Through the scientific method, repeatability and reproducibility fortify accuracy. Unfortunately, differing operators, equipment, calibration, environment, and time introduce variations and potential inaccuracies in measurements.

An international standard, ISO helps determine the repeatability and reproducibility of a standard measurement method.

Accuracy, Precision, and Trueness ISO uses two terms to describe accuracy: trueness and precision. General considerations are provided in ISO for trueness and precision quantities; therefore, Part One of ISO is intended to be used in conjunction with ISO , as well as any other standard in the series. ISO covers a basic method for estimating the precision of measurement methods. To meet this purpose, the standard details guidance relevant to all personnel concerned with designing, performing or analyzing the results of the tests for estimating precision.

Changes to ISO As the second edition of the international standard, ISO revises the edition and incorporates a corrigendum from It has been changed to: allow the use of alternative scrutiny and outlier detection tests provided that the performance is similar let the user apply modern statistical methods available for calculations of the relevant precision and trueness characteristics feature new guidance on the number of laboratories required for a precision study include new information on the computation of critical values ISO — Accuracy Trueness And Precision Of Measurement Methods And Results — Part 2: Basic Method For The Determination Of Repeatability And Reproducibility Of A Standard Measurement Method is available on the ANSI Webstore.

Other ISO Standards Together, the various ISO standards outline general principles that need to be understood when assessing the accuracy of measurement methods, along with applications and some specific methods.

ISO standards and their stories The Untold History of Algorithm A Bertrand Colson QuoData, Germany I recently faced the problem of trying to understand why different people applying the same algorithm to the same data obtained different results, even though everyone was apparently applying the algorithm correctly. Anyone involved in the evaluation of quantitative proficiency tests has been familiar with it since it was taken over in the ISO in Indeed, it is in the context of PT evaluation that I was confronted with inconsistencies between independent applications of Algorithm A. What I found is that the convergence behavior can be problematic.
