NVLAP Overview:
The National Institute of Standards and Technology (NIST) administers the National Voluntary Laboratory Accreditation Program. NVLAP accredits public and private laboratories based on evaluation of their technical qualifications and competence to carry out specific tests. NVLAP provides an unbiased third party evaluation and recognition of performance, as well as technical resources to improve laboratory performance. This accreditation signifies that a laboratory has demonstrated that it operates in accordance with technical requirements for accreditation, in the areas of quality systems, personnel, accommodations and environmental conditions, test methods and method validation, equipment, measurement traceability, handling of test items, assuring the quality of test results, and reporting results. Accreditation does not imply any guarantee of laboratory performance or test data, it is solely a finding of laboratory competence. Accreditation does not represent an endorsement of any product by NVLAP or any agency of the U.S. government.
