Abstract
The Calibration Laboratories Accreditation Program was developed by the National Voluntary Laboratory Accreditation Program (NVLAP) at the National Institute of Standards and Technology (NIST) as a result of interest from private industry and at the request of the National Conference of Standards Laboratories (now the NCSL International). The goal of the program is to provide a means by which calibration laboratories can be assessed for competency. This voluntary program is not designed to serve as a means of imposing specific calibration procedures or minimum uncertainties on applicant laboratories; instead, the program allows for all scientifically valid calibration schemes and requires that laboratories derive and document their measurement uncertainties. To accomplish this goal, NVLAP employs technical experts on a contract basis, to serve as assessors in each of the following eight fields of physical metrology calibration: electromagnetic dc/low frequency, electromagnetic rf/microwave frequency, time and frequency,ionizing radiation, optical radiation, dimensional, mechanical, and thermodynamics.
