NBS Monograph 163; 78p. February 1979.

Keywords:
Calibration; gage blocks; length; measurement assurance; measurement process control; systematic error; uncertainty.

Abstract:
This monograph is intended for those who need to know on a continuing basis the uncertainty of their gage block calibration procedure. A general discussion of the philosophy of measurement assurance is given first. Then three levels of measurement assurance programs are outlined showing how control over the measurement process can be maintained and how the offset (or systematic error) from the unit of length maintained by the National Bureau of Standards can be made negligible.
