Determination and use of straight-line calibration functions

DD ISO/TS 28037:2010 Determination and use of straight-line calibration functions

DD ISO/TS 28037 is a Technical Specification concerned with linear, that is, straight-line, calibration functions that describe the relationship between two variables X and Y , namely, functions of the form Y = A + BX.

Although many of the principles apply to more general types of calibration function, the approaches described exploit the simple form of the straight-line calibration function wherever possible.
