Instructions for Completing a NVLAP Application


General Application Form

A General Application Form must be completed and signed by the Authorized Representative of the applicant laboratory. Before submitting an application for accreditation, the Authorized Representative should review the entire application package and become familiar with NVLAP accreditation requirements.


Program-Specific Application

A Program-Specific Application must be completed for each Field of Accreditation for which an applicant laboratory is requesting accreditation. The Program-Specific Application forms for testing laboratory accreditation programs (LAPs) contain a test method selection list that shows the NVLAP Test Method Code, Test Method Designation, and Title of each test method available for accreditation in a particular field. From this list, applicants select the methods to be considered for accreditation.

In the Calibration Laboratories program, applicants select from a list of calibration laboratory parameters and provide the uncertainty desired for each parameter.


Fee Calculation and Payment

A new applicant laboratory must complete the Fee Payment Instructions and Form and remit a fee with the application. Payment may be made by check, purchase order, wire payment, or credit card (via Pay.gov). An application will not be processed until payment is received.


NIST Handbook 150, NVLAP Procedures and General Requirements

Each applicant should thoroughly review the NVLAP accreditation requirements in NIST Handbook 150 before submitting an application for accreditation. NIST Handbook 150 presents the basic procedures under which NVLAP operates and the general requirements for accreditation of testing and calibration laboratories. Clauses 4 and 5 of the handbook include all managerial and technical requirements of ISO/IEC 17025:2005, General requirements for the competence of testing and calibration laboratories.

Program-Specific Handbooks

NVLAP currently offers 28 program-specific handbooks for the testing and calibration accreditation programs. These handbooks are published as part of the NIST Handbook 150 series and contain the procedures and technical requirements that are specific to a given program. The program-specific handbooks complement and supplement the information contained in NIST Handbook 150. Program-specific handbooks also contain interpretive comments that make the general NVLAP criteria specifically applicable to a program.
