The American Foundrymen’s Association was the first industrial group to turn over the task of producing samples of standardized iron for its member industries to the NBS in 1905. Before long, the NBS was producing standard samples, now called “Standard Reference Materials (SRMs)” for hundreds of products and materials. The NBS (NIST) today produces more than 1,300 different types of SRMs and sells more than 30,000 units every year.  The NBS built and patented an improved prototype of an Italian-made Radio Direction Finder (RDF) for the U. S. Navy during WWI which was used to pinpoint positions of enemy forces. Thus began the NBS’s association with America’s military forces, and opening new fields of study and endeavors relating to radio electronics.  Since Metrology is the study of measurement, it is expected to enforce, validate and verify predefined standards for traceability, accuracy, reliability, and precision-repeatability. All of these are factors that would affect the validity of measurement. Although these standards vary widely, these are mandated by the government, the agencies, and some treaties. Consequently, these standards are verified and tested against a recognized quality system in calibration laboratories1.

Metrology and the United States Air Force Organizational    structures    were    put    in    place    to    develop    and sustain   precision   measurement   capabilities   ensuring   accurate, reliable,   and   safe   air   and   space   systems   performance   through effective   management   of   the   Air   Force   Metrology   Program   which was   initiated   in   January   of   1952   to   comply   with   AF   Regulation   74- 2,    which    outlined    policies    and    assigned    responsibilities    for managing the Air Force Metrology and Calibration Program. The   Dayton   Air   Force   Depot,   located   at   Gentile   Air   Force   Station in     Dayton,     Ohio,     was     given     the     authority     to     establish     a centralized    calibration    program    whereby    Air    Materiel        Area Depots   were   given   a   set   of   measurement   standards   which   were periodically    calibrated    by    the    Dayton    Air    Force    Depot    using standards traceable to the National Bureau of Standards. On     15     September     1957     base-level     Precision     Measurement Equipment   Laboratories   (PMELs)      were   established   providing   the Air   Force   with   complete   calibration   systems   that   could   handle the   increasingly   stringent   measurement   needs   of   new   missile and aircraft systems.   ( Continued )
