Technical Requirements for Construction Materials Testing
Date Published:April 2003
This document describes accreditation requirements for laboratories operating in the Construction Materials Testing (CMT) field. It was prepared by the Construction Materials Testing Sub-committee of the NACLA (National Association for Laboratory Accreditation Cooperation) Technical Requirements Committee and reflects requirements established by the Federal Highway Administration, Federal Aviation Administration, United States Army Corps of Engineers, and the Bureau of Reclamation to meet their needs for competent construction materials services.
NIST is publishing this document as a public service pursuant to the Institute's responsibilities under the National Technology Transfer and Advancement Act of 1995, which directed NIST to "coordinate Federal, State, and local technical standards activities and conformity assessment activities, with private sector technical standards activities and conformity assessment activities, with the goal of eliminating unnecessary duplication and complexity in the development and promulgation of conformity assessment requirements and measures.''
Internationally accepted criteria for the operation of accreditation bodies and accreditation of laboratories - ISO/IEC Guide 58, Calibration and Testing Laboratory Accreditation Systems - General Requirements for Operation and Recognition and ISO/IEC 17025 General Requirements for the Competence of Testing and Calibration Laboratories - and guidance documents developed by ASTM committees form the basis for this document. The document contains additional requirements to both ISO/IEC Guide 58 and ISO/IEC 17025 specific to the CMT field as stipulated to meet U.S. Federal agency requirements. Technical requirements contained herein are related to the American Association of State Highway Transportation Officials (AASHTO) document R18, "Recommended Practice for Establishing and Implementing a Quality System for Construction Materials Testing Laboratories."
This document is organized such that paragraph numbering is in line with the paragraphs (sections and subsections) of ISO/IEC 17025.
