A laboratory may apply for accreditation in any of the NVLAP Accreditation Programs listed on this page. Accreditation is available to public and private testing and calibration laboratories, including commercial laboratories; manufacturers' in-house laboratories; university laboratories; and federal, state, and local government laboratories. A laboratory located outside the United States may be accredited if it meets the same requirements as domestic laboratories and pays the additional expenses associated with the on-site assessment.
Information required to complete the application process includes general information about the laboratory, contact information, management system documentation, requested scope of accreditation, and payment information. An applicant laboratory must designate an Authorized Representative to commit the laboratory to fulfill the NVLAP Conditions for Accreditation (see NIST Handbook 150, Annex C).
Each applicant should thoroughly review the NVLAP accreditation requirements in NIST Handbook 150, NVLAP Procedures and General Requirements before applying for accreditation. NIST Handbook 150 presents the basic procedures under which NVLAP operates and the general requirements for accreditation of testing and calibration laboratories.
NVLAP also publishes Program-Specific Handbooks containing the procedures and technical requirements that are specific to a particular accreditation program. These handbooks are published as part of the NIST Handbook 150 series and supplement the information contained in NIST Handbook 150.
Additional information about a specific laboratory accreditation program (LAP) may be viewed by clicking on the name of the program in the list at the right.
