The purpose is to outline the general principles to be understood when assessing accuracy (trueness and precision) of measurement methods and results, and in applications, and to establish practical estimations of the various measures by experiment. Is concerned exclusively with measurement methods which yield measurements on a continuous scale and give a single value as the test result.

May be applied to a very wide range of materials, including liquids, powders and solid objects, manufactured or naturally occurring, provided that due consideration is given to any heterogeneity of the material.General information.

On the basis of main provisions of ISO standards, reproducibility and repeatability in determination of measured characteristics of. Buy ISO ACCURACY (TRUENESS AND PRECISION) OF MEASUREMENT METHODS AND RESULTS – PART 6: USE IN PRACTICE OF.

Analysis of the results showed that the between- bottle variation was indeed insignificant; the sample was considered to be homogeneous.Subscription pricing is determined by: In this report the following information shall be given: The symbols used in IS0 are given in annex A.Thus results from each laboratory can be considered as replicates under repeatability conditions.

Use in practice of accuracy values.The first condition is actually developed in 4. Learn more about the cookies we use and how to change your settings. Laboratory means and laboratory variances Lab. ISO Accuracy of Measurement Methods and Results PackageAll measurements are to be carried out according to that standard method. The units should be selected on a random basis for distribution. There are three cases, as follows.

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.If the repeatability standard deviation of the standard measurement method has not been previously deter- mined in accordance with IS0s, will be con- sidered to be the best estimate of it. In particular, if outlying values are de- tected, all necessary steps shall be taken to investi- gate the reasons why they have been obtained, including re-appraisal of the suitability of the accepted reference value.Please first log in with a verified email before subscribing to alerts.

The results of this computation are summarized in table B. BS ISO 5725-6:1994When a value for the bias of a measure- ment method is quoted, together with a test result obtained by that method, there 575-6 an implication that the same characteristic is being measured in exactly the same way.Basic methods for the determination of the trueness of a standard sio method – Part 5: It also specifically provides a procedure for obtaining intermediate measures of precision, basic methods for the determination of the trueness of a measurement method, the determination of repeatability and reproducibility of a standard measurement method. Unless otherwise stated, a is assumed to be 0.

The analytical results are listed in tableB. NBN ISO 5725-6It may appear that some laboratories did not use the required equipment or did not work ac- cording to the specified conditions. Here B is the laboratory component of bias, i.Analytical results as percentage Mn Lab. Annex A forms an integral part of this part of IS0 In the former case, the repeatability standard devi- ation, gr, and the reproducibility standard deviation, gR, will be used for the assessment of the trueness of the measurement method.

C Derivation of equations In order for the results of an experiment to be able to detect with a high probability see annex Cl a prede- termined magnitude of bias, the minimum number of laboratories, p, and test results, n, shall satisfy the following equation: IAccuracy trueness and precision of measurement methods 57256 results – Part 1: The variation uso the estimate of the bias of the measurement method is due to the variation in the results of the measurement process and is expressed by its standard deviation computed as in the case of known precision values, or siJzT-yF.
