Measurement assurance and accreditation

The National Bureau of Standards (NBS) has developed a concept to accredit laboratories which provide electromagnetic power, attenuation, and reflection coefficient calibration services. This program, developed under the general procedures of the National Voluntary Laboratory Accreditation Program (NVLAP) would accredit calibration laboratories for levels of uncertainty equivalent to the uncertainties of measurements made at NBS. Implementation of the program is being delayed pending funding to implement a Measurement Assurance Program (MAP) by NBS. The MAP is a quality assurance program to establish and monitor the uncertainty of measurements being made by participating laboratories on a continuing basis.
