Excerpt from 1964 Technical Highlights of the National Bureau of Standards: Annual Report, Fiscal Year 1964 The Bureau continued to restrict its calibration work, whenever pos sible, to master standards and high-precision instruments, leaving the cali bration ofio-wer-echelon standards to the standards laboratories of industry and the military services. Requests for calibration of lower-echelon stand ards declined during the year, with an attendant drop in the total volume of calibrations from 75,361items in fiscal 1963 to items in fiscal 1964 (table 1) With this reduction in the calibration load, the Bureau was able to devote a somewhat greater proportion of its resources to the develop. Ment of new and improved standards and measurement methods. Efforts to accelerate calibration procedures through use of automation continued. The calibration times for both gage blocks and surveying tapes were substantially reduced by the use of new equipment and electronic data processing. Improved techniques were also developed for the handling and presentation of data and results in the calibration of proving rings, elastic devices used as standards of force. A digital computer now performs the tasks of accurately fitting the data to an equation, statistically analyzing the fit, and printing out tables of load versus ring deflection.
