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 98-3:2008/Suppl 1:2008. 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/en/institutes/fisheries-ecology/fields-of-activity/marine-environment/coordination-centre-of-radioactivity/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.

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 specifies the general requirements for the measurement and evaluation of human exposure to hand-transmitted shock vibrations. For the purposes of this document, hand-transmitted shock vibration is any impactive or impulsive vibration that the machine or tool produces as a sequence of single events (isolated shock vibrations) linked by periods of no, or lower vibration.
This document specifies parameters for the evaluation of machinery emissions of hand-transmitted shocks in the frequency range covered by ISO 5349-1 (nominally the frequency range covered by the octave bands from 8 Hz to 1 000 Hz).
NOTE            It is recognised that shock vibration often includes substantial high-frequency vibration energy. Therefore, reporting of information on hand-transmitted shock at higher frequencies that those specified in this document can be valuable.

The scope of the present document is to provide the elements needed for elaborating the programme execution logic and drafting the execution plan for the realization of a product.
NOTE 1   In this document, the term “logic” alone is sometimes used for “execution logic”.
NOTE 2   In this document, the term “product” is used to designate the object of the program concerned, and the term “system” is used to designate the product for anything related to system engineering.
NOTE 3   The product is also considered a “system-of-interest” and its enabling systems are also taken into account.
The execution logic and plan enable customers/suppliers to reach an agreement on how their respective processes and activities can be organized.
The aim is to enable each actor in the programme to manage their activities with sufficient visibility of the sequencing of the other stakeholdersʼ activities.
This document belongs to the documents supporting EN 9200 relating to the programme management specification.
The present document describes the principles of programme execution logic and defines the corresponding management requirements. This description is supplemented:
—   on the one hand, in terms of execution logic principles, by:
—   the challenges of a basic logic common to all actors (synchronization);
—   the applicable criteria to set up this basic logic;
—   the translation of this logic into the programme processes;
—   on the other hand, in terms of implementing the execution logic, by:
—   the procedures for practical implementation of the management requirements defined in EN 9200;
—   adaptations of the logic according to the various constraints and specificities of the programme, and justification of these adaptations;
—   the consistency between the basic logic at system level and the logics at subsystem and constituent levels.
The breakdown of clauses as used in this document gives a gradual understanding of the approach to be adopted to construct an execution logic. For instance:
—   Clause 5 presents the end-purpose of a programme execution logic as well as the associated basic concepts and the constituents of this logic;
—   Clause 6 describes and characterizes the process for building the logic;
—   Clause 7 concerns change control to the execution logic;
—   Clause 8 concentrates on the importance of capitalization and lessons learned.
This document applies to aeronautical, space and defence programmes. The principles can be extended to other areas of activity.
It applies to realization of a single product, of several samples or of a series. It applies to any customer/supplier level, while ensuring consistency between successive levels.
The principles described concern all programme actors, from initial expression of need through to closure of the programme.

—   information systems (IS) and the links between them;
—   logistics information systems (LIS);
—   in-service support (ISS) activities;
—   configuration management of ILS objects;
—   life cycle.
The following stakeholders are concerned by ILS:
—   users in the broadest sense: operators, maintenance operators, administrators, dismantlers of the system, trainers;
—   the customer, who:
—   prepares technical and contractual specifications of need with which the system will comply;
—   sets up the funding of the programme;
—   oversees the realization and commissioning of the main system and of the support system;
—   facilitates the feedback.
NOTE 1   At the highest level of the system, the customer can also be referred to as the “project owner”.
NOTE 2   The “main system” can also be referred to as the “system of interest”.
—   the supplier(s) who deliver a system (main and support) to the customer, which meets the performance specifications on time and for the agreed cost, throughout the system life cycle;
NOTE 3   At the highest level of the system, the supplier can also be referred to as the “industrial prime contractor”.
—   the regulatory authorities that supervise and approve the support processes and equipment, as needed.
The principles laid down in this document can be applied, after adaptation, to all the customer/supplier relations resulting from the breakdown of the main contract into sub-contracts.
