IS/ISO 11843 : Part 5 : 2008 : Capability of Detection Part 5 Methodology in the Linear and Non-Linear Calibration Cases

NATIONAL FOREWORD

This Indian Standard (Part 5) which is identical with ISO 11843-5 : 2008 ‘Capability of detection — Part 5: Methodology in the linear and non-linear calibration cases’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Statistical Methods for Quality and Reliability Sectional Committee and approval of the Management and Systems Division Council.

This standard is a part of IS/ISO 11843 which consists of the following parts, under the general title ‘Capability of detection’:

Part 1 Terms and definitions

Part 2 Methodology in the linear calibration case

Part 3 Methodology for determination of the critical value for the response variable when no calibration data are used

Part 4 Methodology for comparing the minimum detectable value within a given value

Part 5 Methodology in the linear and non-linear calibration cases

Both linear and non-linear calibration functions are encountered in practice. This standard treats both cases equally in the context of the capability of detection, by paying attention to the probability distributions of the net state variable (measurand), rather than the calibration functions themselves.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions and terminologies are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
