This document specifies a method for periodic determination of the axial velocity and volume flow rate of gas within emissions ducts and stacks. It is applicable for use in circular or rectangular ducts with measurement locations meeting the requirements of ISO 15259. Minimum and maximum duct sizes are driven by practical considerations of the measurement devices described within this document. NOTE ISO 15259 is identical to EN 15259[12]. This document requires all flow measurements to have demonstrable metrological traceability to national or international primary standards. This document applies to a range of monitoring objectives with different uncertainty requirements, ranging from very stringent (Emission Trading Schemes and calibration of automated flow measuring systems) to less demanding (support of isokinetic sampling). The level of quality control within this document is determined by the uncertainty requirements of the monitoring objective. Monitoring objectives are grouped based on the required quality control. The document specifies which requirements and performance characteristics apply to specified measurement objectives and application areas. The methods specified in this document can be used as a standard reference method, if the user demonstrates that the performance characteristics of the methods are equal to or better than the performance criteria specified in this document and that the expanded uncertainty of the measurement results obtained by the methods, expressed with a level of confidence of 95 %, is determined and reported. The results for each method defined in this document have different uncertainties within a range of 1 % to 10 % at flow velocities of 20 m/s. Other methods can be used provided that the user can demonstrate equivalence, e.g. based on the principles of EN 14793[11].

Jonizuojančiosios spinduliuotės matavimo būdingųjų verčių ribų (sprendimo ribos, aptikimo ribos ir aprėpties intervalo ribų) nustatymas. Pagrindai ir taikymas. 1 dalis. Paprasti taikymo atvejai (ISO/DIS 11929-1:2025)

The ISO 11929 series specifies a procedure, in the field of ionizing radiation metrology, for the calculation of the "decision threshold", the "detection limit" and the "limits of the coverage interval" for a non-negative ionizing radiation measurand when counting measurements with preselection of time or counts are carried out. The measurand results from a gross count rate and a background count rate as well as from further quantities on the basis of a model of the evaluation. In particular, the measurand can be the net count rate as the difference of the gross count rate and the background count rate, or the net activity of a sample. It can also be influenced by calibration of the measuring system, by sample treatment and by other factors. ISO 11929 has been divided into four parts covering elementary applications in this document, advanced applications on the basis of the ISO/IEC Guide 3-1 in ISO 11929-2, applications to unfolding methods in ISO 11929-3, and guidance to the application in ISO 11929-4. This document covers basic applications of counting measurements frequently used in the field of ionizing radiation metrology. It is restricted to applications for which the uncertainties can be evaluated on the basis of the ISO/IEC Guide 98-3 (JCGM 2008). In Annex A, the special case of repeated counting measurements with random influences is covered, while measurements with linear analogous ratemeters are covered in Annex B. ISO 11929-2 extends the former ISO 11929:2010 to the evaluation of measurement uncertainties according to the ISO/IEC Guide 98-3-1. ISO 11929-2 also presents some explanatory notes regarding general aspects of counting measurements and on Bayesian statistics in measurements. ISO 11929-3 deals with the evaluation of measurements using unfolding methods and counting spectrometric multi-channel measurements if evaluated by unfolding methods, in particular, for alpha- and gamma‑spectrometric measurements. Further, it provides some advice on how to deal with correlations and covariances. ISO 11929-4 gives guidance to the application of the ISO 11929 series, summarizes shortly the general procedure and then presents a wide range of numerical examples. Information on the statistical roots of ISO 11929 and on its current development may be found elsewhere[33][34]. The ISO 11929 series also applies analogously to other measurements of any kind especially if a similar model of the evaluation is involved. Further practical examples can be found, for example, in ISO 18589[1], ISO 9696[2], ISO 9697[3], ISO 9698[4], ISO 10703[5], ISO 7503[6], ISO 28218[7], and ISO 11665[8]. NOTE A code system, named UncertRadio, is available for calculations according to ISO 11929-1 to ISO 11929-3. UncertRadio[31][32] can be downloaded for free from https://www.thuenen.de/de/fi/arbeitsbereiche/meeresumwelt/leitstelle-umweltradioaktivitaet-in-fisch/uncertradio/. The download contains a setup installation file which copies all files and folders into a folder specified by the user. After installation one has to add information to the PATH of Windows as indicated by a pop‑up window during installation. English language can be chosen and extensive "help" information is available.
