SS-ISO 11095 : 2005

This International Standard: a) outlines the general principles needed to calibrate a measurement system and to maintain that "calibrated" measurement system i a state of statistical control; b) provides a basic method - for estimating a linear calibration funtion under either one of two assumptions relating to the variability of the measurements, - for checking the assumption of linearity of the calibration function and the assumptions on the variability of the measurements, and - for estimating the value of a new unknown quantity by transforming the measured values obtained on that quantity with the calibration function; c) provides a control method for extended use of a calibration function - for detecting when the calibration function needs to be updated, and - for estimating the uncertainty of the measured values after transformation with the calibration function; d) provides two alternatives to the basic method under special conditions; e) illustrates the basic method and the control method with an example.
