Elastic devices such as load cells and proving rings, when used with comparison measurement techniques, yield uncertainties orders of magnitude smaller than generally accepted.Their use, in direct reading application, is affected by numerous characteristics of materials, as well as the techniques of application and interpretation of data.This paper is intended to present progress made in the evaluation of calibration techniques, to the end that such transducers may be used with a predictable uncertainty in direct reading applications.Attempts are being made to formulate calibration procedures which are consistent with application procedures.The confusion existing in the derivation and application of practical force units is considered sufficient justification for a brief discussion of forces derived from mass standards and gravitational acceleration.(Author).
