Designs For The Calibration Of Small Groups Of Standards In The Presence Of Drift

Excerpt from Designs for the Calibration of Small Groups of Standards in the Presence of Drift These deviations provide the information needed to obtain a value, 5, which is the experiment's value for the process standard deviation, 0.

This report presents a collection of designs for the intercomparison of sets of weights for use in precision calibration of standards of mass. These include a number of previously unpublished designs which have an additional weight in each set to serve as the check standard for monitoring the performance of the weighing process. Also included are the classical designs of Benoit and Hayford. The complete least squares analysis is presented in integer form (i.e., with a common division) for the most widely used designs; and for the others, the standard deviations are given for various weight combinations when used as an ascending or as a descending series. Designs for sets of nominally equal objects, the 2 2 ... 1 1 ... series, the binary sequences, the 5 2 2 1 1 series, and the 5 3 2 1 1 and some miscellaneous series are given.
