Excerpt from Nvlap Seventh Annual Report and Directory of Accredited Laboratories The Commerce Department's National Voluntary Laboratory Accreditation Program (nvlap) is a program to improve the reliability of laboratory measurements through transfer of measurement technology. Critical elements of test methods are identified along with precision and accuracies expected from the methods when measurements are made. Proficiency testing and interlaboratory comparisons contribute to improved test methods and laboratory performance. This seventh annual report provides information on the activities of the National Bureau of Standards (nbs) in carrying out nvlap during calendar year 1983. Voluntary participation by the Nation's laboratories remains stable and several new accreditation programs requested by government agencies and private organizations are in the final stages of development. The accredited laboratories have been found competent to perform the specific tests shown in Part II, the Directory of Accredited Laboratories. They have the skilled people, necessary facilities and equipment, and documentation and quality control procedures to produce quality testing data. We recommend that consideration be given to the use of these laboratories whenever their accredited testing capabilities satisfy testing needs. Nvlap has. Also provided the basis for acceptance by other countries of test data produced by laboratories in the Uni-ted States through development of international guidelines for this purpose. We shall continue to work toward liberalizing the means to satisfying trade requirements whenever possible.
