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 ISO 11929-1, advanced applications on the basis of the GUM Supplement 1 in this document, applications to unfolding methods in ISO 11929-3, and guidance to the application in ISO 11929-4. ISO 11929-1 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 ISO 11929-1:2025, Annex A, the special case of repeated counting measurements with random influences is covered, while measurements with linear analogous ratemeters are covered in ISO 11929-1:2025, Annex B. 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 ISO 11929, summarizes shortly the general procedure and then presents a wide range of numerical examples.

This document specifies the identification of radionuclides and the measurement of their activity in soil using in situ gamma spectrometry with portable systems equipped with germanium or scintillation detectors. This document is suitable to rapidly assess the activity of artificial and natural radionuclides deposited on or present in soil layers of large areas of a site under investigation. This document can be used in connection with radionuclide measurements of soil samples in the laboratory (see ISO 18589-3) in the following cases: — routine surveillance of the impact of radioactivity released from nuclear installations or of the evolution of radioactivity in the region; — investigations of accident and incident situations; — planning and surveillance of remedial action; — decommissioning of installations or the clearance of materials. It can also be used for the identification of airborne artificial radionuclides, when assessing the exposure levels inside buildings or during waste disposal operations. Following a nuclear accident, in situ gamma spectrometry is a powerful method for rapid evaluation of the gamma activity deposited onto the soil surface as well as the surficial contamination of flat objects. NOTE The method described in this document is not suitable when the spatial distribution of the radionuclides in the environment is not precisely known (influence quantities, unknown distribution in soil) or in situations with very high photon flux. However, the use of small volume detectors with suitable electronics allows measurements to be performed under high photon flux.

This document gives guidance relating to successful, secure and usable implementation of biometric enrolment processes, while indicating risk factors that organizations which use biometric technologies can address during procurement, design, deployment and operation. Much of this document is generic to many types of applications, e.g. from national scale commercial and government applications, to closed systems for in-house operations, and to consumer applications. However, the intended application and its purpose often have influence on the necessary enrolment data quality and are taken into account when specifying an enrolment system and process. This document specifies the differences in operation relating to specific types of application, e.g. where self-enrolment is more appropriate than attended enrolment. This document focuses on mandatory, attended enrolment at fixed locations. It ultimately consolidates information relating to better practices for the implementation of biometric enrolment capability in various business contexts including considerations of process, function (system), and technology, as well as legal/privacy and policy aspects. This document provides guidance on collection and storage of biometric enrolment data and the impact on dependent processes of verification and identification. This document does not include material specific to forensic and law enforcement applications.

This document specifies a procedure for the evaluation of centreline segregation of continuously cast slabs, including sampling, sample preparation and evaluation method. This document is applicable for low carbon steel slabs for pipe production manufactured by continuous casting. These steels have a typical chemical composition as follows (mass percentages): — C ≤ 0,12 % — Mn ≤ 2,0 % — Si ≤ 0,5 % — Ti + Nb + V ≤ 0,2 % The common dimensions of these slabs are in the following ranges: — Slab width: 800 mm to 2 600 mm — Slab thickness: 150 mm to 450 mm The evaluation methods covered by this document are based on macroscopic etching of slab samples followed by visual inspection by means of human eye or camera systems. The procedures for sampling described in 5.1 to 5.3 of this document are applicable to steels slabs in general (e. g. other steel grades or dimensions). However, the etching procedure (see 5.4) in combination with the evaluation methods described in Clause 6 have been developed especially for the application on pipeline steels as given above. Thus, they are not applicable to other steel grades, product types or dimensions without a prior validation. Any extension or modification beyond the scope of this document necessitates a separate agreement between producer and customer.

This document specifies evaluation methods for determining the content of reactive oxygen species (ROS) used in the FB-facilitated advanced oxidation for pollution abatement in the wastewater treatment process. The probe based kinetic model is applicable to systems that generate ROS in substantial quantities, rather than at physiological concentrations, and is applicable to short-lived ROS. However, it is not applicable to long-lived ROS, such as ozone (O3) and hydrogen peroxide (H2O2). The probe based kinetic model method specifies: — cumulative concentration of different types of ROS during the reaction process; — concentration of different types of ROS at each time point during the reaction process. This method does not define the mechanisms of ROS generation, nor the correlation between bubble size and ROS production.

1.1 General This document specifies methods for determining the sound power level of a noise source from sound pressure levels measured on a surface enveloping the noise source (machinery or equipment) in an environment that approximates to an acoustic free field near one or more reflecting planes. The sound power level produced by the noise source, in frequency bands or with A-weighting applied, is calculated using those measurements. NOTE Differently shaped measurement surfaces can yield differing estimates of the sound power level of a given noise source which are accounted for in the uncertainty associated with this test method. An appropriately drafted noise test code (see ISO 12001) gives detailed information on the selection of the surface. 1.2 Types of noise and noise sources The methods specified in this document are suitable for all types of noise (steady, non-steady, and fluctuating) as defined in ISO 12001, except for short duration, impulsive events. This document is applicable to all types and sizes of noise source (e.g. stationary or slowly moving component or sub-assembly), provided that the conditions for the measurements can be met. NOTE It is possible that the conditions for measurements given in this document are impracticable for very tall or very long sources such as chimneys, ducts, conveyors and multi-source industrial plants. A noise test code for the determination of noise emission of specific sources can provide alternative methods in such cases. 1.3 Test environment The test environments that are applicable for measurements made in accordance with this document can be located indoors or outdoors, with one or more sound-reflecting planes present on or near which the noise source under test is mounted. The ideal environment is a completely open space with no bounding or reflecting surfaces other than the reflecting plane(s), such as that provided by a qualified hemi-anechoic chamber, but procedures are given for applying corrections (within limits that are specified) in the case of environments that are less than ideal. Annex A or ISO 26101-2 specifies methods for determining the adequacy of the test environment and for determination of corrections to be applied to account for the effect of the test environment. 1.4 Measurement uncertainty Information is given on the uncertainty of the sound power levels determined in accordance with this document, for measurements made in limited bands of frequency and with frequency A-weighting applied.
