Directory of Professional/Trade Organization Laboratory Accreditation/Designation Programs



C W. Hyer


This directory is a guide to laboratory accreditation and similar types of programs conducted by professional and trade organizations. These programs accredit or designate laboratories or other entities to assist private sector professional societies, trade associations, related certification bodies, their membership, as well as government agencies in carrying out their responsibilities. This accreditation or designation is based on an assessment of the capability of the laboratory to conduct the testing. However, the nature of the assessment varies considerably by organization and program. Entries in this directory are based on information provided by each organization and reflect the orgainzation's view of its activities. Parties interested in laboratory accreditation are referred to NIST SP 808, Directory of Federal Government Laboratory Accreditation/Designation Programs, and NIST SP 815, Directory of State and Local Government Laboratory Accreditation/Designation Programs, which contain information on similar programs conducted at the federal, state, and local government levels. Publication of this directory is part of ongoing NIST efforts to establish and maintain comprehensive information on standards, regulations, laboratory accreditation, certification programs, and related information. This material answers the needs of government, industry and the public for information on private sector laboratory accreditation and related programs.
