supervised Manufacturer’s Test Lab (SMTL) program.  A2LA is one of a select few accreditation bodies recognized to offer product certification accreditation for the ENERGY STAR program, and is the only American accreditation body which can offer testing (ISO/IEC 17025) and product certification (ISO/IEC 17065) assessments in a ‘one-stop-shop’ setting.
  • The EPA requires all products bearing the WaterSense label to be independently certified by a certification body who has been accredited by one of the approved accreditation bodies, of which A2LA is one. This certification provides consumers with confidence in both the water efficiency and performance of WaterSense labeled products.
  • The U.S Federal Aviation Administration (FAA) recognizes A2LA as an "evaluation authority" as specified in ASTM C1077 "Standard Practice for Laboratories Testing Concrete and Concrete Aggregates for Use in Construction and Criteria for Laboratory Evaluation", Sections. and 11, and as a "national authority" as specified in ASTM D3666, "Standard Specification for Minimum Requirements for Agencies Testing and Inspecting Road and Paving Materials", Section 8.1.5, Note 8.
  • The U.S. Federal Aviation Administration (FAA), in Volume 6, Chapter 9, Section 9 "Inspect a Part 145 Repair Station's Tools and Equipment", requires that all measuring and test equipment be traceable to a standard acceptable to the FAA (such as through an NMI). To meet this requirement, the FAA accepts equipment calibrated by a calibration laboratory that is accredited by an ILAC MRA signatory accreditation body (such as A2LA).
  • The U.S. Federal Communications Commission (FCC) requires that manufacturers and suppliers of personal computers and computer peripherals who intend to use a "Declaration of Conformity" on their products have the products tested by an accredited Electromagnetic Compatibility (EMC) laboratory. A2LA is one of the approved accreditation bodies under this program. Laboratories seeking to be listed with the FCC by virtue of their A2LA Electrical (EMC) accreditation must also meet the technical requirements contained in FCC Part 15 and 47 CFR parts 2 & 15.
  • The U.S. Federal Bureau of Investigation National DNA Index Systems (NDIS) Procedures Board approved the designation of A2LA as an accrediting agency under the United States Federal DNA Identification Act (42 U.S.C. 14132). ( As a designated agency, A2LA, through its Forensic Accreditation Program, is now recognized to accredit laboratories performing DNA anlyses on DNA samples obtained from identified subject(s) for the purposes of entering the resulting DNA profile or DNA record into a DNA database as well as laboratories performing DNA analyses on known or casework reference samples considered evidence by that laboratory. In addition, A2LA is approved to perform biennial audits to the FBI Quality Assurance Standards in accordance with FBI QAS, Section 15.2, which requires that, at least every two years, an external audit be performed.
  • The National Institute of Standards and Technology (NIST) has formally listed A2LA as competent to accredit testing laboratories to meet the technical requirements for acceptance by European Union Member State Governments under the EMC Annex of the U.S. - E.U Mutual Recognition Agreement.  NIST has also listed A2LA as an authorized body under the provisions of Phase I of the Asia Pacific Economic Cooperation (APEC) TEL MRA.
  • The National Institute of Standards and Technology (NIST) has recognized A2LA to accredit testing laboratories under the USGv6 Test Program. This program requires that laboratories performing testing of Internet Protocol version 6 (IPv6) products for use in the United States government be accredited by an ILAC MRA signatory, such as A2LA.
  • The Office of Nuclear Reactor Regulation, in a letter and attached safety evaluation report (SER) issued to the Arizona Public Service Company, approved a requested change to the quality assurance (QA) program of the Palo Verde Nuclear Generating Station Units 1, 2 and 3.  The change provides for acceptance of A2LA accreditation to ISO/IEC 17025 as a means of qualifying calibration laboratories to provide commercial-grade calibration services to the Palo Verde Nuclear Generating Station.  The accreditation process is accepted in lieu of a supplier audit, commercial-grade survey, or in-process surveillance.
  • NIST/NVCASE has listed A2LA for accreditation of product certification bodies that certify products related to telecommunications equipment.

  • The U.S. Consumer Product Safety Commission (CPSC) continues to publish notices in the Federal Register regarding accreditation requirements for third party laboratories that are testing in conformance with the Consumer Product Safety Improvement Act (CPSIA) of 2008. According to these publications and the CPSIA, children's products and their mandatory safety rules (found on the CPSC website) must be tested by a laboratory accredited to ISO/IEC 17025 by an accreditation body (such as A2LA) who is a signatory to the ILAC Mutual Recognition Arrangement (ILAC MRA).
  • The U.S. Navy has placed wording within their NAVAIRINST 2400.20 Instruction to ensure that MIL-STD-461 Electromagnetic Interference (EMI) qualification testing is conducted by public or private laboratories accredited to ISO/IEC 17025.
