In the regulation titled "Quality Assurance Procedures for Construction" 23 CFR 637 paragraphs 637.209 (a) (2), (3), and (4) require laboratories to be accredited by the AASHTO Accreditation Program or a comparable laboratory accreditation program. On September 22, 2004, the Federal Highway Administration (FHWA) published a Notice in the Federal Register to document the criteria that was going to be used to determine a comparable laboratory accreditation program. Those criteria are now outlined in paragraph 3b of our Non-regulatory Guidance NS 23 CFR, Part 637B.
On May 12, 2011, the Laboratory Accreditation Bureau, L-A-B, was recognized by National Cooperation for Laboratory Accreditation (NACLA) for meeting the technical requirements of the NIST IR 7012 document. The FHWA participated in the evaluation process. The L-A-B meets the requirements for comparable laboratory accreditation bodies listed in the September 22, 2004, Federal Register Notice. As such, the laboratories that are accredited by L-A-B for Construction Materials Testing are considered to meet the quality assurance requirements in 23 CFR 637.209(a) (2), (3), and (4).
