20、INTERNATIONALE IS0 11843-1:1997(E/F) Capability of detection - Capacit de dtection - Part 1: Partie 1: Terms and definitions Termes et dfinitions Scope This part of IS0 11843 specifies terms and definitions relating to the detection of a difference between an actual state of a system and its basic s

21、tate. The general concepts laid down in this part of IS0 1 1843, critical value of the response variable, critical value of the net state variable and minimum detectable value of the net state variable (see defi- nitions Nos. 9 to 11 1, apply to various situations such as checking the existence of a

22、 certain substance in a material, the emission of energy from samples or plants, or the geometric change in static systems under distortion. Critical values can be derived from an actual measurement series so as to assess the unknown states of systems included in the series, whereas the minimum dete

23、ctable value of the net state variable as a characteristic of the measurement method serves for the selection of appropriate measurement pro- cesses. In order to characterize a measurement pro- cess, a laboratory or the measurement method, the minimum detectable value can be stated if appropri- ate

24、data are available for each relevant level, .e. a measurement series, a measurement process, a lab- oratory or a measurement method. The minimum detectable values may be different for a measure- ment series, a measurement process, a laboratory or the measurement method. Domaine dapplication La prsen

27、ques sous contraintes. Les valeurs critiques peuvent tre issues dune srie de mesures relles afin destimer les tats inconnus de systmes contenus dans cette srie, tandis que la valeur minimale dtectable de la variable nette dtat en tant que caractristique de la mthode de mesure sert la slection de pro

28、cessus de mesure appro- pris. Pour caractriser un processus de mesure, un laboratoire ou la mthode de mesure, la valeur mini- male dtectable peut tre tablie si des donnes appropries sont disponibles pour chaque niveau concern, cest-dire une srie de mesures, un pro- cessus de mesure, un laboratoire o

29、u une mthode de mesure. Les valeurs minimales dtectables peuvent tre diffrentes pour une srie de mesures, un pro- cessus de mesure, un laboratoire ou la mthode de mesure. 1 STD-ISO Z3893-3-ENGL 1997 II 9853903 0733523 bob IS0 11843-1:1997(E/F) IS0 11843 applies to quantities measured on scales that

30、are fundamentally continuous. It applies to meas- urement processes and types of measurement equipment where the functional relationship between the expected value of the response variable and the value of the state variable is described by a calibration function. If the response variable or the sta

31、te variable is a vectorial quantity, the concepts of IS0 11843 apply separately to the components of the vectors or functions of the components. NOTE - Definitions Nos. 6 and 11 refer to theoretical quantities which in reality remain unknown. Estimates of these theoretical quantities can be determin

32、ed from ex- perimental results. Terms and definitions Without restriction to the general applicability of this part of IS0 11843, it is assumed that the net state variable (see No. 4) is non-negative and that the cali- bration function (see No. 6) is strictly monotonically increasing. See also note

33、1 of definition No. 9. Figure 1 illustrates some of the concepts defined. The form of the distribution of the response variable and the calibration function is only an example and does not imply any restriction to a particular type of distri- bution. The symbols used in this part of IS0 11 843 refer

34、 to figure 1 and are illustrative. They do not form a normative part of this part of IS0 11843. Q IS0 LISO 11843 sapplique aux quantits mesures sur des chelles fondamentalement continues.
