ENGINEERING METROLOGY - A MEASURE OF PROGRESS.

In 1952 Mr F. H. Rolt, one of the pioneers of engineering metrology, who had worked at NPL for over 40 years reviewed the progress in this area during the first half of the 20th century. He concluded his lecture by identifying eight topics on which progress could be expected. This paper considers each of these areas and identifies where progress has occurred. The paper concludes with a few new predictions for the next decade or so.
