Applicant laboratories may select the test methods and calibration parameters for inclusion on their scopes of accreditation through the NVLAP Interactive Web System (NIWS) — a secure, self-service web portal. The program-specific NVLAP application forms are no longer maintained and have been removed from NVLAP's website.
Click here to enter the NVLAP Interactive Web System (NIWS).
To browse the list of test methods and calibration parameters that NVLAP currently offers or to search for a particular item, click here to open the Product List Search. This list contains several thousand entries and may be searched by laboratory accreditation program, product designation, or key words.
If you do not see the method or parameter in which you are interested, please contact the NVLAP program manager assigned to that technical area of accreditation. See the Staff Directory for the list of program managers.
